This tool is designed to intelligently weigh the pixel colors of the selection or active layer and reduce the number of colors while maintaining a semblance of the original image characteristics.
You can get to this tool in several ways:
In the image menu through
→ → or → .
By clicking on the tool icon
in Toolbox, if this tool has been installed there. For this, please
refer to Secció 1.7, «Caixa d'eines».
This slider and the input boxes with arrow-heads allow you to set the number of levels (2-256) in each RGB channel that the tool will use to describe the active layer. The total number of colors is the combination of these levels. A level to 3 will give 23 = 8 colors.
The Preview check-box makes all changes dynamically so that they can be viewed straight away.
