Working with colors in bitmaps
Corel DESIGNER lets you change colors in monochrome images, hide and show colors, and mask colors. Monochrome bitmaps have two
colors: black and white. You can replace the black and white pixels with any color on a color palette.
You can hide and display selected colors by masking them. Hiding colors in a bitmap lets objects or backgrounds show through the image.
Hiding a color can also alter the apparent shape of a bitmap. For example, if a bitmap shows a person on a black background, you can
hide the background so that the bitmap appears to take on the shape of the person rather than a rectangular shape. Also, hiding colors in
bitmaps can increase the speed at which objects are rendered on the screen. You can also display certain colors in a bitmap to change the
appearance of the image or to see where a particular color has been applied. You can mask as many as 10 colors in a bitmap.
Color masking also lets you change selected colors without altering the other colors in an image. You can also save a bitmap color mask to a
file and open the file for future use.
