Parameters

underlayImage

The image that will be used as the underlying image. This is the image that appears to be on bottom and is grayscaled as it is combined with the target image.

flags

Indicators of how the underlying image is to be positioned.

This is most effective when the underlying image is a filtered one, such as an embossed image.

This method changes the colors of the underlay to grayscale as it combines the images. It updates this RasterImage, leaving the underlayImage unchanged. underlayImage can either be stretched or tiled to fill the image, as shown in the following illustration:
