BlurChannel
BlurChannel(srcImage, destImage, radius, doAlpha, doRed, doGreen, doBlue, aspect)
Additional Notes
There doesn't appear to be any significant difference in speed between BlurChannel and Blur. Choosing to blur only specific channels does not appear to save any processing time over blurring all channels.
BlurChannel allows for selective blurring of specific channels in an image. SrcImage, destImage, radius and aspect are the same as the basic Blur function.
DoAlpha, doRed, doGreen and doBlue are boolean switches which tell BlurChannel whether to process those channels or not. Boolean values are either off or on, represented by a 0 or a 1 (or true/false). To blur only the alpha channel from the image in src1 to dest, the code would look like this:
BlurChannel(src1, dest, radius, 1, 0, 0, 0, Aspect)
