Hi Phil, good to hear from you.

Yeah, I separated them for the time being. I don't think it's big deal
to add a bunch of test images to the boost source tree. It isn't
really that big after all.

When running the test suite I write out a lot of pictures which
amounts to 5MB. But this is only done once since the files are being
overridden at the next run.

If there is resistance to add 20MB in test images I would have to
resort to images in memory ( std::stringstream ). I cannot recommend
such approach.

The biggest problem I can see is the configuration of the test suite.
There are some manual steps involved, as they are described in the
readme.txt. I need to talk to the boost build guys to get the
configuration done automatically. But that's for after the review.

Every time you read/write a jpeg or a png you use the setjmp/longjmp
combination. I have tested it on my own machine and it works pretty
well. There are no tests that are targeted specifically at

Does that answer your question?
