// To create a buffered image, see e666 创建缓冲图像 // Flip the image vertically AffineTransform tx = AffineTransform.getScaleInstance(1, -1); tx.translate(0, -image.getHeight(null)); AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE…

A buffered image is a type of image whose pixels can be modified. For example, you can draw on a buffered image and then draw the resulting buffered image on the screen or save it to a file. A buffered image supports many formats for storing pixels.…

This example demonstrates how to convert a byte array of pixel values that are indices to a color table into a BufferedImage. In particular, the example generates the Mandelbrot set in a byte buffer and combines this data with a SampleModel, ColorMod…

An Image object cannot be converted to a BufferedImage object. The closest equivalent is to create a buffered image and then draw the image on the buffered image. This example defines a method that does this. // This method returns a buffered image w…

To draw on a buffered image, create a graphics context on the buffered image. // Create a graphics context on the buffered image Graphics2D g2d = bimage.createGraphics(); // Draw on the image g2d.setColor(Color.red); g2d.fill(new Ellipse2D.Float(0, 0…

// Get a pixel int rgb = bufferedImage.getRGB(x, y); // Get all the pixels int w = bufferedImage.getWidth(null); int h = bufferedImage.getHeight(null); int[] rgbs = new int[w*h]; bufferedImage.getRGB(0, 0, w, h, rgbs, 0, w); // Set a pixel rgb = 0xFF…

// This method returns an Image object from a buffered image public static Image toImage(BufferedImage bufferedImage) { return Toolkit.getDefaultToolkit().createImage(bufferedImage.getSource()); } Related Examples…

其实我一直都是喜欢自己去做图像格式的解码的(目前我自己解码的图像格式大概有15种),但是写本文主要原因是基于CSDN的这个帖子的: http://bbs.csdn.net/topics/390510431     用pictureBox显示一个黑白8bit图像,如何消除颗粒感 用于测试的原始的JPG图像: http://files.cnblogs.com/Imageshop/img01.rar 这个帖子中,作者的需要加载一副灰度的8位的PG格式图像,但是利用.net的Bitmap类加载的图像会出…
