intersect

Calculates the intersection of two rectangles. It is allowed for @dest to be the same as either @src1 or @src2. If the rectangles do not intersect, @dest’s width and height is set to 0 and its x and y values are undefined. If you are only interested in whether the rectangles intersect, but not in the intersecting area itself, pass %NULL for @dest.

Parameters

src1 GdkRectangle*

a #GdkRectangle

src2 GdkRectangle*

a #GdkRectangle

dest GdkRectangle

return location for the intersection of @src1 and @src2, or %NULL

Return: %TRUE if the rectangles intersect.
