IMB_rectfill()

void IMB_rectfill	(	ImBuf *	drect,

Parameters

drect	An image to be filled with color. It must be 4 channel image.
col	RGBA color, which is assigned directly to both byte (via scaling) and float buffers.

		const float	scene_linear_color[4],
		int	x1,

		int	y2 )

Blend pixels of image area with solid color.

Parameters

ibuf	an image to be filled with color. It must be 4 channel image.
scene_linear_color	RGBA color in scene linear colorspace. For byte buffers, this is converted to the byte buffer colorspace.
x1,y1,x2,y2	(x1, y1) defines starting point of the rectangular area to be filled, (x2, y2) is the end point. Note that values are allowed to be loosely ordered, which means that x2 is allowed to be lower than x1, as well as y2 is allowed to be lower than y1. No matter the order the area between x1 and x2, and y1 and y2 is filled.
colorspace	color-space reference for display space.
