COLOUR-Set colour table for image display

Usage:

colour table

Description:

This routine sets the colour table of the image display device. It can either be reset to a grey scale, or an RGB lookup table from a 3xN image can be used. The lookup table must have numbers between 0.0 and 1.0.

Parameters:

TABLE

The colour table file to be used. The programme will look for this file in the default directory and then in the standard Figaro directories. If TABLE is 'grey' or 'gray' this is trapped and a grey scale table is set up.

IDEV

The name of the imaging device, normally got from a global parameter which was set with the IDEV command.
