Pavel I will look into this in the weekend. At some point I will want to overhaul the configure.py script. The purpose is, among others, to simplify the code required to do this kind of tests. The test above is relatively easy to do. Something that I should, probably, take into account is the order of the tests. In the sense that if we different \convert lines we probably retain the last... -- José Abílio -- lyx-devel mailing list lyx-devel@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-devel

Jose, could I ask for pythonic help? We would need a routine in configure.py which check whether to remove eps->png conversion in case IM bans those conversions. That could be done this way by checking return status of the conversion. In bash that would be something like this: echo '%!PS' > /tmp/.lyx_configure_test.eps convert /tmp/.lyx_configure_test.eps /tmp/.lyx_configure_test.png if ! [ $? == 0 ] ; then # remove eps->png conversion from configure settings, i.e. set \converter "eps" "png" "" "" fi Completely different way would be mimicking what IM internally does with GS when converting eps->png. I already checked little bit and unfortunately it won't be oneliner if we want to get resolution right. But probably doable with additional script of our own.

On my debian adding this to preferences sort of fixes the issue: \converter "pdf6" "png" "pdftoppm -png -singlefile $$i > $$o" "" \converter "eps" "png" "" "" Problems I see: - the zoom factors in lyx window are not consistent with previous IM conversion (you need to remove cache to test this) - not sure how is the pdftoppm conversion portable to windows/mac environment We could perhaps check policy.xml of IM and add those only in case eps/pdf is banned when doing reconfigure.
