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

推荐答案

你可以新建一个所需类型的BufferedImage，然后在上面绘制原图，比如:

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);
