Abstract
A first command is retrieved from a script containing one or more commands written for a first color space. The first command is associated with zero or more input buffers and zero or more output buffers. The first command has zero or more parameters. A behavior of the first command in the first color space and in a second color space is determined. The behavior comprises one of unique behavior, transparent behavior, and different behavior. The first command has the unique behavior when the first command only operates in the first color space. The first command has the transparent behavior when the first command generates similar results in the first color space and in the second color space. The first command has the different behavior when the first command generates different results in the first color space and in the second color space. Using the behavior of the first command, an operation associated with the first command is processed. The operation is processed in a preferred format based on current formats of the input buffers.
