Mapping a Gradient to
Luminance in an Image
You can map a gradient to an existing
image, replacing an image’s colors
with those of the gradient. This effect
applies gradient colors to the pixels of
the image, based on their luminance
values.
Corel Painter allows you to apply a gradient
based on the luminance value of existing
colors.
To express a gradient in an image:
1 Open the image you want to use.
Select part of the image or use the
entire image.
2 Choose Window menu > Show
Gradients
to display the Gradients
palette.
3 Select the gradient you want to
use.
4 Click the palette menu arrow, and
choose Express in Image.
5 In the Express in Image dialog
box, adjust the Bias slider to define
how the gradient is mapped.
Corel Painter replaces the colors in
the image with the colors in the
gradient, based on matching
luminance.
