How the palette is determined

When you load a raster image with a color depth of two, 16 or 256 Scan2CAD automatically creates a default palette that includes all the colors on the image.

You can change this palette using Palette Menu > Select Palette.

 

When you load a raster image with a color depth of 16.7 million no palette is created until you use one of the following functions:

Palette Menu > Reduce Color Depth

Scan2CAD creates a palette containing the number of colors you have specified, based on the color distribution within the image.  It then maps all of the other colors in the image to the colors in the palette. The image’s color depth is reduced to the number of colors you specified.

Palette Menu > View/Edit Palette

Scan2CAD creates a palette of 256 colors, based on the color distribution within the image. It then maps all of the other colors in the image to the 256 colors in the palette. The image’s color depth is retained at 16.7 million but it now only uses 256 of the 16.7 million colors.

Palette Menu > Reduce Colors Auto

Scan2CAD creates a palette containing the number of colors you have specified, based on the color distribution within the image.  It then maps all of the other colors in the image to the colors in the palette. The image’s color depth is retained at 16.7 million but it now only uses the number of colors you specified.

Palette Menu > Select Palette

 Scan2CAD maps all the colors in the image to the colors in the selected palette. The image’s color depth is retained at 16.7 million but it now only uses the colors in the palette.
