Is it possible to use true colour with ION script? My program make an
RGB output which ION handles like this...

IDL> set_plot, 'Z'
IDL> device, SET_RESOLUTION=[320,256]

...code...

IDL> ion__img = tvrd()
IDL> tvlct, ion__r, ion__g, ion__b, /GET
IDL> ion__tmp = bytarr(3, 320, 256)
IDL> ion__tmp[0, *, *] = ion__r[ion__img]
IDL> ion__tmp[1, *, *] = ion__g[ion__img]
IDL> ion__tmp[2, *, *] = ion__b[ion__img]
IDL> ion__img = ion__tmp
IDL> !QUIET = 1
IDL> write_jpeg, 'C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\ion1452.jpg',
ion__img, TRUE=1

which is assuming that I'm using a colour table. Comes out b/w. You can
choose between png8, png24 and jpeg24, but they all do the same. Don't
seem to be any true options for the ION_IMAGE tag.

regards,
Greg
