you could look at http://www.cgsd.com/papers/gamma.web.html
great article. thanks.
it mentions that the PNG format may support gamma correction
internally.
anyone know how i could use that to use only one pic file for all
platforms?
My PNG Utilities plugin can read/write embedded gamma (available here:
<http://developer.chaoticbox.com>) but I would highly recommend leaving
such settings up to the user. Gamma "correction" is rarely correct
system to system or eyeball to eyeball for that matter. You can start
with some generally accepted values but the user should have the final
say as to what is correct for his system and/or eyeballs.
Also note that gamma correction != colour correction, so the colour can
(and will) be way off even if you ramp the gamma perfectly. I'd simply
suggest not worrying about this stuff unless it's essential to your app
- your users probably won't care or notice. If it is essential, provide
some sort of visual calibration preference.
Frank.
