24 Transforming Image Colors
The color transformation function allows you to replace a specific image
color by another color. You can vary the range of similar colors which are
also affected by the transformation.
It also allows you to increase an image’s color saturation and to creatively
manipulate color separations.
The color transformation function cannot be applied to linework.
How to Transform Image Colors
1. Open the image (see page 20-6).
2. If you only want to transform a particular image area, create or select
a restricting mask (see page 22-13).
3. Press F12 or select IMAGE | COLOR TRANSFORMATION.
4. Proceed as described in the following sections:
Replacing Source Color by Target Color (page 24-2)
Changing Color Saturation (page 24-4)
Manipulating Image Color Separations (page 24-4)
Transforming Colors by Direct Parameter Input (page 24-8)
5. You can compare the modified image with the original. To do so, use
the toggle function SHOW BEFORE or press F4.
Note:
6. When finished, press RETURN/ENTER or click .
If only a section of an image is loaded, you can only modify this section.
