将BufferedImage转换为另一种类型

Question

The most convenient method to read an image from a source ( File s, InputStream s, URL s) is:

BufferedImage myImage = ImageIO.read( source );

But then, how to convert myImage to a BufferedImage.TYPE_USHORT_565_RGB format?

Answer 1

You can create a new BufferedImage of the required type and then draw the original image on it, something like:

    BufferedImage bufImg = ImageIO.read( imageURL );
    BufferedImage convertedImg = new BufferedImage(bufImg.getWidth(), bufImg.getHeight(), BufferedImage.TYPE_USHORT_565_RGB);
    convertedImg.getGraphics().drawImage(bufImg, 0, 0, null);
