Declaration [src]
void
clutter_paint_node_add_rectangles (
ClutterPaintNode* node,
const float* coords,
unsigned int n_rects
)
Description [src]
Adds a series of rectangles to node
.
As a general rule for better performance its recommended to use this API
instead of calling clutter_paint_node_add_rectangle()
separately for
multiple rectangles if all of the rectangles will be drawn together.
See cogl_framebuffer_draw_rectangles().
Parameters
coords |
An array of float |
Array of coordinates containing groups of 4 float values: [x_1, y_1, x_2, y_2] that are interpreted as two position coordinates; one for the top left of the rectangle (x1, y1), and one for the bottom right of the rectangle (x2, y2). |
|
The length of the array is specified in the n_rects argument. | |
The data is owned by the caller of the function. | |
n_rects |
unsigned int |
