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

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)?

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
