[FIXED] How to place two images in one canvas through java (not jframe)

Issue

I just want to place two different images on one canvas and make it a .jpg file in Java. I just want to make a resulting file, not a GUI.

I want to make a result file like below with both images above:

Solution

You can use BufferedImage to combine the two images. The following code shows a simple implementation:

public static void combineImages(String imagePath1, String imagePath2, String outputPath) throws IOException {
    int intervalWidth = 20; // The interval between two images
    BufferedImage image1 = ImageIO.read(new File(imagePath1));
    BufferedImage image2 = ImageIO.read(new File(imagePath2));
    int combinedWidth = image1.getWidth() + image2.getWidth() + intervalWidth;
    int combinedHeight = Math.max(image1.getHeight(), image2.getHeight());
    BufferedImage combined = new BufferedImage(combinedWidth, combinedHeight, BufferedImage.TYPE_INT_RGB);
    Graphics2D g = combined.createGraphics();
    g.setColor(Color.WHITE);
    // Fill the background with white
    g.fillRect(0, 0, combinedWidth, combinedHeight);
    // Draw the two images on the combined image
    g.drawImage(image1, 0, 0, null);
    g.drawImage(image2, image1.getWidth() + intervalWidth, 0, null);
    ImageIO.write(combined, "jpg", new File(outputPath));
}
