cairo_set_font 3 cairo_set_font replace the font in the current state void cairo_set_font (cairo_t *cr, cairo_font_t *font) cr : a cairo_t font : a cairo_font_t functions cairo_set_font Replaces the current cairo_font_t object in the cairo_t with font. The replaced font in the cairo_t will be destroyed if there are no other references to it. Since a cairo_font_t is specific to a particular output device and size, changing the transformation, font transformation, or target surfaces of a cairo_t will clear any previously set font. Setting the font using cairo_set_font is exclusive with the simple font selection API provided by cairo_select_font. The size and transformation set by cairo_scale_font() and cairo_transform_font() are ignored unless they were taken into account when creating font.
