+@mainpage The Poppler Qt6 interface library
+
+The %Poppler Qt6 interface library, libpoppler-qt6, is a library that
+allows Qt6 programmers to easily load and render PDF files. The
+%Poppler Qt6 interface library uses poppler internally to do its job,
+but the Qt6 programmer will never have to worry about poppler
+internals.
+
+
+@section help Current Status
+
+The %Poppler Qt6 interface library is quite stable and working.
+
+@section refimpl Example Programs
+
+Examples programs can be found in the qt6/test directory. The %Poppler
+Qt6 interface library is also used in the KDE's
+document viewer <a href="http://okular.kde.org">Okular</a>. The source files
+for Okular's PDF plugin (%Poppler-based) can be found on the git server
+of the KDE project, under
+<a
+href="http://quickgit.kde.org/?p=okular.git&a=tree&f=generators/poppler">this
+URL</a>.
+
+
+@section req How to use the Poppler Qt6 interface library in three easy steps
+
+Programmer who would like to use the %Poppler Qt6 interface library
+simply need to add the following line to their C++ source files:
+
+@code
+#include <poppler-qt6.h>
+@endcode
+
+
+For using the Qt6 interface on Android, there is an additional step - you must place the following font files in the assets/share/fonts directory of the Android APK:
+
+ - NimbusMonoPS-Regular.otf
+ - NimbusMonoPS-Bold.otf
+ - NimbusMonoPS-BoldItalic.otf
+ - NimbusMonoPS-Italic.otf
+ - NimbusSans-Regular.otf
+ - NimbusSans-Bold.otf
+ - NimbusSans-BoldItalic.otf
+ - NimbusSans-Italic.otf
+ - StandardSymbolsPS.otf
+ - NimbusRoman-Bold.otf
+ - imbusRoman-BoldItalic.otf
+ - NimbusRoman-Italic.otf
+ - NimbusRoman-Regular.otf
+ - D050000L.otf
+
+These are used as substitute fonts for the base-14 fonts, and this step is required in order to reliably display documents with unembedded fonts. You can easily find these font files included within GhostScript.
+
+A PDF document can then be loaded as follows:
+@code
+QString filename;
+
+Poppler::Document* document = Poppler::Document::load(filename);
+if (!document || document->isLocked()) {
+
+ // ... error message ....
+
+ delete document;
+ return;
+}
+@endcode
+
+Pages can be rendered to QImages with the following commands:
+
+@code
+// Paranoid safety check
+if (document == 0) {
+ // ... error message ...
+ return;
+}
+
+// Access page of the PDF file
+Poppler::Page* pdfPage = document->page(pageNumber); // Document starts at page 0
+if (pdfPage == 0) {
+ // ... error message ...
+ return;
+}
+
+// Generate a QImage of the rendered page
+QImage image = pdfPage->renderToImage(xres, yres, x, y, width, height);
+if (image.isNull()) {
+ // ... error message ...
+ return;
+}
+
+// ... use image ...
+
+// after the usage, the page must be deleted
+delete pdfPage;
+@endcode
+
+Finally, don't forget to destroy the document:
+
+@code
+delete document;
+@endcode
+ */
