示例

 

' ========================================================================================

' The following example creates a linear gradient brush and uses it to fill a rectangle.

' Next, the code sets the brush's transformation matrix, fills a rectangle with the

' transformed brush, resets the brush's transformation matrix, and fills a rectangle with

' the untransformed brush.
