Additional Comments

Use the lockColorMap property to trade off between color accuracy and possible screen flashing when the bit depth of the screen is 8 bits (256 colors) or less.

Value:

The lockColormap is true or false.

By default, the lockColorMap property is set to true on Mac OS systems with 8-bit displays (the screenColors equal to 256), and to false otherwise.

Comments:

If the lockColorMap property is set to false, newly-displayed images, videoclips, and players can change the color table used by Revolution. This displays the colors in images and movies more accurately, but can cause screen flashing. (To minimize screen flashing when the lockColorMap is false, go to the card containing the image and then set the lockColorMap property to true.)

If the lockColorMap is true, the color table cannot be changed. In this case, if an image, video clip, or player contains a color not in the current color table, the closest existing color is substituted. This may cause banding or strange-looking displays in photographs and other images that contain a smooth gradation of colors.

This property has no effect on systems using 16-bit or 24-bit color.
