    • readWithOrientation

      public static IIOImage readWithOrientation(URL input) throws IOException
      Reads image and metadata, applies Exif orientation to image, and returns everything as an IIOImage. The returned IIOImage will always contain an image and no raster, and the RenderedImage may be safely cast to a BufferedImage. If no registered ImageReader claims to be able to read the input, null is returned.
      Parameters:
      input - a URL
      Returns:
      an IIOImage containing the correctly oriented image and metadata including rotation info, or null.
      Throws:
      IOException - if an error occurs during reading.

    • readWithOrientation

      public static IIOImage readWithOrientation(InputStream input) throws IOException
