1. A method for mapping pixel data, the method comprising: comparing location information corresponding to the pixel data to a set of one or more special locations within an image frame, said special location being associated with a special mapping algorithm; comparing color coordinates for the pixel data to a set of one or more reserved colors, said reserved color being designated as not affected by mapping transformations; comparing color coordinates of the pixel data to a set of one or more special color regions, said special color region being associated with a color-specific mapping; and generating metadata based on tone or gamut parameters comprising the special locations, the reserved colors and the special color regions for the pixel data as adjusted by a color grader.
