Color conversion

This class provides functionality to convert between different color spaces, e.g. sRGB and HCL.

To use any functionality in this module, pass a list with 3 floating point values in a function, e.g.:

color_in_sRGB = [1.0, 0.0, 0.0] # red color in sRGB color space
color_in_HCL = sam.DataModel.Type.ColorCoversion.toHCL(color_in_sRGB)

Note that the conversion is not exact. For example, a converstion from sRGB to HCL and then back from HCL to sRGB will result in values that will slightly differ from the original ones by some numerical error due to approximations in conversion functions.
