  • Thread-topic: Image scaling

I have code that creates a JPEG thumbnail in an NSData using
NSBitmapImageRep and drawing into a new context, in a very threaded context
(often several threads doing it at the same time on different directories).
It was, admittedly, leaking like heck down in the OS somewhere, but I
wrapped it in my own autorelease pool and that seems to have cured it.  I
have had a thread work on 1M+ images and not run out of memory.

Not sure how to help you with the metadata, I explicitly wanted to strip it
for my app, so I can't help you there.  But let me know (off list) if you
want to see my code, and I'll happily provide it.  I'm not 1000% sure it's
rock solid, but I've been using it for a few months now in testing, and I
can't break it...
