Function Documentation

BLI_rctf_clamp()

bool BLI_rctf_clamp	(	rctf *	rect,
		const rctf *	rect_bounds,
		float	r_xy[2]
	)

Clamp rect within rect_bounds, setting r_xy to the offset.

Keeps the top left corner within the bounds, which for user interface elements is typically where the most important information is.

Returns

true if a change is made.

BLI_rctf_is_valid()

bool BLI_rctf_is_valid

(

)

Check if X-min and Y-min are less than or equal to X-max and Y-max, respectively. If this returns false, BLI_rctf_sanitize() can be called to address this.

This is not a hard constraint or invariant for rectangles, in some cases it may be useful to have max < min. Usually this is what you'd want though.
