Subject: GetGlyphID in PoDoFo
To: "podofo-users@lists.sourceforge.net" <podofo-users@lists.sourceforge.net

I am having trouble getting the PdfFontMetrics::GetGlyphID(long lunicode)
function to work. I have pasted some very simplified code below. For the
current font some functions are working as shown below. For example I can
successfully get the Char Width and Font Size for each character but for
some reason not the Glyph ID. I am using the latest version on the Podofo
website 0.9.3 but am having trouble with the subversion link (i'm using SV
Tortoise to download the files. Could it be that this issue has already
been fixed with a patch that is only incorporated in the latest SVN version?
Could someone please test my code below and maybe indicate what I have done
wrong here? If you look down to the inline comment
"// NOW ATTEMPT TO EXTRACT GLYPH INFORMATION" just below that is where I
have applied the GetGlyphID method. Thanks
