+<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 bit integer and 32 bit float</li>
+    <li>XISF 8, 16 bit integer and 32 bit float</li>
+    <li>JPEG and PNG images</li>
+    <li>CR2, 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 5 buttons for automatic stretching:
+<ul>
+    <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>Super pixel CFA </i> average 2x2 pixels into one (suitable for images from colour camera).</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".

+<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 et PNG</li>
+    <li>images RAW CR2, 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".

+<h2>Tenmon pomocník</h2>
+
+<p>Tenmon slúži primárne na zobrazenie astronomických fotiek a obrázkov. Dokáže otvoriť nasledovné formáty:
+<ul>
+    <li>FITS 8, 16 bitové celočíselné a 32 bitové s plávajúcou čiarkou</li>
+    <li>XISF 8, 16 bitové celočíselné a 32 bitové s plávajúcou čiarkou</li>
+    <li>JPEG a PNG obrázky</li>
+    <li>CR2, 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>
+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.
+Super pixel CFA spriemeruje dva krát dva pixeli do jedného čo je vhodné pri prezeraní surových obrázkov z farebných kamier.
+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.
+Pre odznačenie je treba držať <i>Ctrl</i></p>
+
+<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.
+<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>
