Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    BufferedImage bi = new BufferedImage(100, 100, BufferedImage.TYPE_INT_ARGB);
    ImageIO.write(bi, "png", new File("test.png"));
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    BufferedImage img = colorImage(ImageIO.read(new File("NWvnS.png")));
    ImageIO.write(img, "png", new File("Test.png"));
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    BufferedImage image = null;/*www  .  ja v  a 2  s . com*/

    URL url = new URL("URL_IMAGE");
    image = ImageIO.read(url);

    ImageIO.write(image, "jpg", new File("C:\\out.jpg"));
    ImageIO.write(image, "gif", new File("C:\\out.gif"));
    ImageIO.write(image, "png", new File("C:\\out.png"));

    System.out.println("Done");
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    BufferedImage original = new BufferedImage(100, 100, BufferedImage.TYPE_3BYTE_BGR);

    BufferedImage copy = original.getSubimage(10, 10, 50, 50);

    ImageIO.write(copy, "png", new File("Test.png"));
}

From source file:ImageConverterGIF.java

public static void main(String[] args) throws Exception {
    String imageFilePath = "C:/myBmp.bmp";
    String gifFilePath = "C:/myPic.gif";
    File inputFile = new File(imageFilePath);
    BufferedImage image = ImageIO.read(inputFile);
    File outputFile = new File(gifFilePath);
    ImageIO.write(image, "GIF", outputFile);
}

From source file:Main.java

public static void main(String args[]) throws Exception {
    BufferedImage img1 = ImageIO.read(new File("c:/Java_Dev/1.png"));
    BufferedImage img2 = ImageIO.read(new File("c:/Java_Dev/2.png"));
    BufferedImage joinedImg = joinBufferedImage(img1, img2);
    ImageIO.write(joinedImg, "png", new File("c:/Java_Dev/joined.png"));
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    BufferedImage bsrc = ImageIO.read(new File("a.jpg"));
    BufferedImage bdest = new BufferedImage(100, 100, BufferedImage.TYPE_INT_RGB);
    Graphics2D g = bdest.createGraphics();
    AffineTransform at = AffineTransform.getScaleInstance(2, 2);
    g.drawRenderedImage(bsrc, at);/*from  w  w w.j  a v a2  s .co  m*/
    ImageIO.write(bdest, "JPG", new File("b.jpg"));
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    BufferedImage originalImage = ImageIO.read(new File("test.png"));
    int type = originalImage.getType() == 0 ? BufferedImage.TYPE_INT_ARGB : originalImage.getType();

    BufferedImage resizeImageBmp = resizeImage(originalImage, type);
    ImageIO.write(resizeImageBmp, "png", new File("a.png"));

    resizeImageBmp = resizeImageWithHint(originalImage, type);
    ImageIO.write(resizeImageBmp, "png", new File("b.png"));

}

From source file:Main.java

public static void main(String[] args) throws java.io.IOException {
    BufferedImage img = ImageIO.read(new File("input-image.png"));

    BufferedImage rotated = new AffineTransformOp(
            AffineTransform.getQuadrantRotateInstance(3, img.getWidth() / 2, img.getHeight() / 2),
            AffineTransformOp.TYPE_BILINEAR).filter(img, null);

    ImageIO.write(rotated, "PNG", new File("output-image.png"));
}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    Image img = new ImageIcon("test.png").getImage();

    BufferedImage bufferedImage = new BufferedImage(img.getWidth(null), img.getHeight(null),
