Ok I guess should explain,
After much searching the only thing I could find to do what I want if FOP.
I want to be able to read in either a gif or a jpeg and check the dimensions
of it.
AWT has to much overhead because it attempts to renderthe image. Whereas FOP
seems just to reader the header information.
As I can't guarantee that my application will run using JDK 1.4 I can't rely
on JavaImage io classes.
attached is a jpeg that wont read,
I then went ahead and converted a working gif into a jpeg using Photoshop.
It doesn't work either.
If anyone has another suggestion to do what I want to do, they're mor than
welcome.
I know it's only using a small part of fop, and not using it for what fop
was designed for, but it does work, If I can get it to read a jpeg.
Regards
Steve

Subject: Re: Can't read JPEG file using JPEGReader
Can you please start by telling us what you're trying to do? Have you
tried a different JPEG image? There are JPEG's that won't work. Maybe
you just got something that's not supported. Can you post a little (!) JPEG
that doesn't work? Anyway, I'm wondering why you're working with
ImageReaderFactory and friends at all.
