tech2040 has asked for the wisdom of the Perl Monks concerning the following question:
Hello all,
I am currently a Perl novice. But a fast learner.
I need help.
I am trying to create a script that will read and display the file attributes(resolution, channels, bit depth, etc.) of jpeg files in a linux environment.
I need to know if there are any scripts or tutorials available that will show me how to accomplish this.
Any assistance will be greatly appreciated.
Thank you. |

Perhaps try Image::Info. It gives you what you want, plus plenty more. There's probably a module on CPAN to do most things you'll find yourself wanting to do. | [reply] |

Thank you,
But what about using itstat?
And how would I print the information (specifically the file resolution)to the Linux console?

Other alternatives/tools include Imager instead of ImageMagick and Image::ExifTool if you need to read EXIF information.

Not strictly a Perl solution but ImageMagick comes with a utility called identify which prints out image attributes in a nice parseable format. Or you could use the Perl interface to ImageMagick, PerlMagick, which others have mentioned.
