Why is the imagedata value different from Win32 to MacOS platforms?

[Chipp Walters]

Malte,

Are you saying when using this plugin, there is no difference between
PNG files (gamma-wise) between platforms? If that's true, then you are
wonderful!!!

(Even if it's not true, you're still wonderful ;-)

Could you possibly post a stack which would demonstrate this? Here's
what I would suggest:

Capture a rect from a blank card (with a custom card bgcolor) and then
paste it into Pshop, then make half of it 50% transparent, export as
SuperPNG and import back into the stack. The half that's not 50% trans
should match exactly the bgcolor of the card on both platforms.

best,
Chipp
