I'm trying to save the canvas as a .jpg file using the JPGImageEncoder from com.sun.image.codec.jpeg package; everything seems to work right, but when I open the .jpg file all I get is a black rectangle. Any idea why? Here's some code: Dimension size = canvas_.getSize(); BufferedImage image = new BufferedImage(size.width, size.height, BufferedImage.TYPE_INT_RGB); try { OutputStream out = new FileOutputStream("pic.jpg"); JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out); encoder.encode(image); out.close(); } catch (Exception e) { System.out.println(e); }    More>>
