Installing and using ImageMagick

Jun 23, 2015

*On my local Linux Mint (Ubuntu)

apt-get install imagemagick perlmagick

If package not found, then first do:
apt-get update
and then try the install again.

EXIF Data

http://stackoverflow.com/questions/1708417/how-can-i-extract-exif-data-using-perlmagick

http://hacktux.com/read/remove/exif

may want:
apt-get install libimage-exiftool-perl

exiftool coreopsis.jpg will provide some info about the image.

but this might be better:
apt-get install jhead

jhead coreopsis.jpg

if want to remove exif data from an image:

After ImageMagick is installed, you will have /usr/bin/mogrify available. The mogrify command can be used to strip Exif data from images.

mogrify -strip imagename.jpg

If you need to process a large number of files, use find and xargs:

find ./folder_of_images -name '*.jpg' | xargs mogrify -strip

install CPAN
reload CPAN
