Incorrect decode of grayscale jpg2000 file #23

Open THausherr opened 6 years ago

BufferedImage bim = ImageIO.read(new File("PDFBOX-4081.jp2"));
ImageIO.write(bim, "png", new File("PDFBOX-4081.png"));

PDFBOX-4081.zip

ZIP file attached that contains both files. The saved file looks "grainy" and the colors are wrong.
