I've used Veusz to create some nice 2d-density plots using the "image"

However, when I export my graph to PDF the colours change considerably.
I'm using the bluegreen colormap (inverted).
Has anybody else experienced similar problems?
I don't see the problem with the mandelbrot example with bluegreen on
linux, after exporting to PDF. There is some smoothing introduced, but
the colours look ok.
What version and platform are you using?
Thanks

I'm using Fedora 22 with the Veusz package that comes with it (1.23)
I've just tried the mandelbrot example and that looks fine! The issue
only shows up when I use really big "pixels", for example when creating
a "heat map" or some other small matrix plot.
I can recreate the issue in the mandelbrot exaple by using a text editor
to replace the image data with something like this:
0 3 3 4 4 4 3 3 4 4 5 5 5 10
0 4 4 4 4 4 4 5 6 6 6 5 5 10
0 4 20 5 5 5 5 6 8 7 6 5 5 12
0 20 20 20 5 5 6 6 8 8 6 7 7 20
0 4 20 5 5 5 6 7 9 12 7 8 13 15
0 5 4 7 6 7 8 11 14 20 9 10 16 18
0 5 4 7 6 7 8 11 14 20 9 10 16 18
0 4 4 5 5 17 6 7 9 12 7 8 13 15
0 4 4 5 17 17 17 6 8 8 6 7 7 20
0 4 4 20 17 17 5 6 8 7 6 5 5 12
0 4 20 20 20 4 4 5 6 6 6 5 5 10
0 3 3 20 4 4 3 3 4 4 5 5 5 10
0 3 3 3 3 3 3 3 3 3 4 5 5 9
0 3 3 3 3 3 3 3 3 3 3 5 5 9
Maybe I'm abusing the image widget for this? I've also noticed if you
open the pdf you get with an example like this one in inkscape, it
doesn't create a matrix of vector squares, but a (blurry) image.
Thanks,
Michael
