◆ IMB_rectfill()

void IMB_rectfill	(	ImBuf *	drect,

col	RGBA color, which is assigned directly to both byte (via scaling) and float buffers.

		const float	col[4],
		int	x1,

		int	x2,
		int	y2,
		struct ColorManagedDisplay *	display
	)

Blend pixels of image area with solid color.

For images with uchar buffer use color matching image color-space. For images with float buffer use color display color-space. If display color-space can not be referenced, use color in SRGB color-space.

Parameters

ibuf	an image to be filled with color. It must be 4 channel image.
col	RGBA color.
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.
display	color-space reference for display space.

		const float	col[4],
		int	x1,
		int	y1,
		int	x2,
		int	y2
	)

Replace pixels of image area with solid color.

Parameters
