File Path
byte[] image = JpegAutorotate.rotate("path/to/directory");File
byte[] image = JpegAutorotate.rotate(new File("path/to/directory"));InputStream
byte[] image = JpegAutorotate.rotate(new FileInputStream(new File("path/to/directory")));The library throws the following exceptions:
JpegAutorotateExceptionFileNotFoundException- Only thrown if loading image by either a
