关于将叠加层图像与捕获图像iOS合并的问题 [英] Issue on merging the overlay image with capture image ios

问题描述

我正在开发相机应用程序，其中我捕获了一张叠加图像.我正在使用以下代码进行组合图像的处理，但是徽标的位置不合适.

I am developing the camera app in which I put the one overlay image, As I captured the Image. I am doing the processing to combine the Image using the Following code but the position of the logo is not proper.

- (UIImage*)addOverlayToBaseImage:(UIImage*)baseImage {
     UIImage *newImage = [self CombineImage:baseImage];
     return newImage;
}

-(UIImage *)CombineImage :(UIImage*)myCapturedImage{ 

  CGSize finalSize = [myCapturedImage size];
  CGSize overlaySize = [overlayGraphic size];
  UIGraphicsBeginImageContext(finalSize);

  [myCapturedImage drawInRect:CGRectMake(0,0,finalSize.width,finalSize.height)];

  CGFloat xScaleFactor = finalSize.width / 320;
  CGFloat yScaleFactor = finalSize.height / 480;

  [overlayGraphic drawInRect:CGRectMake(30 * xScaleFactor, 100 * yScaleFactor, overlaySize.width * xScaleFactor, overlaySize.height * yScaleFactor)]; 

  UIImage *combinedImage = UIGraphicsGetImageFromCurrentImageContext();

  UIGraphicsEndImageContext();
  return combinedImage;
 }    

我从此网址获得引用[ http://www.musicalgeometry.com/?p = 1681] 并使用捕获相机视图和图像中的全部内容

I take the reference from this url [http://www.musicalgeometry.com/?p=1681] and use that onr Capture camera view and onverlay in an image

如果我的代码有任何错误，请指导我.

Please guide me if any mistake on my code.

谢谢.

推荐答案

请尝试替换以下行:

 [overlayGraphic drawInRect:CGRectMake(30 * xScaleFactor, 100 * yScaleFactor,
 overlaySize.width * xScaleFactor, overlaySize.height * yScaleFactor)];

与此行

[overlayGraphic drawInRect:CGRectMake(0, 0, finalSize.width, finalSize.Height)];
