copied!<p>@YAR your solution is working properly.</p> <p>There is only one thing which does not fit my requirements: The whole image is resized. I wrote a Method which did it like the <code>photos app on iphone</code>. This calculates the "longer side" and cuts off the "overlay" resulting in getting much better results concerning the quality of the image.</p> <pre><code>- (UIImage *)resizeImageProportionallyIntoNewSize:(CGSize)newSize; { CGFloat scaleWidth = 1.0f; CGFloat scaleHeight = 1.0f; if (CGSizeEqualToSize(self.size, newSize) == NO) { //calculate "the longer side" if(self.size.width > self.size.height) { scaleWidth = self.size.width / self.size.height; } else { scaleHeight = self.size.height / self.size.width; } } //prepare source and target image UIImage *sourceImage = self; UIImage *newImage = nil; // Now we create a context in newSize and draw the image out of the bounds of the context to get // A proportionally scaled image by cutting of the image overlay UIGraphicsBeginImageContext(newSize); //Center image point so that on each egde is a little cutoff CGRect thumbnailRect = CGRectZero; thumbnailRect.size.width = newSize.width * scaleWidth; thumbnailRect.size.height = newSize.height * scaleHeight; thumbnailRect.origin.x = (int) (newSize.width - thumbnailRect.size.width) * 0.5; thumbnailRect.origin.y = (int) (newSize.height - thumbnailRect.size.height) * 0.5; [sourceImage drawInRect:thumbnailRect]; newImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); if(newImage == nil) NSLog(@"could not scale image"); return newImage ; } </code></pre>
