Android - Inverted width and height for portrait images

scgough commented 3 years ago

Version

Tell us which versions you are using:

react-native-image-crop-picker 0.36.3
react-native v0.63.3

Platform

Android

Expected behaviour

When selecting a portrait image from the gallery, the width and height should be reported correctly.

Actual behaviour

The width and height are switched. The image is visually correct on-screen (i.e. viewing at the correct dimensions in portrait) but then if you try and process it further in your own app trouble arises from the incorrect dimensions.

Landscape images seem to be fine.

Steps to reproduce

Take a portrait picture on your device
Select it using the picker in this library
Look at the reported width and height 😅

More info

At the moment, I'm not sure if this is a bug with Android itself / by design and I'm not sure if it is isolated to certain makes/models of device. I can reproduce this using Samsung and Google Pixel 4a devices.

I actually think the issue is that the Android camera app applies an orientation of 90 degrees to a portrait image and at some point along the line this causes the width and height to switch. From what I've seen this 'issue' has been around for a looooong time.

Possible work around

I've made this change to the file below and it is working but feels rather hacky....I'd love to get some feedback! It checks for the original image orientation and sets a bool for invertDims to decide what to report back as the width and height in the WritableMap image result.

I've added in getRotationInDegreesForOrientationTag (previously in the Compression.java file).

PickerModule.java

int getRotationInDegreesForOrientationTag(int orientationTag) {
        switch(orientationTag){
            case ExifInterface.ORIENTATION_ROTATE_90:
                return 90;
            case ExifInterface.ORIENTATION_ROTATE_270:
                return -90;
            case ExifInterface.ORIENTATION_ROTATE_180:
                return 180;
            default:
                return 0;
        }
    }

    private WritableMap getImage(final Activity activity, String path) throws Exception {
        WritableMap image = new WritableNativeMap();

        if (path.startsWith("http://") || path.startsWith("https://")) {
            throw new Exception("Cannot select remote files");
        }
        BitmapFactory.Options original = validateImage(path);

        //--- NEW CODE ---
        ExifInterface originalExif = new ExifInterface(path);
        int originalOrientation = originalExif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
        int rotationAngleInDegrees = getRotationInDegreesForOrientationTag(originalOrientation);
        boolean invertDims = rotationAngleInDegrees == 90 || rotationAngleInDegrees == 270;
       //--------------------

        // if compression options are provided image will be compressed. If none options is provided,
        // then original image will be returned
        File compressedImage = compression.compressImage(this.reactContext, options, path, original);
        String compressedImagePath = compressedImage.getPath();
        BitmapFactory.Options options = validateImage(compressedImagePath);
        long modificationDate = new File(path).lastModified();

        image.putString("path", "file://" + compressedImagePath);
        image.putInt("width", invertDims ? options.outHeight : options.outWidth);   //<-- NEW CHECK
        image.putInt("height", invertDims ? options.outWidth : options.outHeight);  //<-- NEW CHECK
       ...

I'm also happy to add a PR for this if the consensus is it should go futher.

Same issue here, in the meantime I downgraded to 0.35.3. It looks like the problem is gone for me.

Tymofiev commented 2 years ago

The same on my environment, if scale a bit - problem disappears. Works fine on version 0.36.0.

GaylordP commented 2 years ago

Same for 0.37.3 :/

vlad-timotei commented 2 years ago

The issue persists in 0.37.3.

I tried to apply @scgough 's patch but I think the patch doesn't apply to the latest code base, as it didn't work any more, but your idea was life saving, so thanks! I tried a similar approach, but also altering the bitmap generated for the original image.

I'm not sure if this approach is the best one, but so far it works on all tested devices. Let me know if this works for you and I could open a PR.

Here's the patch:
