Recently I had some minor issues with converting Qtf to Pdf in server environment. Surely, it was not that hard, but I guess dircet support is better. So it inspired two new functions:
Array<Drawing> RenderPages(const RichText& txt, Size pagesize = Size(3968, 6074));
String Pdf(const RichText& txt, Size pagesize = Size(3968, 6074), int margin = 200, bool pdfa = false);
The harder part here is RenderPages, Pdf is then only simply call to PdfDraw package, using RenderPages.
Qtf->Pdf is then just matter of:
#include <RichText/RichText.h>
using namespace Upp;
CONSOLE_APP_MAIN
{
SaveFile(GetHomeDirFile("test.pdf"), Pdf(ParseQTF("[A9 Hello World!")));
}

BTW... is there any way to import PDF files as QTF?

Unfortunately, no, for two reasons:
PDF is basically vector graphics format, while QTF is rich text format - they are not even meant to express the same thing. QTF->PDF is something like typesetting glyphs into graphics.
Means, PDF could only be rendered into something graphical. Painter (and Painting) would be a good target for that, as it matches PDF quite well. Unfortunately, nobody cared to write that code so far, and for a good reason too - PDF is quite complicated.
Note that basically the same thing applies to SVG too, in that case we do yet have QTF->SVG path yet. In fact, we are missing Painter->PDF and Painter->SVG etc... too  It is planned in general roadmap, but too costly to implement (I think about 1 month for Painter->PDF, Painter->SVG, 2 months for SVG->Painter, more for PDF->Painter).
