TRC (tone reproduction) applies color adjustments that you made in Show to an image, so that you can apply the same adjustments in a job.
The input must be an 8-bit, 3-band color image. The output is an 8-bit color image with the adjustments applied.
The command has 5 elements separated by #. The first is three hex characters that together say which of 12 colors to change. The other four are integers: the changes in brightness, contrast, saturation and hue angle. For example, FFF#0#0#0#0 means all 12 colors, with no changes.
