GrapeCity.Documents.Imaging アセンブリ > GrapeCity.Documents.Imaging 名前空間 > GcBitmap クラス : AlphaBlend メソッド
The source bitmap.
The x-coordinate, in pixels, of the upper-left corner of the destination rectangle.
The y-coordinate, in pixels, of the upper-left corner of the destination rectangle.
The affected rectangle of the destination GcBitmap.
The opacity [0, 1] of the source bitmap, to multiply to the source bitmap's alpha channel.
The width, in pixels, of the source and destination rectangles.
The height, in pixels, of the source and destination rectangles.
The x-coordinate, in pixels, of the upper-left corner of the source rectangle.
The y-coordinate, in pixels, of the upper-left corner of the source rectangle.
Draws the source bitmap with the specified opacity into the current bitmap.
