ImageMagick and ghostscript

[Tommaso Twain]

I have a command as the follow :

convert mytest.pdf[3] -resize 20%x20% +contrast -sharpen 1 img.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, but won't work !? what's the problem ? thanks

ps

It seems strange but installing ImageMagick (on CentOs 4) i have "no" value about jpeg1 support so i've manually installed libjpeg, but it does not work yet

You should have gotten a JPEG. I can't see why you didn't.

NOTE that [3] should be in quotes or the shell may interpret it, and not ImageMagick.
