This function calls cairo_set_source_rgb() for you. cr : Cairo context color : GimpRGB color Since GIMP 2.6 gimp_cairo_set_source_rgbavoid 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. cr : Cairo context color : GimpRGB color Since GIMP 2.6 gimp_cairo_set_focus_line_patterngboolean gimp_cairo_set_focus_line_pattern (cairo_t *cr, GtkWidget *widget); Sets color and dash pattern for stroking a focus line on the given cr. The line pattern is taken from widget. cr : Cairo context widget : widget to draw the focus indicator on Returns : TRUE if the widget style has a focus line pattern, FALSE otherwise Since GIMP 2.6 gimp_cairo_checkerboard_createcairo_pattern_t* gimp_cairo_checkerboard_create (cairo_t *cr, gint size, const GimpRGB *light, const GimpRGB *dark); Create a repeating checkerboard pattern. cr : Cairo context size : check size light : light check color or NULL to use the default light gray dark : dark check color or NULL to use the default dark gray Returns : a new Cairo pattern that can be used as a source on cr. Since GIMP 2.6 gimp_cairo_surface_create_from_pixbufcairo_surface_t* gimp_cairo_surface_create_from_pixbuf (GdkPixbuf *pixbuf); Create a Cairo image surface from a GdkPixbuf. You should avoid calling this function as there are probably more efficient ways of achieving the result you are looking for. pixbuf : a GdkPixbuf Returns : Since GIMP 2.6 GIMP_CAIRO_RGB24_SET_PIXEL#define GIMP_CAIRO_RGB24_SET_PIXEL(d, r, g, b) Sets a single pixel in an Cairo image surface in CAIRO_FORMAT_RGB24. d : pointer to the destination buffer r : red component g : green component b : blue component Since GIMP 2.6 GIMP_CAIRO_ARGB32_SET_PIXEL#define GIMP_CAIRO_ARGB32_SET_PIXEL(d, r, g, b, a) Sets a single pixel in an Cairo image surface in CAIRO_FORMAT_ARGB32. d : pointer to the destination buffer r : red component, not pre-multiplied g : green component, not pre-multiplied b : blue component, not pre-multiplied a : alpha component Since GIMP 2.6
