    Default Retrieving Meta-Data from a File

    Hello everyone, id like to know how to retrieve the meta-data a file contains. Ive managed to retrieve some, like Name of File, Size, Path, isHidden, Icon, etc.

    But i still need more data, and can't find the methods to retrieve them. Im working with .TIF files. This is everything i need:

    Title [CHECK]
    Author
    Description
    Resolution X
    Resolution Y
    Dimensions
    Size [CHECK]
    Date/Time of Creation
    Date/Time of last modification
    Monocromatic / Color
    Bits in the Color Pallete

    Well the TIFF spec tells you where the information is stored in the file itself, I thought you were trying to implement your own TIFF reader so to speak. Are you just after some java library that will do it for you?

    I thought there was a library that would do the job, not just for TIFF files but files in general, i suppose there isnt one.

    How about you grab a hold of this jar file.

    /com/drewnoakes/metadata-extractor/2.4.0-beta-1/ - Maven Repository Browser - Jarvana

    You need metadata-extractor-2.4.0-beta-1.jar and in it there will be a class called something like TiffMetadataReader

    Enjoy!

    You put it in your lib folder of your application or where ever you store your external jars. Just make sure its on the classpath when you run your own application.
