Method

ClutterPaintNodeadd_rectangles

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

Type: 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 method.

n_rects

Type: unsigned int

Number of rectangles defined in coords.
