I found out that IM uses by default DPI of 72 when calling GS so this problem is solved by using "pdftoppm -r 72 -png -singlefile $$i > $$o" Transparency is lost but I don't think that is a big deal. > - not sure how is the pdftoppm conversion portable to windows/mac environment Actually we have GS under our control for Win, not sure about Mac but mayb the IM policy is not to ban eps/pdf conversions. > We could perhaps check policy.xml of IM and add those only in case eps/pdf is > banned when doing reconfigure. 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.
