Hi, octave:12> which pcolor pcolor is the user-defined function from the file /Users/daniel/octave/plot-1.0.0/pcolor.moctave forge function. But imagesc does something very similar, if you want base octave stuff.
I _do_ want vector graphics, these patches are lowres, i.e. 5x5, and in inkscape I shear them around to emulate 3d stacks, and that would look rather bad using pixel graphics.

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.Søren Daniel Oberhoff skrev:Hi all,I am running a self compiled octave 2.9.12 together with an equally self compiled gnuplot 4.3. I make a plot of a small gaussian image patch like this:[x,y]=meshgrid(-2:2,-2:2); g=exp(-(x.*x+y.*y)/8); pcolor(g); and then print it like this: print -dpdf gausmask_octave.pdfcuriously the print receives some interpolation, fuzzing up the originally blocky image, which is not what I want, because this is for a paper and I want to show what I actually use. Is there a way to switch this smoothing off? btw, is it a known bug in octave 2.9.12/gnuplot 4.3 that the hold setting is always on, i.e. I always have to clf before a new plot and hold on/off has no measurable effect?anyhow, love the image capability brought out in gnuplot now.
