To permanently change the values of the image's palette, you can modify the RGB values at a specified index in the image's stored palette, as follows:

1. Set ProcessImageID property to the image you wish to query or modify.
2. Call DIBGetPalIndex and DIBSetPalIndex to get and set the RGB value for a specified palette entry in the image's palette.   

The Undo method does not undo changes to the image palette.

It is also possible to apply a different palette to the display or print DC without modifying the image's palette. See Display Image and Print an Image for more information.
