public:
void SetNumEdgePixels(
	int nb
)

member SetNumEdgePixels : 
        nb : int -> unit 

Parameters

nb

Type: SystemInt32

The default value is two pixels. Some overlap is usually required to avoid visual "artifacts" at the subimage boundaries. One source of artifacts is that when OpenGL clips lines, it draws a line between the points where the line exits and re-enters the visible region. This additional segment is not part of the actual geometry. A two pixel overlap will hide this undesired segment unless the line width is greater than two, in which case you may need to specify a larger overlap.
