Functions
| void | cogl_clip_push_rectangle () |
| void | cogl_clip_push_window_rectangle () |
| void | cogl_clip_pop () |
Description
To support clipping your geometry to rectangles or paths Cogl exposes a stack based API whereby each clip region you push onto the stack is intersected with the previous region.
Functions
cogl_clip_push_rectangle ()
void cogl_clip_push_rectangle (float x0,float y0,float x1,float y1);
cogl_clip_push_rectangle has been deprecated since version 1.16 and should not be used in newly-written code.
Use cogl_framebuffer_push_rectangle_clip()
instead
Specifies a rectangular clipping area for all subsequent drawing operations. Any drawing commands that extend outside the rectangle will be clipped so that only the portion inside the rectangle will be displayed. The rectangle dimensions are transformed by the current model-view matrix.
The rectangle is intersected with the current clip region. To undo
the effect of this function, call cogl_clip_pop().
Parameters
x0 |
x coordinate for top left corner of the clip rectangle |
|
y0 |
y coordinate for top left corner of the clip rectangle |
|
x1 |
x coordinate for bottom right corner of the clip rectangle |
|
y1 |
y coordinate for bottom right corner of the clip rectangle |
Since: 1.2
cogl_clip_push_window_rectangle ()
void cogl_clip_push_window_rectangle (int x_offset,int y_offset,int width,int height);
cogl_clip_push_window_rectangle has been deprecated since version 1.16 and should not be used in newly-written code.
Use cogl_framebuffer_push_scissor_clip() instead
Specifies a rectangular clipping area for all subsequent drawing operations. Any drawing commands that extend outside the rectangle will be clipped so that only the portion inside the rectangle will be displayed. The rectangle dimensions are not transformed by the current model-view matrix.
The rectangle is intersected with the current clip region. To undo
the effect of this function, call cogl_clip_pop().
Parameters
x_offset |
left edge of the clip rectangle in window coordinates |
|
y_offset |
top edge of the clip rectangle in window coordinates |
|
width |
width of the clip rectangle |
|
height |
height of the clip rectangle |
Since: 1.2
cogl_clip_pop ()
void
cogl_clip_pop (void);
cogl_clip_pop has been deprecated since version 1.16 and should not be used in newly-written code.
Use cogl_framebuffer_pop_clip() instead
Reverts the clipping region to the state before the last call to
cogl_clip_push().
