Make a color transparent (Create Bitmap Copy)

(Up to 256-color formats only)

These formats can have transparent areas in the bitmap. This is done by making one of the entries in the color palette a special "transparent" color. (So a 16-color bitmap with transparency contains 15 colors plus transparency.)

To make a color transparent

1. The Create Bitmap Copy dialog box displays the bitmap palette. (Color Depths up to 256-color only.) Click on a color to select it.

2. Click the Make transparent button. A small square appears in the top left of the color to tell you it is transparent. Any parts of the bitmap that use this color become transparent.

Notes:

You can make multiple palette entries transparent.

There is a more advanced type of graduated transparency called "alpha-channel" rather than this simple on-off transparency. True-color with alpha-channel transparency is an option on the Color depth list on the Create Bitmap Copy dialog box.

For more information on the Create Bitmap Copy dialog box click the Help button on this dialog box.

You can also select a color using the Color Selector (the "eye-dropper"). Click on the required color in the Preview window.
