server setting for image rotation
When a user uploads an image that is taken in portrait it shows in portrait on my website. I believe this is a setting on the server.
I found this but I am not certain if it is the best method and if it is, I do not know how to implement it. Can we address this in our private session?
//this is the byte stream that I upload.
public static byte[] getStreamByteFromImage(final File imageFile) {
Bitmap photoBitmap = BitmapFactory.decodeFile(imageFile.getPath());
ByteArrayOutputStream stream = new ByteArrayOutputStream();
int imageRotation = getImageRotation(imageFile);
if (imageRotation != 0)
photoBitmap = getBitmapRotatedByDegree(photoBitmap, imageRotation);
photoBitmap.compress(Bitmap.CompressFormat.JPEG, 70, stream);
return stream.toByteArray();
}
private static int getImageRotation(final File imageFile) {
ExifInterface exif = null;
int exifRotation = 0;
try {
exif = new ExifInterface(imageFile.getPath());
exifRotation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
} catch (IOException e) {
e.printStackTrace();
}
if (exif == null)
return 0;
else
return exifToDegrees(exifRotation);
}
private static int exifToDegrees(int rotation) {
if (rotation == ExifInterface.ORIENTATION_ROTATE_90)
return 90;
else if (rotation == ExifInterface.ORIENTATION_ROTATE_180)
return 180;
else if (rotation == ExifInterface.ORIENTATION_ROTATE_270)
return 270;
return 0;
}
private static Bitmap getBitmapRotatedByDegree(Bitmap bitmap, int rotationDegree) {
Matrix matrix = new Matrix();
matrix.preRotate(rotationDegree);
return Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
}
