mg_decomposed.pro

mg_decomposed, dec [, old_decomposed=long]

Set the decomposed mode, if available in the current graphics device i.e. equivalent to:

  device, get_decomposed=oldDec
  device, decomposed=dec

The main advantage of this routine is that it can be used with any graphics device; it will be ignored in devices which don't support it.

This routine uses IDL 7.1 functionality for the PS device, but fails gracefully if the IDL version is less than 7.1.

dec in required type=long

decomposed mode: 0 for indexed color, 1 for decomposed color

old_decomposed out optional type=long: decomposed mode before mode is changed (only available in X and WIN graphics devices)

Requires:

IDL 7.1
