Parameters

color

Specifies the color to use for the region.

combineMode

The action to take regarding the existing image region, if one is defined.

You can use this method to simulate the use of a transparent color as follows:

1. Call AddColorToRegion, with the transparent color in the color parameter and RasterRegionCombineMode.SetNot in the combineMode parameter.
2. Call PaintRegion to paint the resulting region, which includes everything in the image, except the transparent color.

To update an existing region, you specify how the new region is to be combined with the existing one using the combineMode parameter. For more information, refer to RasterRegionCombineMode.
