TV and PostScript [message #7866]

Hi everyone,

I would like to print a colour map with TV on a PostScript
device.

I have a grid with my data, let's suppose it is a 10 x 20 floating
array named mygrid.

I want to use all available display space, so I do

biggrid = congrid( mygrid, !d.x_size , !d.y_size )
tv, biggrid

On a window, this causes no problems.

But, if I select a postscript device , !d.x_size and !d.y_size are
very very big (there are 1000 pixel for cm, so there are about 20000
pixels for dimension). This makes for a 20k x 20k grid, about 400
million elements. Obviously, this breaks IDL.

I do not want 1000 pixel per cm! But I cannot change the resolution
(or, I am not able to change it). What can I do?

Has anybody made a colour map with PostScript???

Is there any way out of this problem???

Help is quite appreciated...

Thanks in advance.

Andrea
