craigmbooth / nloadct.pro

Created February 5, 2013 18:29

This is my replacement for IDL's loadct command. It is pretty much interchangable with the default version but the number of colour tables runs over 100. Also allows easy creation of new colour tables by automatic interpolation from a series of rgb values.
