Hello to all, I´m definetly not the most knowledgable person about this in this list, because I´m not a developer !! But I share the knowledge I have with the people of this list. So far as I know, shares iOS, the operating system for iPhone, iPod and iPad some core technologies with Mac OS X. This includes parts of Core Graphics and the Quartz 2D Imaging model including dealing with ICC-profiles for Gray, RGB and CMYK and rendering Intents. http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Refere... <http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Reference/CGColorSpace/Reference/reference.html%23//apple_ref/doc/uid/TP30000949> For detailed technical discussions, Apple offers following mailinglists for developers: http://lists.apple.com/mailman/listinfo/quartz-dev (about programming and quartz in general) http://lists.apple.com/mailman/listinfo/colorsync-dev (about programming and colorsync) What I have not found through a simple web research, is any information, how the display colors are characterized/ profiled in iOS4. I still don´t know: - does iOS 4 provides a color characterization / profile for the display ? - If yes, is this an ICC-profile or an internal format because of speed optimization ? - if yes, is there any documentation about it ? - if yes, is this hardcoded, or can a developer change the display color characterization / profile ? If any one would ask this questions in one of the mentioned mailinglists. Best regards Jan-Peter Am 30.07.11 11:00, schrieb edmund ronald:
Jan-Peter,
Maybe you can educate us further, as you seem to be the most knowledgable person here ?

Hello, iOS4 supports ICC based colormanagement, see also here: http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Refere... <http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Reference/CGColorSpace/Reference/reference.html%23//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.

I think there is already a profile etc in there somewhere. It shouldn't be hard to color manage a jailbroken device, the problem is that the color management interface is not available *yet* on locked-down devices.

Does not seem like a "system" solution?
iPad. Another example of color management as an after thought...
