Question

How would I open a bitmap with Inputstream?

e.g InputStream inputStream = image where image is of type Bitmap?

Thanks.

Answer 1

To read the bitmap image in your app,
BufferedImage img = ImageIO.load("mybitmap.bmp");

To get the pixels from the buffered image object, use getRGB()

int[] pixels = img.getRGB(0, 0, img.getWidth(), img.getHeight(), null, 0, img.getWidth());

javadoc for getRGB().
