+<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>
+</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>
+
+<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>
+
+<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.
+<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>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>
+</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>
+
+<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>
