Dear all, here I'm with a question maybe stupid but I did not found an
answer neither on David Fanning website. I'm trying to create a
postscript file from an image using imdisp routine from Liam.Gumley
and the beautiful color table fsc_brewer from David. Actually I use
this setup for opening the file
set_plot,'ps'
device,filename=fname,/portrait,/encapsulated,$
ysize=12,xsize=14,/isolatin1,font_size=15,/color, bits_per_pixel = 8
loadct, 24, file = $
'/ricercatori/fb/nicolalib/colortables/fsc_brewer.tbl'
I would like to have the axis of the image in black and then using the
brewer color table (number 24 on the tbl file created by David). So I
put as follow
imdisp,image,/interp,/axis,col=fsc_color('black')
the problem is that it introduces some black spots into the image
which are not visible if I did not manage to change the axis color. I
suppose that this is due to the fact that I modify the color tables
introducing the black color but I did not find a way to overcome the
problem. The same results I obtain if I add to the image the colorbar
(using David latest routine). the only way I have is to let all the
axis to be red (or better the lowest color of the colortable). Any
suggestion on a way to overcome the problem?
I hope I' ve been clear and I apologize if the answer is stupid or
already treated but I did not find it
Nicola
