In this case, the camera software should populate the EXIF data with the orientation that the photo should be viewed in.
Here is the rotateImage method:
In this case, the camera software should populate the EXIF data with the orientation that the photo should be viewed in.
Code: Select all
ExifInterface ei = new ExifInterface(photoPath);
int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_UNDEFINED);
switch(orientation) {
case ExifInterface.ORIENTATION_ROTATE_90:
rotateImage(bitmap, 90);
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotateImage(bitmap, 180);
break;
// etc.
}Here is the rotateImage method:
Code: Select all
public static Bitmap rotateImage(Bitmap source, float angle) {
Bitmap retVal;
Matrix matrix = new Matrix();
matrix.postRotate(angle);
retVal = Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(), matrix, true);
return retVal;
}
