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.
Since: 2.6
cairo_pattern_t * gimp_cairo_checkerboard_create (cairo_t *cr,gint size,const GimpRGB *light,const GimpRGB *dark);
Create a repeating checkerboard pattern.
Since: 2.6
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
#define GIMP_CAIRO_RGB24_SET_PIXEL(d, r, g, b)
Sets a single pixel in an Cairo image surface in CAIRO_FORMAT_RGB24.
Since: 2.6
#define GIMP_CAIRO_RGB24_GET_PIXEL(s, r, g, b)
Gets a single pixel from a Cairo image surface in CAIRO_FORMAT_RGB24.
Since: 2.8
#define GIMP_CAIRO_ARGB32_SET_PIXEL(d, r, g, b, a)
Sets a single pixel in an Cairo image surface in CAIRO_FORMAT_ARGB32.
