Hi, i tryed to read the exif metadata from some jpegs for a new programm i'm working on, but i don't get it it to work...

I searched this and the old forum and found this:

http://processing.org/discourse/yabb2/YaBB.pl?num=1223457059

"Rogue-a-muffin" use the exif library from drewnoakes.com for his work, i copied the code and give it a try (Processing1.5.1), and it gives me an error that i dont understand. (Cannot reduce the visibility of the inherited method from FilenameFilter).... can you help me out here?

Thank you!
