Description

Area: UIKit

Summary: In iOS 11.x/12.x while cropping an image of photo library using UIImagePickerController is giving wrong value for cropped rectangle found using UIImagePickerControllerCropRect. It happens for high resolution ~(3264X2448).

Steps to Reproduce:

  1. Unzip the attached project TestCameraImage.zip. Open TestCameraImage.xcode project in Xcode 10.2. and run on simulator iPhone 6 having iOS 12.2.
  2. Download attached image originalImage.jpg . Drag image and drop it on simulator iPhone 6 having iOS 12.2.
  3. Launch the app TestCameraImage.
  4. Click on button 'Open'. Select the image originalImage from Photogalary. Do not zoom image.
  5. Click on 'Choose' button.
  6. See the log result on screen. It says - Original image size is ~ {3264, 2448} Edited image size is ~ {750, 560} Crop rect is ~ {0, 0, 3072, 2302}
  7. If we see cropping rectangle in step 4, it has complete image inside. So ideally Original Image size should be approximately equal to crop rect size. But it is different.

Note - In our SDK we are using the UIImagePickerControllerCropRect to give the high resolution edited image.

Expected Results: Original image size should be approximately equal to crop rect size .

Actual Results: Original image has different size than crop rect size as we see in step 6.
