Re: [Gnuplot-info] loading an image

[Thomas S. <t.s...@fz...>]

there is no 'image.dem' in the 'demo' directory of version 4.0

'image.dem' is in the 'demo' directory starting from version 4.1/4.2

that means that features of version 4.2 may be not present in
version 4.0 and so 'image.dem' is not garanteed to work - and
obviously it doesn't work.
reason: the 'GPVAL_*' variables don't exist in version 4.0
