reading EXIF data from a jpeg file
Feb 10th, 2010, 3:07am  
Hi,
Has anyone used Processing to read the EXIF data from a jpeg file?
At the moment i only want the resolution information, but other things like the ratings and Camera model would eventually come in very useful as well!
Thanks

Pete

You should try and use the search facility of this forum... Smiley Or of Google or similar.

Found, for example: Java and Jpeg Metadata which mentions, among others, Sanselan (Apache Image library) and the good old Java Advanced Imaging (JAI) tool, which extends the standard ImageIO class.

Note also that the good old ImageInfo.java file by Marco Schmidt can provide lot of information on images (like resolution) with a  lightweight class.

Hi,
Thanks for the info,
I was looking for "jpg exif data" which didn't bring up much!
You've come at a different angle which is much appricated!
Silly question, inside the website you referenced it suggests using the "Java Advanced Imaging Image I/O Tools" is that already in the processing build or do i need to go and download it?
Sorry a bit of a novice when it comes to the setup of these things!

Thanks

Pete

No problem, the art of proper googling is delicate... Smiley
I just searched exif java actually!

Java Advanced Imaging API is a free download from Sun. You have to add it to classpath (eg. in a code folder in your sketch folder, or as a library) to use it.
