How to solve convert-im6.q16 issues
If you try to convert multiple jpg to a single pdf probably you will see this message: $ convert `ls -1v` file.pdf convert-im6.q16: Corrupt JPEG data: 94 extraneous bytes before marker 0xd9 `0.jpeg' @ warning/jpeg.c/JPEGWarningHandler/352. convert-im6.q16: not authorized `pictures.pdf' @ error/constitute.c/WriteImage/1056. To solve the first issue just convert the files to png and after to jpg again, like this example: mogrify -format png *.jpg rm *.jpg mogrify -format jpg *.png rm *.png To solve the second, just execute the following command: sudo sed -i 's/rights="none" pattern="PDF"/rights="read|write" pattern="PDF"/g' /etc/ImageMagick-6/policy.xml Enjoy it!
