Interfaces: PC and MAC and the screenGamma property...

[Chipp Walters]

Hi all,

I ended up getting an iBook over the holidays to do some cross-platform
development. Been awhile since I've used Macs for any length of time (they
sure have changed;-0)

Anyway, I spent a few hours today trying to track down a color issue and
here's what I found out:

If you are like me, you may use animated GIF's to create blinking lights,
progress bars, etc.. And if you use ImageReady and Photoshop, you can create
them easily so that the GIF overlays what's beneath it seamlessly. Your user
will never 'see' the boundaries. But...there's a catch for cross-platform
developers. Different images have native gamma correction built in, and this
can create problems when combining GIFs, PNGs and JPGs.

I've created a stack to demonstrate the issue, and offer some solutions on
how to best solve it. Just type into your msg box and hit return:

Please let me know (you Mac folk) if you know of other workarounds!

best,

Chipp
