Returns the image type.

Usage

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"));
