Yes, Win32::OLE::Const exports a bunch of constant subroutines that look something like this: phKeyPNGInterlaceType. I was trying to get a list of possible ones because the only example of this I can find (in this node) only uses PNG format and doesn't deal with compression. It looks like your code worked though, so I'm off to dig through 600 lines of output. Thanks!
