cairo_surface_t* go_marker_create_cairo_surface
(GOMarker const *marker,

Creates a new cairo surface similar to the current target of cr, and render
marker on it. center will contain the coordinate of the center of the surface.
marker : |
a GOMarker |
cr : |
a cairo context |
scale : |
current context scale |
width : |
a placeholder for the surface width |
height : |
a placeholder for the surface height |
| Returns : | a newly created cairo_surface_t. This surface should be destroyed using cairo_surface_destroy after use. |
void go_marker_render (GOMarker const *marker,
cairo_t *cr,
double x,
double y,
double scale);
Renders marker onto the cairo target, using x and y for the position.
marker : |
a GOMarker |
cr : |
a cairo context |
x : |
x position |
y : |
y position |
scale : |
current scale |
GtkWidget* go_marker_selector_new (GOMarkerShape initial_shape, GOMarkerShape default_shape);
Creates a new marker selector.
initial_shape : |
marker shape intially selected |
default_shape : |
automatic marker shape |
| Returns : | a new GtkWidget. |
