I have a command as the follow :
convert mytest.pdf[3] -resize 20%x20% +contrast -sharpen 1 mytest.jpg
but it produces a pdf document with the created image embedded instead of a jpg !
I tried to do './configure -with-gslib' to solve the problem (after having already installed imagemagick) but it won't work (gs should be installed correctly) - what's the problem ? thanks
