将BufferedImage转换为另一种类型

Question

从源(Files,InputStreams,URLs)读取图像最方便的方法是:

BufferedImage myImage = ImageIO.read( source );

但是,如何转换myImage为BufferedImage.TYPE_USHORT_565_RGB格式？

Answer 1

您可以创建所需类型的新BufferedImage,然后在其上绘制原始图像,如:

    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);
