Package: libgl2ps1.4
Version: 1.4.0+dfsg1-2
Severity: important
Dear Maintainer,
* What led up to the situation?
GNU Octave can't export figures containing image objects to SVG format.
* What exactly did you do (or not do) that was effective (or ineffective)?
The following Octave code fails:
image ()
print toto.svg
* What was the outcome of this action?
The image is absent from the resulting figure. Warning message:
GL2PS warning: GL2PS must be compiled with PNG support in order to embed
images
in SVG streams
* What outcome did you expect instead?
This should work, and it does if I compile GL2PS with PNG support (I only
have
to install libpng-dev for that to happen automatically) and LD_PRELOAD this
library before running Octave.
Thanks for your work.
