[squeak-dev] Historical help needed: PNGReadWriter
class test1


Hi Karl,

Thanks for the help. I looked for the citrus-* files
too but I stopped there.
The PNGSuite was the key. I've now got more info than
I wish to process.

So given PNGSuite test files are available, do you
know of anybody out there we can recruit to write a
squeak version of PNG tests?
