Abstract
A method for converting color data includes reading from a memory the color data represented in a first color space; converting the color data into un-premultiplied color data; converting the un-premultiplied color data from the first color space to a second color space; converting the un-premultiplied color data in the second color space into first premultiplied color data; and writing the first premultiplied color data to the memory.

A method for processing pixels, comprising:
- reading from a memory color data of the pixels represented in a first color space supported by a first device;
- converting the color data into un-premultiplied color data;
- converting the un-premultiplied color data from the first color space to a second color space supported by a second device;
- converting the un-premultiplied color data in the second color space into first premultiplied color data;
- and
- setting the pixels to the first premultiplied color data.

A color conversion system for processing pixels, comprising:
- a memory that stores color data of the pixels represented in a first color space supported by a first device;
- and
- a processor that:
- reads from the memory the color data,
- converts the color data into un-premultiplied color data,
- converts the un-premultiplied color data from the first color space to a second color space supported by a second device,
- converts the un-premultiplied color data in the second color space into first premultiplied color data, and
- sets the pixels to writes the first premultiplied color data.
