Help on reading in EXIF data in Java

Hi,

I'm currently working on a java program which imports in EXIF data from a photo (jpeg in format). Am I able to read in composition of the photo? (I.e. if I have 3 pictures, 2 of white backgrounds and 1 black background) Will be there any ways I can differentiate them through the reading in of EXIF data? Please advise.

Thanks.

I'm not sure what you are asking....if that data is in the metadata of the image then yes. Of course this depends upon the source of the image, I'd think that typically a jpeg would lack any sort of information in the meta data that defines the background of the image.

Hi doWhile,

What I'm essentially asking if there's any ways to tell between 2 photos (say 1 black and 1 white), is there a meta data tag that I can read into java to differentiate between the 2 photos.

Thanks. :)

As I said, generally speaking - no. You will probably have to inspect the image pixels themselves
