JAVA BufferedImage拉伸图片后,并把修改后的图片重新放入BufferedImage中

Answer 1

你怎么拉伸图片的，你取出数据，修改，改完了再给放回去就可以了啊。

追问

bufferedImage.getGraphics().drawImage(img, 0, 0, width, height, null);

Answer 2

BufferedImage originalImage = 你的原图片

int width = 宽度;
int height = 高度;
BufferedImage newImage = new BufferedImage(width,height,originalImage.getType());
Graphics g = newImage.getGraphics();
g.drawImage(originalImage, 0,0,width,height,null);
g.dispose();
originalImage = newImage;
