I want to load an image from my computer into 2D Graphics so that I can edit it afterwards and then I want to add it to JPanel. If you need to see my project I can send it to you. void loadImage() { FileDialog fd = new FileDialog(new Frame(), "Please choose a file:", FileDialog.LOAD); fd.show(); if (fd.getFile() != null) { File fil = new File(fd.getDirectory(), fd.getFile()); strDirectory = fd.getDirectory(); strFileType = fd.getFile(); mainImage.setIcon(new ImageIcon(fil.toString())); getFileList(strDirectory); checkFileType(strFileType); } } Thanks in advance JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Answer 1

To load your image into the memory, you can use ImageIO.read(File). To edit it afterwards, obtain a Graphics2D instance from it by calling createGraphics(): BufferedImage img = ImageIO.read(yourFile); Graphics2D g = img.createGraphics(); // Draw here on the graphics g.dispose(); You can even turn on anti-alias by setting a RenderingHint before drawing: g.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIASING_ON); Then, to add it to a JPanel, create your custom JComponent and add an instance of that component to your JPanel: public class JImageComponent extends JComponent { private BufferedImage img; public JImageComponent(BufferedImage bi) { img = bi; } @Override public void paintComponent(Graphics g) { g.drawImg(img, 0, 0, this); } }
