Usage
cairoUserFontFaceSetRenderGlyphFunc(font.face, render.glyph.func)
Arguments
font.face
[CairoFontFace] A user font face
render.glyph.func
[cairo_user_scaled_font_render_glyph_func_t] The render_glyph callback, or NULL
Details

The font-face should not be immutable or a CAIRO_STATUS_USER_FONT_IMMUTABLE error will occur. A user font-face is immutable as soon as a scaled-font is created from it. The render_glyph callback is the only mandatory callback of a user-font. If the callback is NULL and a glyph is tried to be rendered using font.face, a CAIRO_STATUS_USER_FONT_ERROR will occur. Since 1.8
