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.)

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:

image\BULLET.gif You can make multiple palette entries transparent.

image\BULLET.gif 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.
