void gimp_cairo_set_source_rgb (cairo_t *cr
,const GimpRGB *color
);
Sets the source pattern within cr
to the solid opaque color
described by color
.
This function calls cairo_set_source_rgb()
for you.
Since: 2.6
void gimp_cairo_set_source_rgba (cairo_t *cr
,const GimpRGB *color
);
Sets the source pattern within cr
to the solid translucent color
described by color
.
This function calls cairo_set_source_rgba()
for you.

const Babl *
gimp_cairo_surface_get_format (cairo_surface_t *surface
);
This function returns a Babl format that corresponds to surface
's
pixel format.
Since: 2.10
GeglBuffer *
gimp_cairo_surface_create_buffer (cairo_surface_t *surface
);
This function returns a GeglBuffer which wraps surface
's pixels.
It must only be called on image surfaces, calling it on other surface
types is an error.
Since: 2.10
