Hello all, Looking futher in the programmers guide for Quartz at: http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Concep... I found following statement: ********* Introduction Quartz 2D is an advanced, two-dimensional drawing engine available for iOS application development and to all Mac OS X application environments outside of the kernel. Quartz 2D provides low-level, lightweight 2D rendering with unmatched output fidelity regardless of display or printing device. Quartz 2D is resolution- and device-independent; you don't need to think about the final destination when you use the Quartz 2D application programming interface (API) for drawing. The Quartz 2D API is easy to use and provides access to powerful features such as transparency layers, path-based drawing, offscreen rendering, advanced color management, *********** This text from Apple states clearly, that iOS provides "advanced color management" !! So please ask Apple and not me, if the Apple statement is correct or not. I´m not a developer. Jan-Peter Am 30.07.11 15:41, schrieb Roger Breton:
This is where I got my information from :
==================
Color Management for iPad... iOS 4.x does not have built-in color management support. BUT, there are some strange color conversions when you synchronize picture (with iTune) to your iPad.
I did many tests in order to find a way to get better color accuracy for color pictures on the iPad screen.
No!, the default color space to use for color pictures is NOT sRGB!
Here is (link) a resumé of what I found (the problems) and soon, the solution!

Let me know what you think about it !

Hello, iOS4 supports ICC based colormanagement, see also here: http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Refere nce/CGColorSpace/Reference/reference.html#//apple_ref/doc/uid/TP30000949
it took me 2 minutes to find this document through Google. May be we should do a little bit more research, before we are doing statements about iPad and color management in this list.
