BufferedImage是Java中处理图像的标准方式,可以方便地进行图像的处理和操作。 图像对象和BufferedImage 在Java中,常见的图像对象包括Image、Icon和BufferedImage。其中,Image是一个抽象类,不能直接进行图像操作,而Icon是一个接口用于表示图标。而BufferedImage则是Image的一个子类,可以直接对图像进行像素级的操作,是最常用...

Java将图像转换为BufferedImage Image image = ImageIO.read(new File(file)); BufferedImage buffered = (BufferedImage) image; 在我的程序中,我尝试: final float FACTOR = 4f; BufferedImage img = ImageIO.read(new File("graphic.png")); int scaleX = (int) (img.getWidth() * FACTOR); int sc...
Image to BufferedImage: // 获取 Image 对象的高度和宽度intwidth = image.getWidth(null);intheight = image.getHeight(null); BufferedImage bi =newBufferedImage(width, height, BufferedImage.TYPE_INT_RGB); Graphics g = bi.getGraphics();//通过 BufferedImage 绘制图像并保存在其对象中g.drawImage(ima...
