Use this menu option to reduce the number of colours in the artwork on a selected bitmap layer.
ArtCAM takes colours of a similar shade in the artwork and produces an averaged colour from them. The averaged colour replaces the originals.
Note: The
Reduce Colours

button on the
Bitmap Tools toolbar is a shortcut for this menu option. The availability of this button and toolbar is license dependent
Reducing the number of colours helps to:
- remove unwanted colours.
- control the number of vectors created when converting bitmap artwork.
- control the shape of vectors created when converting bitmap artwork.
- control the size of 3D shapes.
Note: Colour reduction should be done as an iterative process so the number of colours can be minimised while preserving the detail in the original bitmap artwork.
Reducing the number of colours in the bitmap artwork resets all colour links and shape attributes.
To reduce the number of colours on a bitmap layer:
- In the Project Tree, select the bitmap layer.
- Select
Bitmap > Colour > Reduce Number or click
. The
Reduce Colours dialog is displayed.
- Move the slider, or enter a
New maximum number of colours for image value between 2 and the
Current number of colours in image value.
- Click
Apply.
