I have a JPEG image that needs its colors changed before I use it in an Apache OpenOffice file. How do I change the colors?

When you open a JPEG file, Apache OpenOffice displays the image toolbar just below the command bar. Once the file is open:

1. Select: Tools → Eyedropper from the Menu bar. It will display a floating window called Eyedropper.
2. Click the Eyedropper icon (uppermost top left icon).
3. Enter a tolerance value to define how exact the color match should be. First try a tolerance of 10%. You might need to increase it for any change to be visible. A 30% value is usually effective. You can go as high as 99%, but it may pick up more area than you want.
4. Select in the image the color you want to change. In the eyedropper floating window, that color will be automatically selected.
5. Choose the new color you wish to use from the Replace with drop down list.
6. Click the  Replace  button to confirm your choice. If nothing happens, increase the tolerance.
7. To replace more colors, select another color rectangle to the left of the Eyedropper floating window, then repeat the steps from 2 to 5. Finally, confirm your choices by clicking the  Replace  button.
