Oriented Images Should Rotate Before Loading

[titanwalking]

After taking a photo from my LG G7 and starting Croppy from the file Uri, CroppyActivity started with the image rotated.

You may consider checking ExifInterface orientation before loading bitmap.

Sample code in Java :

Bitmap rotateBitmap(@NonNull String src, Bitmap bitmap) {
            int orientation;

            try {
                orientation = getExifOrientation(src);
            } catch (IOException e) {
                e.printStackTrace();
                return bitmap;
            }

            Matrix matrix = new Matrix();

            switch (orientation) {
                case ExifInterface.ORIENTATION_FLIP_HORIZONTAL:
                    matrix.setScale(-1, 1);
                    break;
                case ExifInterface.ORIENTATION_ROTATE_180:
                    matrix.setRotate(180);
                    break;
                case ExifInterface.ORIENTATION_FLIP_VERTICAL:
                    matrix.setRotate(180);
                    matrix.postScale(-1, 1);
                    break;
                case ExifInterface.ORIENTATION_TRANSPOSE:
                    matrix.setRotate(90);
                    matrix.postScale(-1, 1);
                    break;
                case ExifInterface.ORIENTATION_ROTATE_90:
                    matrix.setRotate(90);
                    break;
                case ExifInterface.ORIENTATION_TRANSVERSE:
                    matrix.setRotate(-90);
                    matrix.postScale(-1, 1);
                    break;
                case ExifInterface.ORIENTATION_ROTATE_270:
                    matrix.setRotate(-90);
                    break;
                default:
                    return bitmap;
            }

            try {
                Bitmap oriented = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
                bitmap.recycle();
                return oriented;
            } catch (OutOfMemoryError e) {
                e.printStackTrace();
                return null;
            }
        }

private int getExifOrientation(@NonNull String src) throws IOException {
            DebugLog.write();
            ExifInterface exifInterface = new ExifInterface(src);
            return exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
        }

Done. Use version 0.2
