This command will remove the alpha information from an image by blending the transparent areas with a solid color.
Use this command to invert the image.
This command allows you to replace the channels of an existing image by substituting the channel values with those of an 8-bit grayscale image.
This command will create an alpha channel for an image based on a color value. If the image already contains alpha information, the color will be blended into it.
Creates an alpha channel for an image using an 8-bit grayscale mask image to control transparency.
This command will create an alpha channel based on a numeric value.
This command will shift individual image channels.
Swaps one channel with another channel within the same image.
