Quartz Composer in iOS

Question

I am new to iOS platform. Is there anyway I can use quartz composer library embedded into my iPhone app? e.g I would like to get RGBA from a particular pixel from an image (UIImage) using IMAGE PIXEL. get-color-image-pixel

OR can i use existing framework in xcode4 to achieve above scenario??? thanks

Have a see Quartz Composer for iOS. That runtime implementation for iOS. This project makes it possible to load, display and interact with .qtz files on iOS.

Good luck

No, the Quartz Composer framework does not exist on iOS.

To extract pixel color data from a UIImage, see this question: How to get pixel data from a UIImage (Cocoa Touch) or CGImage (Core Graphics)?
