Abstract
Pixel data is stored in a field corresponding to a pixel of an image. The field includes an opacity bit and a set of bits. If the opacity bit is set to an opaque-indicating state, then a color level value of a component color of the pixel is stored in the 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 the set of bits and the respective color level value is stored in other bits of the set of bits.
Claims10
A method for storing pixel data in a field corresponding to a pixel of an image, the field including an opacity bit and a set of bits, the method comprising the following actions implemented by a microprocessor:
- storing a color level value of a component color of the pixel in the set of bits if the opacity bit is set to an opaque-indicating state;
- and
- storing a transparency level value in at least one bit of the set of bits and storing the respective color level value in other bits of the set of bits if the opacity bit is set to a transparency-indicating state.
A non-transitory computer-readable storage medium or mediums encoded with instructions that cause an electronic device to perform a method for storing pixel data in a field corresponding to a pixel of an image, the field including an opacity bit and a set of bits, the method comprising the actions of:
- storing a color level value of a component color of the pixel in the set of bits, if the opacity bit is set to an opaque-indicating state;
- and
- storing a transparency level value in at least one bit of the set of bits and storing the respective color level value in other bits of the set of bits, if the opacity bit is set to a transparency-indicating state.
