Member Function Documentation

void PoDoFo::PdfFontTTFSubset::AddCharacter ( pdf_utf16be  nCharCode) [inline]

Add an unicode character to the subset

Parameters:
nCharCodeunicode character code
void PoDoFo::PdfFontTTFSubset::AddGlyph ( unsigned short  nGlyphIndex)

Parameters:
nGlyphIndexinclude this glyph in the final font

Already existing values are ignored, so that every glyph can be added only once.

Actually generate the subsetted font

Parameters:
pOutputDevicewrite the font to this device
