Sun 23 Dec 2018 09:46:44 PM UTC, comment #1: ConvertType has a new option called `--colormap' with the ability to specify a color map to display single-valued datasets (for example FITS images) in formats that support color (for example PDF or JPEG).

Currently only RGB and CMYK are supported. Add Hue-Saturation-Lightness and Hue-Saturation-Value color spaces too for more generality. |

An `--rgbtohsv' option was recently added to convert the input RGB channels (for example from a JPEG image) to HSV (for saving as FITS).
But we also need its inverse. Maybe an option like: `--inputmodel'. Where the user can specify the nature of the input color model when there is more than one color channel (for example RGB, HSV, CMYK).
With this option, if the three input channels are specified as HSV, then if the output is a format that only supports RGB (for example JPEG, EPS, or PDF), we can convert the HSV color channels to RGB.
