Combiner Class

Syntax

Public NotInheritable Class Combiner _
	Inherits MaskedBitmapTransform

public sealed class Combiner : MaskedBitmapTransform

Remarks

Two bitmaps are involved into this transform:

1. "Upper" image, or source bitmap. Pixels are taken from it. You specify it using SourceBitmap property.
2. "Lower" image, or destination bitmap. Pixels are combined with it. This bitmap is retrieved into ApplyTransform(Bitmap) method.

Bitmaps can be combined in the different way: just copying pixels from one bitmap to another, alpha blending, bitwise operations, etc. You can adjust it with CombineMode property. Property Opacity specifies a total opacity of the SourceBitmap.

If you need to take source bitmap pixels only partially, you can specify rectangular area using SourceRectangle property. In the same way you can specify an area of the destination bitmap where to put the pixels using DestinationRectangle property. By default both rectangles equals to the size of the source bitmap. If rectangles differs, this transform resizes a block of pixels taken from SourceRectangle to have the same size as DestinationRectangle. Using InterpolationMode property you can manage interpolation quality/speed.
