问题 I am trying to find out if reading OpenEXR files are supported or not on iOS and macOS. Here is what I found out: The docs barely mention OpenEXR, and where they do they say that it's only supported on recent macOS. Yet, the official WWDC 2017 samples for ARKit simply load .exr images with: UIImage(named: "image.exr") This is found in the following official samples: Handling 3D Interaction and UI Controls in Augmented Reality Interactive Content with ARKit Audio in ARKit How is OpenEXR

问题 I'm using OpenCV for Android like this to to load an EXR image: String testImgPath = "/storage/sdcard0/test2.exr"; //I know better than to hardcode paths. This is just a test. Mat mRgba = Highgui.imread(testImgPath, Highgui.CV_LOAD_IMAGE_ANYCOLOR|Highgui.CV_LOAD_IMAGE_ANYDEPTH); This works for the first 3 channels of an image (RGB ordering aside). I can display the resulting matrix like this: Bitmap img = Bitmap.createBitmap(mRgba.cols(), mRgba.rows(), Bitmap.Config.ARGB_8888); Utils

To do this I figured that I could use OpenCV as it says in the documentation that it can open OpenEXR format files. I have all the libraries installed and working as I've been doing other things. I open a simple jpg file with openCV cvLoadImage. It works fine. But when i try to open any .exr file it doesn't seam to like it. I get a gray window where there should be the image display.
