Description

Call IsRectEmpty to determine whether the rectangle specified by Rect encloses a positive amount of space.

IsRectEmpty returns true if both the width and height of Rect are greater than 0. If either the width or height is less than or equal to 0, IsRectEmpty returns false. Note that this means non-normalized rectangles (rectangles with negative height or width) are considered empty.
