Re: print question

[Søren Hauberg]

Hi,
  First of all, what is "pcolor"? I assume it's a function you've 
written that displays an image...
  Anyway, I don't quite understand your problem. Is the image 
interpolated when shown on screen or when you look at the saved image 
with a pdf viewer? On my system gnuplot doesn't do any interpolation 
when displaying images. If it is the pdf that's interpolated then I 
guess it's due to your PDF viewer. Why not save the image to disc as a 
PNG (or similar) file? Vector graphics (like PDF) is just awful for images.
