+<h2>Tenmon help</h2>
+
+<p>Tenmon is intended primarily for viewing astro photos and images. It supports the following formats:
+<ul>
+    <li>FITS 8, 16, 32 bit integer and 32, 64 bit float</li>
+    <li>XISF 8, 16, 32 bit integer and 32, 64 bit float</li>
+    <li>JPEG, PNG, BMP, GIF, PBM, PGM, PPM and SVG images</li>
+    <li>CR2, CR3, NEF, DNG raw images</li>
+</ul>
+</p>
+
+<h3>Main windows</h3>
+<p>The main window shows the currently loaded image. On the left is the <i>Image info</i> panel which displays details about the loaded image.
+The <i>File system</i> panel shows other images in the same directory as the loaded image. At the top is the main menu and below that is the
+<i>Stretch panel</i> containing various options for auto-stretching linear image data.</p>
+<p>All panels in the interface can be moved around and/or closed. Any closed or non-visible panel can be
+re-opened through the <i>Docks</i> menu at the top.</p>
+<p>At bottom there is status bar that show current lightness or red, green, blue pixel value under mouse cursor then X and Y coordinates and
+if image contain World Coordinate System metadata it show celestial coordinates.</p>
+
+<h3>Opening and saving images</h3>
+<p>To load an image select <i>File->Open</i> and choose the file. After a file is loaded, it becomes visible in the main image panel, and the
+<i>File system</i> panel will show the other images in the same directory.</p>
+<p>The loaded image can be exported to a different format with <i>File->Save as</i>. Any of the formats JPEG, PNG FITS and XISF can be selected.
+In the case of saving JPEG or PNG, the stretch function is applied to the saved image. FITS and XISF are saved/converted without applying the stretch.
+To open an image, you can also drag and drop it to main window.</p>
+
+<h3>View</h3>
+<p>The <i>View</i> menu has options to control the size and scale of displayed images:
+<ul>
+    <li><i>Zoom In</i> and <i>Zoom Out</i> magnify and shrink the image. The mouse wheel can be also used to zoom freely.</li>
+    <li><i>Best fit</i> auto-zooms the image to fit the current size of the window.</li>
+    <li><i>100%</i> will zoom to 1:1 scale.</li>
+    <li><i>Fullscreen</i> enlarges the main window to the whole screen.</li>
+    <li><i>Thumbnails</i> will display small thumbnails for all images in the current directory.</li>
+</ul>
+</p>
+
+<h3>Stretch toolbar</h3>
+<p>This panel changes how images are displayed.
+<br><img src=":/about/stretch-panel.png"></p>
+<p>Starting on the left, there is slider scale with three adjustable points to manually control the stretch.
+<ul>
+    <li>black point - all pixels with lower value (darker) than this setting will be clipped black</li>
+    <li>mid point - defines the value to be stretched to 50% intensity</li>
+    <li>white point - all pixels with higher value (brighter) than this will be clipped white</li>
+</ul>
+Following the slider are 7 buttons for automatic stretching:
+<ul>
+    <li><i>Linked channels</i> toggle stretching each RGB channel individually.</li>
+    <li><i>Auto Stretch</i> automatically apply black and mid points to render the image with optimal brightness.</li>
+    <li><i>Reset</i> reset three values for black, mid and white point to default.</li>
+    <li><i>Invert</i> invert colors to display the image as negative.</li>
+    <li><i>False colors</i> show black and white in false colour palette.</li>
+    <li><i>Debayer CFA</i> Demosaicing black and white image from CFA sensor to color one.</li>
+    <li><i>Apply Auto stretch on load</i> toggle automatically applying Autostretch for each image when loaded.</p>
+</ul>
+
+<h3>Marking images</h3>
+<p>Images can be marked in the <i>Select</i> menu. To show a list of only the marked images, use <i>Select->Show marked</i>.
+This dialog can be useful to clear marks from images. Marked images show a <b>*</b> character in the title bar of the main window.
+Marked images can be copied or moved to a selected directory with <i>File->Copy/Move marked files</i>.
+After copying or moving, the list of marked files is cleared. The list of marked files will be remembered after quitting the program.</p>
+<p>Another way to mark images is in database view where you can select rows and then select mark or unmark action in context menu. Marked
+files will be shown with bold text. Third way to mark files is from thumbnails view where you can press press <i>Shift</i> and click with left
+mouse button and drag across thumbnails to mark them. Holding <i>Ctrl</i> will unmark files.</p>
+
+<h3>File system and tree</h3>
+<p>File system panel contain list of images in current opened directory. You can select file from this list and it will be displayed. It is also possible to
+use arrow keys to go back (left and up) and forth (right and down) between images.</p>
+<p>File tree show file system structure. You can right click to show context menu to perform various actions from <i>File</i> menu. There are also few others
+<ul>
+    <li><i>Set as root directory</i> show only this directory and subdirectories</li>
+    <li><i>Reset root directory</i> show whole file system</li>
+    <li><i>Go up</i> show directory that is one level above current root directory</li>
+</ul>
+</p>
+
+<h3>Database of FITS/XISF files</h3>
+<p>Tenmon can scan a directory of FITS/XISF files and index metadata from FITS headers into it's internal database. This allows searching and sorting images based on that metadata.</p>
+<p>To populate the database, select a directory of FITS/XISF files with <i>File->Index directory</i>.
+After the selected directory is searched, metadata parsed from the images will be stored in the database.
+To refresh the database, run <i>File->Reindex</i>. This will update any changed metadata and remove any record of
+deleted files. To index new files, simply run <i>Index directory</i> again.</p>
+<p>The database is viewed through a panel which is not visible in the default layout.  To add the database panel to the view,
+toggle <i>Docks->FITS/XISF database</i>. Once visible, database panel shows the database as a table with a column for each property.
+Below the table is button to select which columns/properties are displayed.</p>
+
+<p>Also at the bottom of the database panel are three combo boxes and text inputs used for filtering.
+Select the property to filter on with the combo box and in the adjacent text box enter a string to search for in that property.
+These three combo box contain list of all properties that are found during indexing except first five. First one set searching in file name.
+Next two "RA pos" and "DEC pos" allow to filter out indexed images that contain point with entered RA/DEC coordinate. Expected format is three
+number separated by space. In case of "DEC pos" it also accept +- sign. Omitting one or two last number is also valid. Some examples "02 12 32" "-12 43 12" "+45 32" "13".
+So for RA it means hour, minutes and seconds while for DEC it is degrees, minutes and seconds.
+Setting both "RA pos" and "DEC pos" can return images that doesn't contain entered point as it search against minimum and maximum RA/DEC coordinates that images contain.
+"RA range" and "DEC range" filter out images which center coordinate is within entered range.
+Pressing Enter or clicking on <i>Filter</i> button will filter out database record according to search parameter.
+
+<p>Wildcards:
+<ul>
+    <li><b>%</b> (percent) is a wildcard representing zero or more of any characters.</li>
+    <li><b>_</b> (underscore) is a wildcard for exactly one of any character.</i>
+    <li>Without wildcard characters, the exact string must match.</li>
+</ul>
+</p>
+<br><img src=":/about/filter.png"><br>
+This example filters for files where: "Bias" is in the file name, the OBJECT property is "M_42" (where the underscore can be any single character), and the DATE property begins with "2022".
+</p>
+
+
+<h3>Batch processing</h3>
+
+This module allow to write scripts in JavaScript that process image files. Batch Processing window consist from three main parts. On top is list of input files and directories.
+You can add directories or individual files to this list. Directories are scanned recursively to find all files even non image files. This list of files is then passed to script in array named <b>files</b>.
+In script you can then iterate through files like this.
+<pre>for(file of files)
+{
+    if(file.suffix() == "fits")
+    {
+        core.log(file.fileName());
+        file.convert(file.relativeFilePath(), "XISF");
+    }
+}
+</pre>
+<p>Bellow this list is output directory. All relative paths passed as arguments into methods like copy(), move() or convert() will be relative to this output directory. If you pass absolute path to methods then
+this output directory is ignored.</p>
+
+<p>Bellow that is list of scripts. These scripts are located in application data directory. Select script which you want to run by clicking on it. Clicking on <i>Open scripts</i> will open directory with these scripts where you create new and edit them.
+Location of this directory is on Windows: "C:/Users/<USER>/AppData/Roaming/nou/Tenmon"  Linux: "~/.local/share/nou/Tenmon/scripts" MacOS: "~/Library/Application Support/nou/Tenmon/scripts"</p>
+
+<p>Next is Log windows that contain any messages that come from scripts. Mainly calls to <code>core.log()</code> At bottom there buttons that can start or stop execution of selected scripts.</p>
+
+<h4>core</h4>
+There is global object called <b>core</b> that have these methods.
+<ul>
+<li><b>log(message)</b> print message to log window.</li>
+<li><b>mark(file)</b> mark file same way as in GUI. Takes object of type <i>File</i> as argument.</li>
+<li><b>unmark(file)</b>  unmark file same was as in GUI. Takes object of type <i>File</i> as argument.</li>
+<li><b>isMarked(file)</b> check if file was marked.  Takes object of type <i>File</i> as argument.</li>
+<li><b>setMaxThread(maxthread)</b> set maximum number of concurrent thread when doing asynchronous task.</li>
+<li><b>sync()</b> wait until all asynchronous tasks are done.</li>
+<li><b>getString(label = "", text = "")</b> show dialog box to get string value from user. String value passed in first argument is used as description label. Second argument text is default value in text box.
+        Both parameters are optional so calling just <i>getString()</i> is valid. When cancel is pressed it return Undefined.</li>
+<li><b>getInt(label = "", value = 0)</b> show dialog box with input box to retrieve integer value. String value passed in first argument is used as description label.
+        Second parameter is default value in input box. Both parameters are optional. When cancel is pressed it return Undefined.</li>
+<li><b>getFloat(label = "", value = 0, decimals = 3)</b> show dialog box with input box to retrieve decimal value. String value passed in first argument is used as description label.
+        Second parameter is default value in input box. All three parameters are optional. When cancel is pressed it return Undefined.</li>
+<li><b>getItem(items)</b> show selection dialog which allow to select one item from array of items. It return selected item as string. When cancel is pressed it return Undefined.</li>
+</ul>
+
+<h4>File</h4>
+In <b>files</b> array there are instances of type <b>File</b> objects that have these methods.
+<ul>
+<li><b>fileName()</b> returns the name of the file, excluding the path.</li>
+<li><b>absoluteFilePath()</b> returns an absolute path including the file name.</li>
+<li><b>absolutePath()</b> returns an absolute path without the file name</li>
+<li><b>relativeFilePath()</b> return relative path including file name relative to directory that was in list of directories to be scanned. For example you add C:/images as input directory. In this directory there
+        is file <i>C:/images/lights/red/M42_001.fits</i> then this method will return <i>lights/red/M42_001.fits</i></li>
+<li><b>relativePath()</b> return same path as previous method just without file name. <i>lights/red</i></li>
+<li><b>baseName()</b> return file name up to the first dot. For example for <i>some.file.name.fits</i> it will return <i>some</i></li>
+<li><b>completeBaseName()</b> return file name up to the last dot. For example for <i>some.file.name.fits</i> it will return <i>some.file.name</i></li>
+<li><b>suffix()</b> return string after last dot in file name. For example <i>fits</i></li>
+<li><b>size()</b> return size of file in bytes.</li>
+<li><b>fitsKeywords()</b> return array of strings with every keyword that is in header. <i>SIMPLE,BITPIX,NAXIS,NAXIS1,NAXIS2,EXTEND,COMMENT</i></li>
+<li><b>fitsValue(key)</b> return value for keyword. In case that there is multiple occurrences it return last one.</li>
+<li><b>fitsValues(key)</b> return array of values for keyword.</li>
+<li><b>fitsRecords()</b> return array of objects with properties <b>key, value</b> and <b>comment</b> </li>
+<li><b>modifyFITSRecords(FITSRecordModify)</b> modify FITS header by adding, removing or updating FITS record. Return true on success. Refer to <i>FITSRecordModify</i></li>
+<li><b>isMarked()</b> return true if file is marked.</li>
+<li><b>copy(newpath)</b> copy file to new location. It return instance of new <i>File<i> object that represent this copied file. This path can be relative or absolute. In case that <i>newpath</i> parameter is relative
+        path then it "Output directory" from GUI windows is used as base directory. Parameter <i>newpath</i> can absolute path. File is then copied to this path. In case that copy fail it return null.</li>
+<li><b>move(newpath)</b> move file to new location. It return false if move failed. This can happend if destination is not writable but also if destination file already exist. This functions does not overwrite existing file.
+        This path can be relative or absolute. In case that <i>newpath</i> parameter is relative path then it "Output directory" from GUI windows is used as base directory. Parameter <i>newpath</i> can be absolute path.
+        File is then moved to this path.</li>
+<li><b>convert(outpath, format, params)</b> convert image file from any format that program is able to open into FITS, XISF, JPEG, PNG, BMP.
+        Parameters are: <i>outputpath</i> path where converted image will be saved. It automatically replace suffix according to format. <i>format</i> one of "FITS" "XISF", "JPG", "PNG" or "BMP". <i>params</i> object with attributes "compressionType" and "compressionLevel".
+        Valid values for compressionType are be "gzip" or "rice" when converting to FITS. When converting to XISF compressionType can be "zlib", "lz4", "lz4hc", "zstd", "zlib+sh", "lz4+sh", "lz4hc+sh", "zstd+sh".
+        It is recommended to use "+sh" variants of compression.
+        XISF format also accept "compressionLevel" in range 0-100 where zero is fastest compression and 100 slowest. If you omit this attribute or set it to -1 then default compression level will be used.
+        It return new instance of <i>File</i> that point to converted file.
+<pre>file.convert("converted_file.xisf", "xisf", {"compressionType": "zstd+sh", "compressionLevel": 70});
+file.convert("converted_file.fits", "fits", {"compressionType": "rice"});
+file.convert("converted_file.jpg", "png");</pre>
+</li>
+<li><b>convertAsync(outpath, format, params)</b> same as previous method but it does conversion in separated thread asynchronously and in parallel. Before calling any method on object returned by this method you must call
+        <code>core.sync();</code> to ensure that conversion is done and destination file exists.
+        <pre>let compression = {"compressionType": "zstd+sh"};
+let convertedFiles = [];
+for(file in files)

+</ul>
+
+<h4>FITSRecordModify</h4>
+This class is used to define modify operation FITS header in FITS and XISF files. It can remove update and add records. Order of operation is also remove then update and last add.
+The keyword names may be up to 8 characters long and can only contain uppercase letters, the digits 0-9, the hyphen, and the underscore character.
+<pre>let modify = new FITSRecordModify();
+modify.updateKeyword("OBJECT", "M42");
+modify.updateKeyword("MYTILE", "PART1", "adding custom keyword so WBPP can group it");
+modify.removeKeyword("OBJECT");
+// doesn't matter that it is specified as last. This will first remove
+// existing OBJECT record and then add again OBJECT=M42
+for(file in files)
+{
+    file.modifyFITSRecords(modify);
+}</pre>
+
+<ul>
+<li><b>new FITSRecordModify()</b> create new instance of object.</li>
+<li><b>removeKeyword(key);</b> specify removing of record with <i>key</i> as keyword.</li>
+<li><b>updateKeyword(key, value, comment = "")</b> specify updating existing keyword with value and comment. Comment is optional parameter. If record with keyword doesn't exist then it will add new one.
+        Unless you want to have multiple records with same keyword (for example HISTORY) always use this method and not addKeyword.</li>
+<li><b>addKeyword(key, value, comment = "")</b> specify adding new keyword</li>

+<h2>Aide de Tenmon</h2>
+
+<p>Tenmon est destiné principalement à la visualisation de photos et d'images astronomique. Il prend en charge les formats suivants :
+<ul>
+    <li>FITS 8, 16 bit entier et 32 bit point flottant</li>
+    <li>XISF 8, 16 bit entier et 32 bit point flottant</li>
+    <li>images JPEG, PNG, BMP, GIF, PBM, PGM, PPM et SVG</li>
+    <li>images RAW CR2, CR3, NEF, DNG</li>
+</ul>
+</p>
+
+<h3>Fenêtre principale</h3>
+<p>La fenêtre principale affiche l'image actuellement chargée. Sur la gauche se trouve le panneau <i>Informations de l'image</i> qui affiche des détails sur l'image chargée. 
+Le panneau <i>Système de fichier</i> affiche d'autres images dans le même répertoire que l'image chargée. 
+En haut se trouve le menu principal et en dessous se trouve le panneau <i>Réglage de la luminosité</i> contenant diverses options pour l'étirement automatique des images linéaires.</p>
+<p>Tous les panneaux de l'interface peuvent être déplacés et/ou fermés. Tout panneau fermé ou non visible peut être rouvert via le menu  <i>Fenêtres encrables</i> en haut.</p>
+<p>En bas, il y a une barre d'état qui affiche l'intensité ou la valeur du pixel rouge, vert, bleu sous le curseur de la souris, puis les coordonnées X et Y et, 
+si l'image contient des métadonnées du World Coordinate System, elle affiche les coordonnées célestes.</p>
+
+<h3>Ouvrir et enregistrer des images</h3>
+<p>Pour charger une image, sélectionnez <i>Fichier->Ouvrir</i> et choisissez le fichier. Une fois qu'un fichier est chargé, 
+il devient visible dans le panneau d'image et le panneau du <i>système de fichiers</i> affiche les autres images dans le même répertoire.</p>
+<p>L'image chargée peut être exportée dans un format différent avec <i>Fichier->Enregistrer sous</i>. Tous les formats JPEG, PNG FITS et XISF 
+peuvent être sélectionnés. Dans le cas d'un enregistrement JPEG ou PNG, la fonction d'étirement de la luminosité est appliquée à l'image enregistrée. 
+FITS et XISF sont enregistrés/convertis sans appliquer l'étirement. 
+Pour ouvrir une image, vous pouvez également la faire glisser et la déposer dans la fenêtre principale.</p>
+
+<h3>Voir</h3>
+<p>Le menu <i>Voir</i> propose des options pour contrôler la taille et l'échelle des images affichées :
+<ul>
+     <li><i>Zoom avant</i> et <i>Zoom arrière</i> agrandissent et rétrécissent l'image. La molette de la souris peut également être utilisée pour zoomer librement.</li>
+     <li><i>Meilleur ajustement</i>, zoom automatiquement l'image pour l'adapter à la taille actuelle de la fenêtre.</li>
+     <li><i>100 %</i>, zoom à l'échelle 1:1.</li>
+     <li><i>Plein écran</i> agrandit la fenêtre principale sur tout l'écran.</li>
+     <li><i>Vignettes</i>, affiche de petites vignettes pour toutes les images du répertoire actuel.</li>
+</ul>     
+<p>
+
+<h3>Barre d'outils du réglage de la luminosité</h3>
+<p>Ces outils modifient la luminosité des images affichées.
+<br><img src=":/about/stretch-panel.png"></p>
+<p>À partir de la gauche, il y a une échelle de luminosité avec trois points réglables pour contrôler manuellement l'étirement.
+<ul>
+    <li>point noir - tous les pixels avec une valeur inférieure (plus sombre) que ce paramètre seront écrêtés en noir</li>
+    <li>point médian - définit la valeur à étirer à 50 % d'intensité</li>
+    <li>point blanc - tous les pixels avec une valeur supérieure (plus lumineuse) que celle-ci seront écrêtés en blanc</li>
+</ul>
+Après le curseur se trouvent 5 boutons pour la luminosité automatique :
+<ul>
+    <li><i>Luminosité automatique</i>, applique automatiquement les points noirs et moyens pour rendre l'image avec une luminosité optimale.</li>
+    <li><i>Réinitialiser</i>, réinitialise les trois valeurs pour le point noir, moyen et blanc par défaut.</li>
+    <li><i>Inverser</i>, inverse les couleurs pour afficher l'image en négatif.</li>
+    <li><i>Super pixel CFA </i>, moyenne 2x2 pixels en un (adapté aux images d'une caméra couleur).</li>
+    <li><i>Appliquer la luminosité automatique au chargement</i>, applique la luminosité automatique pour chaque image lors du chargement.</p>
+</ul>
+
+<h3>Marquer les images</h3>
+<p>Les images peuvent être marquées dans le menu <i>Sélectionner</i>. Pour afficher une liste des seules images marquées, utilisez <i>Sélectionner->Afficher marqué</i>. Cette boîte de dialogue peut être utile pour effacer les marques des images. Les images marquées affichent un caractère <b>*</b> dans la barre de titre de la fenêtre principale. Les images marquées peuvent être copiées ou déplacées vers un répertoire sélectionné avec <i>Fichier->Copier/Déplacer les fichiers marqués</i>. Après la copie ou le déplacement, la liste des fichiers marqués est effacée. La liste des fichiers marqués sera mémorisée après avoir quitté le programme.</p>
+<p>Une autre façon de marquer des images est dans la vue de la base de données où vous pouvez sélectionner des lignes, puis sélectionner l'action marquer ou décocher dans le menu contextuel. Les fichiers marqués seront affichés en texte gras. La troisième façon de marquer les fichiers est de voir les vignettes où vous pouvez appuyer sur <i>Maj</i> et cliquer avec le bouton gauche de la souris et faire glisser sur les vignettes pour les marquer. Maintenir <i>Ctrl</i> décochera les fichiers.</p>
+
+<h3>Système de fichier et arborescence</h3>
+<p>Le panneau du système de fichiers contient la liste des images du répertoire ouvert. Vous pouvez sélectionner un fichier dans cette liste et il sera affiché. Il est également possible 
+d'utiliser les touches fléchées pour revenir en arrière (gauche et haut) et avancer (droite et bas) entre les images.</p>
+<p>L'arborescence des fichiers montre la structure du système de fichiers. Vous pouvez cliquer avec le bouton droit de la souris pour afficher un menu contextuel permettant d'effectuer diverses actions du menu <i>Fichier</i>. Il y a aussi les actions suivantes
+<ul>
+    <li><i>Définir comme répertoire racine</i> afficher uniquement ce répertoire et ses sous-répertoires</li>
+    <li><i>Réinitialiser la racine</i> afficher tout le système de fichiers</li>
+    <li><i>Monter</i> afficher le répertoire qui est un niveau au-dessus du répertoire racine actuel</li>
+</ul>
+</p>
+
+<h3>Base de donnée de fichiers FITS/XISF</h3>
+<p>Tenmon peut analyser un répertoire de fichiers FITS/XISF et indexer les métadonnées des en-têtes FITS dans sa base de données interne. Cela permet de rechercher et de trier des images en fonction de ces métadonnées.</p>
+<p>Pour remplir la base de données, sélectionnez un répertoire de fichiers FITS/XISF avec <i>Fichier->Indexer le répertoire</i>. Une fois le répertoire parcouru, les métadonnées analysées à partir des images seront stockées dans la base de données. Pour actualiser la base de données, exécutez <i>Fichier-> Ré-indexer les fichiers</i>. Cela mettra à jour toutes les métadonnées modifiées et supprimera tout enregistrement de fichiers supprimés. Pour indexer de nouveaux fichiers, exécutez simplement à nouveau <i>Fichier->Indexer le répertoire</i>.</p>
+<p>La base de données est visualisée via un panneau qui n'est pas visible dans la mise en page par défaut. Pour ajouter le panneau de base de données à la vue, basculez <i>Fenêtres encrables->Base de données FITS/XISF</i>. Une fois visible, le panneau de la base de données affiche la base de données sous forme de tableau avec une colonne pour chaque propriété. Sous le tableau se trouve un bouton pour sélectionner les colonnes/propriétés à afficher.</p>
+
+<p>Au bas du panneau de la base de données se trouvent également trois boîtes de liste déroulante et des entrées de texte utilisées pour le filtrage. Sélectionnez la propriété à filtrer dans une liste déroulante et dans la zone de texte adjacente, entrez un texte à rechercher pour cette propriété.
+Ces trois boîtes contiennent la liste de toutes les propriétés qui sont trouvées pendant l'indexation, sauf les trois premières. La première définit la recherche dans le nom du fichier.
+Les deux suivantes "RA pos" et "DEC pos" permettent de filtrer les images indexées qui contiennent un point avec les coordonnées RA/DEC entrée. Le format attendu est trois nombres séparés par un espace. 
+Dans le cas de "DEC pos", il accepte également le signe +-. L'omission d'un ou deux derniers chiffres est également valable. Quelques exemples "02 12 32" "-12 43 12" "+45 32" "13".
+Le fait de définir à la fois "RA pos" et "DEC pos" peut renvoyer des images qui ne contiennent pas le point saisi, car la recherche est faite sur les coordonnées RA/DEC minimum et maximum que les images contiennent.
+"RA range" et "DEC range" filtrent les images dont les coordonnées centrale se trouvent dans la plage saisie.
+En appuyant sur la touche Enter ou en cliquant sur le bouton <i>Filtre</i>, les enregistrements de la base de données seront filtrés en fonction des paramètres de recherche.
+
+<p>Caractères génériques :
+<ul>
+     <li><b>%</b> (pourcentage) est un caractère générique représentant zéro ou plusieurs caractères.</li>
+     <li><b>_</b> (trait de soulignement) est un caractère générique pour exactement un caractère quelconque.</li>
+     <li>En l'absence de caractères génériques, le texte exacte doit correspondre.</li>
+</ul>
+</p>
+<br><img src=":/about/filter.png"><br>
+Cet exemple filtre les fichiers où : "Bias" figure dans le nom de fichier, la propriété OBJECT est "M_42" (où le trait de soulignement peut être n'importe quel caractère) et la propriété DATE commence par "2022".
+</p>
+
+<h3>Traitement par lot</h3>
+
+Ce module permet d'écrire des scripts en JavaScript qui traitent des fichiers images. La fenêtre de traitement par lots se compose de trois parties principales. En haut se trouve la liste des fichiers et répertoires d'entrée.
+Vous pouvez ajouter des répertoires ou des fichiers individuels à cette liste. Les répertoires sont analysés de manière récursive pour trouver tous les fichiers, même les fichiers non image. Cette liste de fichiers est ensuite transmise au script dans un tableau nommé  <b>files</b>.
+Dans le script, vous pouvez ensuite parcourir les fichiers comme ici.
+<pre>for(file of files)
+{
+    if(file.suffix() == "fits")
+    {
+        core.log(file.fileName());
+        file.convert(file.relativeFilePath(), "XISF");
+    }
+}
+</pre>
+
+<h4>core</h4>
+Il existe un objet global appelé <b>core</b> qui possède ces méthodes.
+<ul>
+<li><b>log(message)</b> afficher le message dans la fenêtre du journal.</li>
+<li><b>mark(file)</b> marquer le fichier de la même manière que dans l'interface graphique. Prend un objet de type <i>File</i> comme argument.</li>
+<li><b>unmark(file)</b>  décoche le fichier de la même manière que dans l'interface graphique. Prend un objet de type <i>File</i> comme argument.</li>
+<li><b>isMarked(file)</b> vérifie si le fichier a été marqué. Prend un objet de type <i>File</i> comme argument.</li>
+<li><b>setMaxThread(maxthread)</b> définir le nombre maximal de threads simultanés lors de l'exécution d'une tâche asynchrone.</li>
+<li><b>sync()</b> attendre que toutes les tâches asynchrones soient terminées.</li>
+<li><b>getString(label = "", text = "")</b> affiche la boîte de dialogue pour obtenir un text de l'utilisateur. La valeur text passée dans le premier argument est utilisée comme label de description. Le texte du deuxième argument est la valeur par défaut dans la zone de texte.
+        Les deux paramètres sont facultatifs, donc l'appel à <i>getString()</i> est valide. Lorsque vous appuyez sur Annuler, il renvoie Undefined</li>
+<li><b>getInt(label = "", value = 0)</b> affiche une boîte de dialogue avec une zone de saisie pour récupérer une valeur entière. Le texte passé dans le premier argument est utilisé comme label de description.
+Le deuxième paramètre est la valeur par défaut dans la zone de saisie. Les deux paramètres sont facultatifs. Lorsque vous appuyez sur Annuler, il renvoie Undefined.</li>
+<li><b>getFloat(label = "", value = 0, decimals = 3)</b> affiche une boîte de dialogue avec une zone de saisie pour récupérer une valeur décimale. Le texte passé dans le premier argument est utilisé comme label de description.
+Le deuxième paramètre est la valeur par défaut dans la zone de saisie. Les trois paramètres sont facultatifs. Lorsque vous appuyez sur Annuler, il renvoie Undefined.</li>
+<li><b>getItem(items)</b> affiche une boîte de dialogue de sélection qui permet de sélectionner un élément dans un tableau d'éléments. Lorsque vous appuyez sur Annuler, il renvoie Undefined.</li>
+</ul>
+
+<h4>File</h4>
+Dans le tableau <b>files</b>, il y a des instances d'objets de type <b>File</b> qui ont ces méthodes.
+<ul>
+<li><b>fileName()</b> renvoie le nom du fichier, à l'exclusion du chemin.</li>
+<li><b>absoluteFilePath()</b> renvoie un chemin absolu incluant le nom du fichier.</li>
+<li><b>absolutePath()</b> renvoie un chemin absolu sans le nom du fichier</li>
+<li><b>relativeFilePath()</b> renvoie le chemin relatif incluant le nom du fichier par rapport au répertoire qui était dans la liste des répertoires à analyser. Par exemple, vous ajoutez C:/images comme répertoire d'entrée. Dans ce répertoire, il y a
+le fichier <i>C:/images/lights/red/M42_001.fits</i>, alors cette méthode renverra <i>lights/red/M42_001.fits</i></li>
+<li><b>relativePath()</b> renvoie le même chemin que la méthode précédente, mais sans le nom de fichier. <i>lights/red</i></li>
+<li><b>baseName()</b> renvoie le nom du fichier jusqu'au premier point. Par exemple, pour <i>some.file.name.fits</i>, il renverra <i>some</i></li>
+<li><b>completeBaseName()</b> renvoie le nom du fichier jusqu'au dernier point. Par exemple, pour <i>some.file.name.fits</i>, il renverra <i>some.file.name</i></li>
+<li><b>suffix()</b> renvoie la chaîne après le dernier point du nom de fichier. Par exemple <i>fits</i></li>
+<li><b>size()</b> renvoie la taille du fichier en octets.</li>
+<li><b>fitsKeywords()</b> renvoie un tableau de chaînes avec chaque mot-clé présent dans l'en-tête. <i>SIMPLE,BITPIX,NAXIS,NAXIS1,NAXIS2,EXTEND,COMMENT</i></li>
+<li><b>fitsValue(key)</b> renvoie la valeur pour le mot-clé. En cas d'occurrences multiples, la dernière est renvoyée.</li>
+<li><b>fitsValues(key)</b> renvoie un tableau de valeurs pour le mot clé.</li>
+<li><b>fitsRecords()</b> renvoie un tableau d'objets avec des propriétés <b>key, value</b> et <b>comment</b> </li>
+<li><b>modifyFITSRecords(FITSRecordModify)</b> modifier l'en-tête FITS en ajoutant, supprimant ou mettant à jour l'enregistrement FITS. Renvoie true en cas de succès. Reportez-vous à <i>FITSRecordModify</i></li>
+<li><b>isMarked()</b> renvoie true si le fichier est marqué.</li>
+<li><b>copy(newpath)</b> Copie le fichier vers un nouvel emplacement. Il renvoie une instance du nouvel objet <i>File<i> qui représente ce fichier copié. Ce chemin peut être relatif ou absolu. Dans le cas où le paramètre <i>newpath</i> est un chemin relatif, le "Répertoire de sortie" des fenêtres de l'interface graphique est utilisé comme répertoire de base. Le paramètre <i>newpath</i> peut être un chemin absolu. Le fichier est ensuite copié vers ce chemin. En cas d'échec de la copie, il renvoie null.</li>
+<li><b>move(newpath)</b> déplacer le fichier vers un nouvel emplacement. Il renvoie false si le déplacement a échoué. Cela peut se produire si la destination n'est pas accessible en écriture mais aussi si le fichier de destination existe déjà. Cette fonction n'écrase pas le fichier existant.
+Ce chemin peut être relatif ou absolu. Dans le cas où le paramètre <i>newpath</i> est un chemin relatif, le "répertoire de sortie" des fenêtres de l'interface graphique est utilisé comme répertoire de base. Le paramètre <i>newpath</i> peut être un chemin absolu.
+Le fichier est ensuite déplacé vers ce chemin.</li>
+<li><b>convert(outpath, format, params)</b> Convertir un fichier image à partir de n'importe quel format que le programme peut ouvrir en FITS, XISF, JPEG, PNG, BMP.
+Les paramètres sont : <i>outputpath</i> chemin où l'image convertie sera enregistrée. Il remplace automatiquement le suffixe en fonction du format. <i>format</i> l'un des éléments suivants : "FITS", "XISF", "JPG", "PNG" ou "BMP". <i>params</i> objet avec les attributs "compressionType" et "compressionLevel".
+Les valeurs valides pour compressionType sont "gzip" ou "rice" lors de la conversion en FITS. Lors de la conversion en XISF, compressionType peut être "zlib", "lz4", "lz4hc", "zstd", "zlib+sh", "lz4+sh", "lz4hc+sh", "zstd+sh".
+Il est recommandé d'utiliser les variantes de compression "+sh".
+Le format XISF accepte également les "compressionLevel" dans la plage 0-100, où zéro est la compression la plus rapide et 100 la plus lente. Si vous omettez cet attribut ou le définissez sur -1, le niveau de compression par défaut sera utilisé.
+Il renvoie une nouvelle instance de <i>File</i> qui pointe vers le fichier converti.
+<pre>file.convert("converted_file.xisf", "xisf", {"compressionType": "zstd+sh", "compressionLevel": 70});
+file.convert("converted_file.fits", "fits", {"compressionType": "rice"});
+file.convert("converted_file.jpg", "png");</pre>
+</li>
+<li><b>convertAsync(outpath, format, params)</b> même méthode que la précédente, mais effectue la conversion dans un thread séparé de manière asynchrone et en parallèle. Avant d'appeler une méthode sur un objet renvoyé par cette méthode, vous devez appeler
+        <code>core.sync();</code> pour s'assurer que la conversion est effectuée et que le fichier de destination existe.
+        <pre>let compression = {"compressionType": "zstd+sh"};
+let convertedFiles = [];
+for(file of files)
+{
+    if(file.suffix() == "fits")
+        convertedFiles.push(file.convertAsync("xisf/" + file.fileName(), "XISF", compression));
+}
+core.sync(); // ensure that files exist
+for(file of convertedFiles)// now we can iterate over the files
+{
+    core.log(file.fileName() + " " + file.size()); // let print compressed file sizes
+}</pre></li>
+<li><b>stats()</b> calculer les statistiques d'images de base et les renvoyer sous forme d'objet avec des attributs "mean", "stddev", "median", "min", "max" et "mad".
+<pre>let s = file.stats();
+core.log("Median value is " + s.median);</pre></li>
+</ul>
+
+<h4>FITSRecordModify</h4>
+Cette classe est utilisée pour définir l'en-tête FITS des opérations de modification dans les fichiers FITS et XISF. Elle peut supprimer, mettre à jour et ajouter des enregistrements. L'ordre des opérations est également le suivant : suppression, puis mise à jour et enfin ajout.
+Les noms des mots-clés peuvent comporter jusqu'à 8 caractères et ne peuvent contenir que des lettres majuscules, les chiffres de 0 à 9, le trait d'union et le caractère de soulignement.
+<pre>let modify = new FITSRecordModify();
+modify.updateKeyword("OBJECT", "M42");
+modify.updateKeyword("MYTILE", "PART1", "adding custom keyword so WBPP can group it");
+modify.removeKeyword("OBJECT");
+// Peu importe qu'il soit spécifié comme dernier. Cela supprimera d'abord
+// l'enregistrement OBJECT existant, puis ajoutera à nouveau OBJECT=M42
+for(file in files)
+{
+    file.modifyFITSRecords(modify);
+}</pre>
+
+<ul>
+<li><b>new FITSRecordModify()</b> créer une nouvelle instance de l'objet.</li>
+<li><b>removeKeyword(key);</b> spécifier la suppression de l'enregistrement avec <i>key</i> comme mot-clé.</li>
+<li><b>updateKeyword(key, value, comment = "")</b> spécifiez la mise à jour du mot-clé existant avec la valeur et le commentaire. Le commentaire est un paramètre facultatif. Si l'enregistrement avec le mot-clé n'existe pas, il en ajoutera un nouveau.
+À moins que vous ne souhaitiez avoir plusieurs enregistrements avec le même mot-clé (par exemple HISTORY), utilisez toujours cette méthode et non addKeyword.</li>
+<li><b>addKeyword(key, value, comment = "")</b> spécifier l'ajout d'un nouveau mot-clé</li>
+</ul>

+<h2>Tenmon pomocník</h2>
+
+<p>Tenmon slúži primárne na zobrazenie astronomických fotiek a obrázkov. Dokáže otvoriť nasledovné formáty:
+<ul>
+    <li>FITS 8, 16, 32 bitové celočíselné 32 a 64 bitové s plávajúcou čiarkou</li>
+    <li>XISF 8, 16, 32 bitové celočíselné 32 a 64 bitové s plávajúcou čiarkou</li>
+    <li>JPEG, PNG, BMP, GIF, PBM, PGM, PPM a SVG obrázky</li>
+    <li>CR2, CR3, NEF, DNG raw obrázky</li>
+</ul>
+</p>
+
+<h3>Hlavné okno</h3>
+<p>V hlavnom okne sa zobrazujú načítané obrázky. Naľavo sú potom <i>Informácie o obrázku</i> kde sa zobrazujú podrobné
+informácie o aktuálnom obrázku a <i>Zoznam súborov</i> kde sú všetky obrázky z adresára kde je aktuálne zobrazený obrázok.
+Hore je hlavné menu a pod ním je <i>Panel úrovní</i>. Všetky panely sa dajú zavrieť a presúvať. Zatvorený panel sa dá znova
+zobraziť v menu <i>Dokovacie panely</i>.
+</p>
+
+<h3>Otváranie a ukladanie obrázkov</h3>
+<p>Otvoriť obrázok je možné v menu <i>Súbor->Otvoriť</i>. Po vybraní súboru ktorý sa má otvoriť je
+tento zobrazený v hlavnom okne. Taktiež sú v panely <i>Súborový systém</i> zobrazené ďalšie obrázky v
+adresári kde sa nachádza zobrazený obrázok.</p>
+<p>Aktuálne zobrazený obrázok je možné uložiť v inom formáte cez voľbu <i>Súbor->Ulož ako</i>. Dá sa vybrať
+formát JPEG, PNG, FITS a XISF. V prípade JPEG alebo PNG sa aplikuje funkcia na úpravu úrovní. Pri FITS a XISF
+sa dáta skonvertujú bez zmeny úrovní.</p>
+
+<h3>Zobrazenie</h3>
+<p>Menu <i>Zobrazenie</i> ovplyvňuje veľkosť a škálu zobrazovaných obrázkov.
+<i>Priblížiť/Oddialiť</i> zväčší a zmenší obrázok. Na toto tiež slúži aj kolečko myši. <i>Najlepšia veľkosť</i> zobrazí
+obrázok tak aby bol zobrazený na celú plochu. <i>100%</i> zobrazí obrázok v pomere 1:1. <i>Celá obrazovka</i> zobrazí
+hlavné okno na celú obrazovku. <i>Náhľady</i> zobrazí malé náhľady pre všetky obrázky z aktuálneho adresára.
+</p>
+
+<h3>Panel úrovní</h3>
+<p>
+Tento panel umožňuje upraviť spôsob ako sa zobrazujú obrazové dáta. Ako prvá je na tomto panely posuvná škála
+na ktorej sa dajú nastaviť tri body.
+<br><br><img src=":/about/stretch-panel.png">
+<ul>
+    <li>čierny bod - všetky pixeli s hodnotou menšou ako nastavená budú zobrazené ako čierne</li>
+    <li>stredný bod - pixeli s touto hodnotou budú zobrazené ako 50% šedá</li>
+    <li>biely bod - pixeli nad touto hodnotou budú zobrazené ako biele</li>
+</ul>
+Prvé tlačidlo prepína prepojenie nastavenia čierneho, stretdného a bieleho bodu. Po prepnutí sa dá každý farebný kanál nastaviť
+samostatne.
+Nasleduje tlačidlo ktoré nastaví hodnoty čierneho a stredného bodu tak aby bol obrázok zobrazený optimálnym jasom.
+Druhé tlačidlo resetuje hodnoty pre čierny, stredný a biely bod na východzie hodnoty. Invertovanie farieb zobrazí obrázok ako negatív.
+Falošné farby zobraí čiernobiele obrázky vo farebnej škále.
+Prevoď CFA na farbu prevedie demozaikovanie čiernobieleho obrázku na farebný.
+Posledné tlačidlo zapína a vypína nastavovanie optimálnych hodnôt úrovní pre každý obrázok zvlášť.</p>
+
+<h3>Označovanie obrázkov</h3>
+<p>Obrázky je možné si označiť cez menu <i>Výber</i>. Zoznam takto označených obrázkov sa dá zobraziť cez
+<i>Výber->Ukázať označené</i>. V tomto dialógu sa dá tiež tento zoznam upraviť. Okrem toho sa pri označených
+obrázkoch zobrazuje znak * v záhlaví hlavného okna. Takto označené obrázky je potom možné skopírovať alebo
+presunúť do vybraného adresára pomocou <i>Súbor->Skopírovať/Presunúť označené súbory</i>. Po skopírovaní alebo
+presunutú sa zoznam označených obrázkov vymaže. Program si tento zoznam pamätá aj po svojom ukončení.</p>
+<p>Ďalší spôsob ako označiť obrázky je cez databázu FITS/XISF kde je možné vybrať jednotlivé riadky. Potom stačí
+vybrať označit alebo odznačiť v kontextovom menu. Označené súbory budú zobrazené tučným textom. Tretí spôsob na označenie
+obrázkov je možné cez náhľady. Držaním <i>Shift</i> a následne kliknutím ľavým tlačítkom myši sa daný obrázok označí.

+
+<h3>Databáza FITS/XISF súborov</h3>
+<p>Program vie prehľadať adresár a indexovať meta údaje z FIST a XISF obrázkov do internej databázy v ktorej sa dá
+následne vyhľadávať. Najprv je treba indexovať adresár s FIST/XISF obrázkami <i>Súbor->Indexovať adresár</i>.
+Vybraný adresár je prehľadaný a meta údaje z FIST a XISF obrázkov sú uložené do databázy. Na kontrolu a obnovu datábazy
+je možné spustiť re-indexáciu <i>Súbor->Reindex</i>. Toto obnoví zmenené údaje a odstráni záznamy o už neexistujúcich súboroch.
+Pre indexovanie nových súborov je treba znova pustiť indexáciu.</p>
+<p>Pre zobrazenie databázy je treba zobraziť jej panel cez <i>Dokovacie panely->Databáza FITS/XISF súborov</i>. Databáza je zobrazená vo forme tabuľky
+kde sú jednotlivé stĺpcoch zobrazené vybrané vlastnosti. V spodnej časti panelu je tlačidlo ktoré zobrazí dialóg na výber zobrazovaných
+sĺpcov. Nasledujú tri výberové a textové polia. Tieto slúžia na vyhľadávanie v databáze. Výberové pole určuje stĺpec v ktorom sa
+má vyhľadávať a do textového poľa sa zadáva hodnota na vyhľadanie.
+
+<p>Zastupné znaky:
+<ul>
+    <li><b>%</b> (percent) je zastupný znak reprezentujúci žiadný alebo hocikoľko znakov.</li>
+    <li><b>_</b> (underscore) je zastupný znak nahrádzajúci presne jeden znak.</i>
+    <li>Bez zástupných znako sa hľadá presná zhoda.</li>
+</ul>
+</p>
+
+<br><img src=":/about/filter.png"><br>
+V nasledovnom príklade sa vyhľadajú súbory ktoré majú v mene súboru "Bias", OBJECT je M_42 a DATE začína reťazcom 2022. Znak % sa berie ako
+zástupný znak za hocijaký reťazec znakov aj žiadny. Znak _ je tiež zástupný znak zastupujúci práve jeden znak.
+Bez použitia zástupných znakov sa vyhľadá iba presný výskyt.</p>
+
+<h3>Hromadné spracovanie</h3>
+
+Tento modul umožnuje písanie skriptov v JavaScripte ktoré spracujú súbory obrázkov. Okno Hromadného spracovanie pozostáva z troch častí. Navrchu je zoznam vstupných súborov a adresárov.
+Do zoznamu môžete pridať adresáre alebo jednotlivé súbory. Adresáre sú rekurzívne prehľadané na všetky súbory. Zoznam súborov je potom predaný do skriptu ako pole nazvané <b>files</b>.
+V skripte potom cez toto pole iteruje nasledovne.
+<pre>for(file in files)
+{
+    if(file.suffix() == "fits")
+    {
+        core.log(file.fileName());
+        file.convert(file.relativeFilePath(), "XISF");
+    }
+}
+</pre>
+
+<h4>core</h4>
+V skripte je dostupný globálny objekt nazvaný <b>core</b> ktorý má nasledovné metódy.
+<ul>
+<li><b>log(message)</b> vypíše message do okna záznamu.</li>
+<li><b>mark(file)</b> označí súbor rovnako ako cez GUI. Parameter je objekt typu <i>File</i>.</li>
+<li><b>unmark(file)</b>  odznačí súbor rovnako ako cez GUI. Parameter je objekt typu <i>File</i>.</li>
+<li><b>isMarked(file)</b> overenie či je súbor označený.  Parameter je objekt typu <i>File</i>.</li>
+<li><b>setMaxThread(maxthread)</b> nastavý maximálny počet paralelných vlákien pri vykonávaní asynchrónnych úloh.</li>
+<li><b>sync()</b> počká kým sa dokončia všetky asynchrónne úlohy.</li>
+<li><b>getString(label = "", text = "")</b> ukáže dialóg pre získanie textovej hodnoty od používateľa. Prvý parameter je textový popis. Druhý parameter je východzia hodnota. Obydva parametre sú voliteľné takže aj volanie <i>getString()</i> je valdiné.
+        Metoda vracia textový retazec alebo Undefined ak bolo stlačené tlačidlo zrušiť.</li>
+<li><b>getInt(label = "", value = 0)</b> ukáže diálog pre získanie celočíselnej hodnoty. Prvý parameter je textový popis. Druhý parameter je východzia hodnota. Obydva parametre sú voliteľné. Vracia zadané číslo alebo ak je stlačené tlačidlo zrušiť vráti Undefined.</li>
+<li><b>getFloat(label = "", value = 0, decimals = 3)</b> ukáže diálog pre získanie reálneho čísla. Prvý parameter je textový popis. Druhý parameter je východzia hodnota. Tretí parameter je počet desatinných miest.
+        Obydva parametre sú voliteľné. Vracia zadané číslo alebo ak je stlačené tlačidlo zrušiť vráti Undefined.</li>
+<li><b>getItem(items)</b> ukáže dialog pre výber jednej hodnoty z poľa hodnôt. Vracia vybranú hodnotu ako String alebo ak je stlačené tlačidlo zrušiť vráti Undefined.</li>
+</ul>
+
+<h4>File</h4>
+V poli <b>files</b> sú inštancie objektu typu <b>File</b> ktorý ma nasledovné metódy.
+<ul>
+<li><b>fileName()</b> returns the name of the file, excluding the path.</li>
+<li><b>absoluteFilePath()</b> returns an absolute path including the file name.</li>
+<li><b>absolutePath()</b> returns an absolute path without the file name</li>
+<li><b>relativeFilePath()</b> return relative path including file name relative to directory that was in list of directories to be scanned. For example you add C:/images as input directory. In this directory there
+        is file <i>C:/images/lights/red/M42_001.fits</i> then this method will return <i>lights/red/M42_001.fits</i></li>
+<li><b>relativePath()</b> return same path as previous method just without file name. <i>lights/red</i></li>
+<li><b>baseName()</b> return file name up to the first dot. For example for <i>some.file.name.fits</i> it will return <i>some</i></li>
+<li><b>completeBaseName()</b> return file name up to the last dot. For example for <i>some.file.name.fits</i> it will return <i>some.file.name</i></li>
+<li><b>suffix()</b> return string after last dot in file name. For example <i>fits</i></li>
+<li><b>size()</b> return size of file in bytes.</li>
+<li><b>fitsKeywords()</b> return array of strings with every keyword that is in header. <i>SIMPLE,BITPIX,NAXIS,NAXIS1,NAXIS2,EXTEND,COMMENT</i></li>

+<li><b>modifyFITSRecords(FITSRecordModify)</b> modify FITS header by adding, removing or updating FITS record. Return true on success. Refer to <i>FITSRecordModify</i></li>
+<li><b>isMarked()</b> return true if file is marked.</li>
+<li><b>copy(newpath)</b> copy file to new location. It return instance of new <i>File<i> object that represent this copied file. This path can be relative or absolute. In case that <i>newpath</i> parameter is relative
+        path then it "Output directory" from GUI windows is used as base directory. Parameter <i>newpath</i> can absolute path. File is then copied to this path. In case that copy fail it return null.</li>
+<li><b>move(newpath)</b> move file to new location. It return false if move failed. This can happend if destination is not writable but also if destination file already exist. This functions does not overwrite existing file.
+        This path can be relative or absolute. In case that <i>newpath</i> parameter is relative path then it "Output directory" from GUI windows is used as base directory. Parameter <i>newpath</i> can be absolute path.
+        File is then moved to this path.</li>
+<li><b>convert(outpath, format, params)</b> convert image file from any format that program is able to open into FITS, XISF, JPEG, PNG, BMP.
+        Parameters are: <i>outputpath</i> path where converted image will be saved. It automatically replace suffix according to format. <i>format</i> one of "FITS" "XISF", "JPG", "PNG" or "BMP". <i>params</i> object with attributes "compressionType" and "compressionLevel".
+        Valid values for compressionType are be "gzip" or "rice" when converting to FITS. When converting to XISF compressionType can be "zlib", "lz4", "lz4hc", "zstd", "zlib+sh", "lz4+sh", "lz4hc+sh", "zstd+sh".
+        It is recommended to use "+sh" variants of compression.
+        XISF format also accept "compressionLevel" in range 0-100 where zero is fastest compression and 100 slowest. If you omit this attribute or set it to -1 then default compression level will be used.
+        It return new instance of <i>File</i> that point to converted file.
+<pre>file.convert("converted_file.xisf", "xisf", {"compressionType": "zstd+sh", "compressionLevel": 70});
+file.convert("converted_file.fits", "fits", {"compressionType": "rice"});
+file.convert("converted_file.jpg", "png");</pre>
+</li>
+<li><b>convertAsync(outpath, format, params)</b> same as previous method but it does conversion in separated thread asynchronously and in parallel. Before calling any method on object returned by this method you must call
+        <code>core.sync();</code> to ensure that conversion is done and destination file exists.
+        <pre>let compression = {"compressionType": "zstd+sh"};
+let convertedFiles = [];
+for(file of files)
+{
+    if(file.suffix() == "fits")
+        convertedFiles.push(file.convertAsync("xisf/" + file.fileName(), "XISF", compression));
+}
+core.sync(); // ensure that files exist
+for(file of convertedFiles)// now we can iterate over the files
+{
+    core.log(file.fileName() + " " + file.size()); // let print compressed file sizes
+}</pre></li>
+<li><b>stats()</b> calculate basic images statistics and return them as object with attributes "mean", "stddev", "median", "min", "max" and "mad".
+<pre>let s = file.stats();
+core.log("Median value is " + s.median);</pre></li>
+</ul>
+
+<h4>FITSRecordModify</h4>
+This class is used to define modify operation FITS header in FITS and XISF files. It can remove update and add records. Order of operation is also remove then update and last add.
+The keyword names may be up to 8 characters long and can only contain uppercase letters, the digits 0-9, the hyphen, and the underscore character.
+<pre>let modify = new FITSRecordModify();
+modify.updateKeyword("OBJECT", "M42");
+modify.updateKeyword("MYTILE", "PART1", "adding custom keyword so WBPP can group it");
+modify.removeKeyword("OBJECT");
+// doesn't matter that it is specified as last. This will first remove
+// existing OBJECT record and then add again OBJECT=M42
+for(file in files)
+{
+    file.modifyFITSRecords(modify);
+}</pre>
+
+<ul>
+<li><b>new FITSRecordModify()</b> create new instance of object.</li>
+<li><b>removeKeyword(key);</b> specify removing of record with <i>key</i> as keyword.</li>
+<li><b>updateKeyword(key, value, comment = "")</b> specify updating existing keyword with value and comment. Comment is optional parameter. If record with keyword doesn't exist then it will add new one.
+        Unless you want to have multiple records with same keyword (for example HISTORY) always use this method and not addKeyword.</li>
+<li><b>addKeyword(key, value, comment = "")</b> specify adding new keyword</li>
+</ul>
