Hi, I want to develop an application in which i want to be initialize the matrix for manipulation. The code as follows, struct pixel { Byte r, g, b,a; int count; };

• (NSInteger) processImage1: (UIImage*) image {

  struct pixel* pixels = (struct pixel*) calloc(1, image.size.width * image.size.height * sizeof(struct pixel)); if (pixels != nil) { // Create a new bitmap CGContextRef context = CGBitmapContextCreate( (void*) pixels, image.size.width, image.size.height, 8, image.size.width * 4, CGImageGetColorSpace(image.CGImage), kCGImageAlphaPremultipliedLast );

  if (context != NULL)
  {
      // Draw the image in the bitmap
      CGContextDrawImage(context, CGRectMake(0.0f, 0.0f, image.size.width, image.size.height), image.CGImage);
      NSUInteger numberOfPixels = image.size.width * image.size.height;
  
  
  while (numberOfPixels > 0) {
  
  
  if (pixels->r == 254 || pixels->g == 77 || pixels->b==254)                           {
              numberOfRedPixels++;
          }
  
  
      pixels++;
      numberOfPixels--;
  }
  
  
  CGContextRelease(context);
  
  
  }
  
  
  free(pixels);
  

  }

  return 1; }

I want to implement the matrix inside the function of - (NSInteger) processImage1: (UIImage*) image {} The matrix should have be row = image.size.width and column = image.size.height.
