Method
CoglFramebufferpush_primitive_clip
Declaration [src]
void
cogl_framebuffer_push_primitive_clip (
CoglFramebuffer* framebuffer,
CoglPrimitive* primitive,
float bounds_x1,
float bounds_y1,
float bounds_x2,
float bounds_y2
)
Description [src]
Sets a new clipping area using a 2D shaped described with a
CoglPrimitive
. The shape must not contain self overlapping
geometry and must lie on a single 2D plane. A bounding box of the
2D shape in local coordinates (the same coordinates used to
describe the shape) must be given. It is acceptable for the bounds
to be larger than the true bounds but behaviour is undefined if the
bounds are smaller than the true bounds.
The primitive is transformed by the current model-view matrix and
the silhouette is intersected with the previous clipping area. To
restore the previous clipping area, call
cogl_framebuffer_pop_clip()
.
