| Make changes to the Alpha channel of information in the image. | AddAlpha Method GetAlphaCopy Method GetAlphaDIBInfo Method RemoveAllAlpha Method RemoveAlpha Method |

| Make changes to the resolution "metadata" stored with the image (changing this does not resize the image, only redefines the volume of physical space that each image pixel represents). | GetImageResolutionCopy Method |
