Replacing Colors
You can replace colors in bitmaps with the \<emph\>Eyedropper\</emph\> tool.
Up to four colors can be replaced at once.
You can also use the \<emph\>Transparency\</emph\> option to replace the transparent areas of an image with a color.
Similarly, you can use the \<emph\>Eyedropper\</emph\> to make a color on your image transparent.
To replace colors with the Eyedropper tool
Ensure that the image you are using is a bitmap (for example, BMP, GIF, JPG, or PNG) or a metafile (for example, WMF).
-
Choose \<emph\>Tools - Calculate\</emph\>
-
Click the Eyedropper icon and position the mouse pointer over the color you want to replace in the image. The color appears in the box next to the eyedropper icon.
-
Click the color in the image. The color appears in the first \<emph\>Source color\</emph\> box and the check box next to the color is selected.
-
In the \<emph\>Replace with\</emph\> box, select the new color.
This replaces all occurrences of the \<emph\>Source color\</emph\> in the image.
-
If you want to replace another color while the dialog is open, select the check box in front of \<emph\>Source color\</emph\> in the next row and repeat steps 3 to 5.
-
Click \<emph\>Replace\</emph\>.

If you want to expand or contract the color selection area, increase or decrease the tolerance of the \<emph\>Eyedropper\</emph\> tool and repeat your selection.
