I've found a little work-a-round to get my custom font. Here it is: from ctypes import windll gdi32 = windll.gdi32 FR_PRIVATE = 0x10 gdi32.AddFontResourceExA(FILENAME_OF_TTF,FR_PRIVATE,0) greetz Frank Am 18.05.2010 16:09, schrieb Michael Droettboom: > We went through this a few years ago on the Cairo mailing list. > The short answer is you need to copy the fonts from mpl-data to > C:\Windows\Fonts to correctly use Cairo. > > The long answer: Cairo uses fontconfig for font lookup, which by default > searches the system font directory (C:\Windows\Fonts).
