gboolean
gimp_rectangle_intersect (gint x1,
                          gint y1,
                          gint width1,

                          gint *dest_height);

Calculates the intersection of two rectangles.

Parameters

x1	origin of first rectangle
y1	origin of first rectangle
width1	width of first rectangle
height1	height of first rectangle
x2	origin of second rectangle
y2	origin of second rectangle
width2	width of second rectangle
height2	height of second rectangle
dest_x	return location for origin of intersection (may be `NULL`)
dest_y	return location for origin of intersection (may be `NULL`)
dest_width	return location for width of intersection (may be `NULL`)
dest_height	return location for height of intersection (may be `NULL`)

Returns

TRUE if the intersection is non-empty, FALSE otherwise
