其中,"path/to/save/"是保存图像的目录路径,"image.png"是保存的文件名,可以根据需要修改。 调用ImageIO类的write方法将BufferedImage对象保存到文件中: 代码语言:txt 复制 try { ImageIO.write(image, "png", file); } catch (IOException e) { e.printStackTrace(); } 其中,第一个参数是要保存的Buffered...

BufferedImage image= ImageIO.read(newFileInputStream(imgPath) );//保存图片File outputfile =newFile("save.png"); ImageIO.write(bufferedImage,"png", outputfile); 创建BufferedImage对象: //指定宽高、创建带灰色的对象BufferedImage image =newBufferedImage(width, height, BufferedImage.TYPE_BYTE_GRAY...
BufferedImage image = ImageIo.read(new FileInputStream(filePath)); 二、读写 File outputfile = new File("save.png"); ImageIO.write(bi,"png",outputfile); Raster和ColorModel对象、BufferedImage的创建与保存 ImageIO 提供read()和write()静态方法,读写图片,比以往的InputStream读写更方便。
