将cameraViewTransform应用于UIImagePickerControllerOriginalImage的最佳方法？ iPhone SDK
我正在尝试将 cameraViewTransform 从我的 UIImagePickerController 应用到 UIImagePickerControllerOriginalImage （来自相机的 UIImage ）。我设法做到这一点的唯一方法是在 UIImageView 上打印 UIImage，然后使用 UIGraphicsBeginImageContext(); 截取屏幕截图UIImageView 我有。
问题是，将 UIImagePickerControllerOriginalImage 打印到 UIImageView，然后缩放和截取屏幕截图需要很长时间来处理，并且还会冻结 iPhone。 （这是因为 UIImage 是全分辨率的，我也希望它保持全分辨率。）
我的问题是......有没有更好的方法来应用 cameraViewTransform 到 UIImagePickerControllerOriginalImage 图像？或者有没有更快的方法在图像视图上打印我的图像？
非常感谢你们的宝贵时间，我真的很感激！ :)
I'm trying to apply the cameraViewTransform from my UIImagePickerController to the UIImagePickerControllerOriginalImage (the out coming UIImage from the camera). The only way I managed to do this is by printing the UIImage on an UIImageView and then using UIGraphicsBeginImageContext(); to take a screenshot of the UIImageView I have.
The thing is, printing the UIImagePickerControllerOriginalImage to an UIImageView, and then zooming and taking a screenshot takes a long time to process and also freezes the iPhone. (That's because that UIImage is in full resolution, and I also want it to stay in full resolution.)
My Question is... is there a better way to apply the cameraViewTransform to the UIImagePickerControllerOriginalImage image? Or is there a faster way to print my image on the image view?
Thank you so much guys for your time, I really appreciate it!!! :)
