bufferedimage

I am trying to draw horizontal and vertical lines on a bufferedimage. It should end up looking like a grid of cells. But when I run the code, I see only two lines: the leftmost line and the topmost line (ie. a line from 0,0 to 0,height of image & 0,0 to width of image,0) Heres the code snippet: BufferedImage mazeImage = new BufferedImage(imgDim.width, imgDim.height, BufferedImage.TYPE_INT_RGB); Graphics2D g2d = mazeImage.createGraphics(); g2d.setBackground(Color.WHITE); g2d.fillRect(0, 0, imgDim.width, imgDim.height); g2d.setColor(Color.BLACK); BasicStroke bs = new BasicStroke(2); g2d

I have a problem with Java application, particular in loading a image from a location in my computer. Following this post I used a BufferedImage and a InputFileStream to load an image on my computer. First, I put the image ( pic2.jpg ) into the source code and that is working. However, if I put the image to another place (let's say C:\\ImageTest\pic2.jpg ), Java IDE show me an IllegalArgumentException return ImageIO.read(in); here is the code: public class MiddlePanel extends JPanel { private BufferedImage img; public MiddlePanel(int width) { //img = getImage("pic2.jpg"); img = getImage("C:\

I'm trying to code a class to seam carve images in x and y direction. The x direction is working, and to reduce the y direction I thought about simply rotating the image 90° and run the same code over the already rescaled image (in x direction only) and after that, rotate it back to its initial state. I found something with AffineTransform and tried it. It actually produced a rotated image, but messed up the colors and I don't know why. This is all the code: import java.awt.image.BufferedImage; import java.awt.geom.AffineTransform; import java.awt.image.AffineTransformOp; import java.io.File;

I am trying to convert an image (url below) using two libraries (thumbnailator and imgscalr. My code works on most of the images except a few which after conversion have a pink/reddish tint. I am trying to understand the cause and would welcome any recommendation. Note - Image type of this image is 5 i.e BufferedImage.TYPE_3BYTE_BGR and i am using Java 7 Using Thumbnailator Thumbnails.of(fromDir.listFiles()) .size(thumbnailWidth, thumbnailHeight) .toFiles(Rename.SUFFIX_HYPHEN_THUMBNAIL); Using imgscalr BufferedImage bufferedImage = ImageIO.read(file); final BufferedImage jpgImage; LOG.debug(

Is it possible to create a BufferedImage from a JPanel without first rendering it in a JFrame? I've searched everywhere I can think of and cannot find an answer. Can anyone help? Here is some sample code. If I don't un-comment the JFrame code, my BufferedImage is blank. test(){ // JFrame frame = new JFrame(); JPanel panel = new JPanel(); Dimension dim = new Dimension(50,50); panel.setMinimumSize(dim); panel.setMaximumSize(dim); panel.setPreferredSize(dim); JLabel label = new JLabel("hello"); panel.add(label); // frame.add(panel); // frame.pack(); BufferedImage bi = getScreenShot(panel); //..

I get RGB24 byte array and want to show it in Java. public void getByteArray(byte byteArray[]){ int count1 = 0; byte temp1 = 0; for (int i = 0; i < byteArray.length; i++) { //The order of RGB24 is red,green and blue.Change the //order to blue,green and red so that java can use TYPE_3BYTE_BGR to recognize it if (count1 == 0) { temp1 = byteArray[i]; count1++; } else if(count1 == 1) { //do nothing count1++; } else if(count1 == 2) { byteArray[i - 2] = byteArray[i]; byteArray[i] = temp1; count1=0; } } image = new BufferedImage(width, height, BufferedImage.TYPE_3BYTE_BGR); image.getWritableTile(0, 0

Im working on a paint application written in java and running into a few (more) problems. I have a gui and a working program(kinda), my only problem is that the lines and graphics that the user draws are not saved(disappear after next one is drawn). From a past question i learned that i will need to use a BufferedImage to store the drawings then paint that inside my paint class. My questions are, Can anyone provide a basic explanation/example of how to use a bufferedimage to store and paint the drawing and if i need to, how will i pass the color and thickness of the drawn line into a stored

I'm newbie in jave, my first project is draw, and save a image from JPanel, my draw is done, but I cant save it after I draw in JPanel :(, So can you help me to fix it when I open the image after draw, It doesn't contain anything :( here my codes: package image; import java.awt.BorderLayout; import java.awt.Button; import java.awt.Color; import java.awt.Graphics2D; import java.awt.Point; import java.awt.Graphics; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.awt.event.ActionListener; import java.awt.event.ActionEvent; import java.awt.image.BufferedImage;

I've been trying to convert a ImageIcon to BufferedImage ... And I've had no luck. I have a pre-existing ImageIcon that needs to be converted to a Buffered Image for the vast amount of BufferedImage operations that exist. I have found a few ways, but all of them are hugely CPU intensive. What's wrong with: BufferedImage bi = new BufferedImage( icon.getIconWidth(), icon.getIconHeight(), BufferedImage.TYPE_INT_RGB); Graphics g = bi.createGraphics(); // paint the Icon to the BufferedImage. icon.paintIcon(null, g, 0,0); g.dispose(); See ImageIcon , Image and BufferedImage : ImageIcon yourImage;
