Writing PNG file in pure IDL with metadata [message #92144]

Hi All,

I have a bunch of Canon RAW .CR2 files that I'd like to transmogrify
into PNG files with nice informative metadata embedded in them.

Unfortunately IDL's inbuilt READ_PNG and WRITE_PNG don't know that PNG files can take metadata, and it looks like I'll be old, fat and bald before they do.
Wait, I am old, fat and bald... :-(

Anyway, I wondering if anyone has invented this particular wheel before.
I'd be happy to work with a pure IDL write routine, or some method of Spawning off a command to a 3rd party program.

TIA,

Andrew
