Abstract

Pixel data is stored in a data field corresponding to a pixel of an image. The data field includes an opacity bit, a first set of bits, and a second set of bits. If the opacity bit is set to an opaque-indicating state, then a color level value of a first component color of the pixel is stored in the first set of bits and a color level value of a second component color of the pixel is stored in the second set of bits. However, if the opacity bit is set to a transparency-indicating state, then a transparency level value is stored in at least one bit of each set, of the first and second sets, of bits and the respective color level value is stored in other bits of each set, of the first and second sets, of bits.
