Attached foo.svg, result of

from comment #1, run with MXE-Octave, compiled with gl2ps ver. 1.3.9.
(with ver 1.3.8 it was empty figure file...)

(file #35232)

gl2ps has been patched and the current development version produces properly scaled images. AFAIU there will be a a release of gl2ps soon [1].

I think we can close this report as it has been fixed upstream

I've done some more testing and I'm pretty certain this is a problem with gl2ps rather than Octave. Until they do something about this images just aren't going to output well to svg.

Alas, I'm not certain this isn't an Octave bug with the printing of 'image' data to svg. I used rectangle() to create 4 differently-colored boxes on an ordinary plot background. When I print this the svg is correct. I'm attaching that file as svg_rect_tst.m

Secondly, the white polygons are present at the beginning of every svg file. They represent the axis background. You can verify this with

Now I get the following in the svg file.

I looked at the content of the svg-file, and found that the four rectangles are being drawn as white.

This appears to be a bug or missing feature in gl2ps. The files where the bug is likely to be found are libinterp/interp-core/gl2ps.c and/or libinterp/interp-core/gl2ps.h. When I have time, I hope to take a look. In the event someeone gets to this before me, the bug is found the change should be made upstream at the link below.
