iPhone Image process

Question

I have taken the image from UIImagePickerController, but the file looks too big to be transfered through internet, I'd like to resize the images. I couldn't find any method related to the image process. Any recommendation?

Thanks.

Answer 1

You could create a context of the desired size using UIGraphicsBeginImageContext(), then draw the image to the context using UIImage's -drawInRect: method, and finally use UIGraphicsGetImageFromCurrentImageContext() to pull a new UIImage back out.

Cool, thanks!
