Merge two UIImages
image, ios4, uiimage
Solution
That code looks correct (though I would recommend converting it to use a created CGBitmapContext for thread-safety), but is `imageB` supposed to be a JPEG? JPEGs don't support transparency, so, in order for the blending to work, it should really be a PNG.
Problem
I have imageA (taken from the users iPhone camera) and imageB, an image with a silly boarder (for eg) with plenty of transparent alpha space. What I would like to to do is to merge these two images, laying imageB over imageA, and then saving them as imageC for other work. Is there a way to do this? Cheers I've got this so far ``` -(void)merge { CGSize size = CGSizeMake(320, 480); UIGraphicsBeginImageContext(size); CGPoint thumbPoint = CGPointMake(0,0); UIImage *imageA = imageView.image; [imageA drawAtPoint:thumbPoint]; UIImage* starred = [UIImage imageNamed:@"imageB.png"]; CGPoint starredPoint = CGPointMake(0, 0); [starred drawAtPoint:starredPoint]; UIImage *imageC = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); imageView.image = imageC; } ``` I can't see/dont know what I'm doing wrong here
