| PaintImageRegionEffect(Graphics,RasterImage,Rectangle,Rectangle,Rectangle,Rectangle,RasterPaintProperties,SpecialEffectsType,SpecialEffectsProgress) |
Applies an effect when painting a bitmap region to a device context. This method works the same as PaintImageEffect, except that only the bitmap region is painted. |
| PaintImageRegionEffect(IntPtr,RasterImage,Rectangle,Rectangle,Rectangle,Rectangle,RasterPaintProperties,SpecialEffectsType,SpecialEffectsProgress) |
Applies an effect when painting a bitmap region to a device context. This method works the same as PaintImageEffect, except that only the bitmap region is painted. |
