PushTransparencyLayer メソッド (GcGraphics)

DS.Documents.Imaging アセンブリ > GrapeCity.Documents.Drawing 名前空間 > GcGraphics クラス : PushTransparencyLayer メソッド
The content bounds of the transparency layer. Content won't render outside these bounds. When set to null 参照 (Visual Basicでは Nothing), the content bounds are effectively taken to be the bounds of the current graphics.
An opacity value that is applied uniformly to all drawings in the layer when compositing to the backplate.
Adds a transparency layer to the current graphics. That layer receives all subsequent drawing operations until PopTransparencyLayer is called.
