Hooray!! I did get this code to work but I guessed my way through it. Still don’t understand it but maybe I will. Thanks so much for the code!!

This code is way over my head.
I Really Really need to figure out how to use it.
In my app I am attaching a saved image to an email body so I don’t have a UIImage to manipulate. I only specify a path to the image in the documents directory, pull it into NSData and attach it as a mime type.jpg. It works great but there again the image is turned left 90deg when the recipient views the email. Does anyone have a snippet of code that will help me understand how to get the saves image into UIImage so I can expose it to this function?
Thanks for the code though. Once I grasp this my app is gonna rock big time!

Thanks for sharing this code, i works on iOS4 but not on iOS3.1 : i have a “EXC_BAD_ACCESS” for the line :
“CGContextDrawImage(UIGraphicsGetCurrentContext(), CGRectMake(0, 0, width, height), imgRef);”

How can i fix it ? Please

Thanks for this!

One small thing to add. A small bug in this code, when you’re calculating the bounds near the top of this method, you’ll need to take the floor of the result after calculating in the ratio. If you do not do this, it’ll be rounded up to the next integer and leave a white strip on the right or bottom edge. So, just change it to this to fix it:

if (ratio > 1) {
bounds.size.width = kMaxResolution;
bounds.size.height = floor(bounds.size.width / ratio);
}
else {
bounds.size.height = kMaxResolution;
bounds.size.width = floor(bounds.size.height * ratio);
}
