> How can I check from my C++ program that a font is a TrueType font?
What do you mean by ``font''? A font file, an X11 core font instance,
a FontConfig FcPattern or an XftFont, or something else?
TrueType font files have a signature in the first four bytes. These
bytes should be
00 01 00 00 for a TrueType font;
4F 54 54 4F for an OpenType/CFF font.
(OpenType/TTF is just another name for TrueType.)
If it's a core font instance you want to know about (a thingie
returned by XLoadFont), check for the value of the property FONT_TYPE.
If it's an FcPattern you want to look at, check the value of the
If it's an XftFont, a g_font, a Qt font, or something else, I've got no idea.
