Legacy ImageMagick Discussions Archive

Hi everyone. I'm newbie a bit in imagemagick.

I wanna convert some pdf magazines to jpg files. but when my pdf has many images in its pages, this error appears, and jpg files generates in bad way :

**** Warning: File has insufficient data for an image.
error: cannot decode code stream
unable to decode JPX image data.

Please help

What version of IM and what platform. What was your command line?

JPX means that the image is in JPEG2000 format. On unix you need the Jasper delegate library.

Does convert -version tell you you have JP2 or JP2000?
