In image correction, the white point determines the brightness value that is considered white in a bitmap image. In Corel PHOTO-PAINT, you
can set the white point to improve the contrast of an image. For example, in a histogram of an image, with a brightness scale of 0 (dark) to
255 (light), if you set the white point at 250, all pixels with a value greater than 250 are converted to white.
