Inverting a grayscale bitmap
To reverse the colors in a grayscale bitmap, you contone the bitmap using black and white with the colors the opposite way around from normal. You can create a grayscale bitmap by doing this to a color bitmap.
To invert a grayscale bitmap
1. Select the bitmap.
2. Left-click on black on the Color Line.
3. Right-click on white on the Color Line.
Tip
Contoning isn't restricted to black and white; you can fade the colors in the bitmap between any two colors.
