Hi,

I'm currently using boost serialization in order to save/load my data 
structure. The problem is that it contains some images and even with the 
ZIP compression the files are really big (4x bigger than the jpeg).

So, I'm looking for a way to compress a RGB/A image (HDR or not) 
(without file operation) in memory. If possible without using any image 
compression library, we already use OpenImageIO but it is not possible 
for now !

Any idea ?

I have found the GIL library, but can't find how to:

1) convert raw to GIL image
2) serialize the GIL image

1) deserialize the GIL image
2) convert the GIL to raw image

Of course, the goal is to have a good compression without writing 
temporary file !

Thanks
