I'm trying to find a way to quickly read image headers (specifically jpgs at
the moment) with out loading the whole image as an System.Imaging.Image.
Anybody point me in the right direction or am I going to need to write a
header parser from scratch?

I'm also interested in this, and additionally whether one can read out the
contents of TIFF file IFDs without reading in image data.

Hi Steve,

I ended up having to do this myself, I haven't really tidied the stuff up
much, but this might help you.

Hi,

Thanks, I'll have a look at it. I think we're considering moving away from
using the GDI+ stuff at all because of its limitations (CMYK, greyscale,
16-bit support etc.). I'm not generally that impressed by its lack of
support for handling image files; hopefully they plan to address it in the
future.

Thanks again,

Steve
