Re: Edit ColorMap
Above, Clo has answered correctly.
Some addition:
The menu entry is only available if your image is an image with a colour palette. Colour palette images have up to 256 different colours, each colour (value) stored in the image's colour palette.
In order to convert a non-colour palette image (e.g. true colour or grey scale) to a colour palette image you use "Image > Convert to colours..." and then choose the number of colours (256 recommended). Please note that reducing an image to 256 different colours often results in colour distortions and visible gradiations.
