What am I going to need to set meta data
Hey folks. My endless quest to complete a program I have been writing for ages has at the moment brought me to this problem...
I am using lucene to search through a pile of text documents. Its great. Problem is I also have piles of images... :-( these are not text and so cannot be searched.
One good thing does come from this however- the user creates the images in the program.
I was wondering if there was a way to add a string of text into PNG files as the user saves them, so that later on, when lucene is searching to index files, it can grab the text string out of the png and index it?
So just to re-phrase my main question:
Can I set/get metadata?
If yes, what libraries/methods do I need and are there tutorials around (I havent found any yet)?
Thanks in advance.
Jason.
