Hello to all,
I am new to iPhone Development and even new to Image Processing but guyz i all of your help I am learning Image Processing in Bits and Pieces What i have learned so far is that how can i obtain the Actual pixel data from CGImage object and how to create a new modified image here is the code :

Code:

 CGImageRef sourceImage = theImage.image.CGImage;
    CFDataRef theData;
    theData = CGDataProviderCopyData(CGImageGetDataProvider(sourceImage));
    
    UInt8 *pixelData = (UInt8 *) CFDataGetBytePtr(theData);
    
    int dataLength = CFDataGetLength(theData);

But right now i am struck at a point how can i increase/Decrease the sharpness of UIIMageView With a Slider.
Please share your thoughts with us so it will benefit all of us in someway.........
Regards,
