@Override
public void write(IIOMetadata streamMetadata, IIOImage image, ImageWriteParam param) throws IOException {
  RenderedImage img = image.getRenderedImage();
  if (stream == null) {
    throw new IOException("Set an output first!");
  }

    sourceRegion = sourceRegion.intersection(param.getSourceRegion());
  }
  Raster raster = img.getData(sourceRegion);
  int quality = 85;
  if (param.getCompressionMode() == ImageWriteParam.MODE_EXPLICIT) {
    quality = (int) (param.getCompressionQuality() * 100);
  }
