Member Function Documentation

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

Add an unicode character to the subset

Parameters:
nCharCode unicode character code

void PoDoFo::PdfFontTTFSubset::AddGlyph ( unsigned short  nGlyphIndex  ) 

Add a new glyph index to the subset.

Parameters:
nGlyphIndex include this glyph in the final font
Already existing values are ignored, so that every glyph can be added only once.

void PoDoFo::PdfFontTTFSubset::BuildFont ( PdfOutputDevice pOutputDevice  ) 

Actually generate the subsetted font

Parameters:
pOutputDevice write the font to this device
