bufferedimage

I was making a program where I load an image and after that I do something with opaque pixels. Transparent pixels showed up as black pixels, but after some time I found the cause:

                                Color c = new Color (input.getRGB(x, y));
    Works->                      if ((input.getRGB(x, y) & 0xFF000000) != 0x00000000) {  do_smth();}
    Returns true at all times->  if (c.getAlpha() != 0) { do_smth(); }

So why it does not work?

How to specify behavior of Java BufferedImage resize: need min for pixel rows instead of averaging

I would like to resize a Java BufferedImage, making it smaller vertically but without using any type of averaging, so that if a pixel-row is "blank" (white) in the source image, there will be a white pixel-row in the corresponding position of the destination image: the "min" operation. The default… >>> More

Hi, The title says enough I think. I have a full quality BufferedImage and I want to send it through an OutputStream with a low bitdepth.
