Hello,
it is possible, only note that PoDoFo doesn't render anything, it only
writes rendering instructions to a PDF file, which a reader
(Adobe/evince/......) interprets.
I cannot give you exact code, I do not have it handy, but I can provide
a rough overview (maybe it'll not be accurate):
- attach your (newly created?) font to the PDF;
- create a mapping between 'char' codes to glyph IDs, which can be done
with a PdfEncoding descendant (there can be sometimes involved
PdfEncodingDifference, but it sounds like it's not what you want);
- then create a PdfFont with that PdfEncoding descendant used (the
GetFont() variants have the PdfEncoding * argument);
- then print the letters according to your mapping.
The hardest part will be to describe the font properly, with its
'letter' widths and so on, but I think the freetype can read that from
the font description and PoDoFo can use that information for you.
Hope it helps,
zyx
P.S.: As you target Windows, it would be interesting to know whether
litePDF can handle it for you. I'm just being curious. :)
