Question

eclipse中bitmap类用不了 需要什么包?

Answer 1

你的想法是想改变图片的像素是吧？

Java代码
public void changePixel(int width, int height, byte[] imgByte) throws IOException {
BufferedImage scrImage = ImageIO.read(new ByteArrayInputStream(imgByte));
BufferedImage newImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
newImage.getGraphics().drawImage(scrImage.getScaledInstance(width, height, Image.SCALE_SMOOTH), 0, 0, null);
}
