Creating UIImage from raw RGBA data

Question

I have been trying to convert an array RGBA data (int bytes) into a UIImage. My code looks like as follows:

/*height and width are integers denoting the dime         


        

Answer 1

I just independently verified this problem, I think it should be reported as a bug to Apple. +(UIImage)imageWithCGImage: doesn't properly transfer the width and height of the source CGImageRef to the UIImage.

Answer 2

The problem is solved now. I get the image that I want displayed but still unable to figure out why the width and height are different. Essentially nothing wrong with the program per say. The only problem being width and height.

Answer 3

It turns out the problem is a pretty silly mistake that both of us overlooked. UIImage dimensions are stored as floats, not integers. :D

Try

NSLog(@"resultImg width:%f, height:%f",
          newImage.size.width,newImage.size.height);

Instead. The image size has been transferred correctly.
