1 Zoom in on the image so you can accurately select the color.

2 Select the image, then right-click ➤ Properties.

NOTE If you are zoomed so you cannot see the image frames, press Shift +
left-click to select the image.

3 Click the Transparency Color property, then click the button in the

property field.

The Transparency Color dialog box is displayed.

NOTE Selecting a color is necessary only for color and grayscale images. To
make a bitonal image transparent, skip to step 7.

4 Click Select.

The cursor changes shape and the dialog box temporarily disappears so
that you can choose a color from the image.

5 Pick the desired color on the image, and click OK.

6 Click the Transparency property, then select Yes from the list to make

the color you just selected transparent.

If you want to use the color for rubbing and cropping but you also want
the color displayed in the image, select No for Transparency.

NOTE Changing the transparency color does not affect the color of the
existing rubs and crops.

7 Close the Properties dialog box.

The rbackground command allows you to designate an unused color as the
transparency color.

This is especially useful for merging images in which the designated
transparency color in one image may cause valuable pixels in the other image
to become transparent.
