Object getPersistDocument();
Add an EOT font to the slideshow. An EOT or MTX font is a transformed True-Type (.ttf) or Open-Type (.otf) font. To transform a True-Type font use the sfntly library (see "see also" below)

(Older?) Powerpoint versions handle embedded fonts by converting them to .ttf files and put them into the Windows fonts directory. If the user is not allowed to install fonts, the slideshow can't be opened. While the slideshow is opened, its possible to copy the extracted .ttfs from the fonts directory. When the slideshow is closed, they will be removed.

Params:
  • fontData – the EOT font as stream
Throws:
  • IOException – if the fontData can't be saved or if the fontData is no EOT font
See Also:
Returns:the font info object containing the new font data
