Method

ImageIconcreateMonoColoredImageIcon(final Paint paint, final int width, final int height)
Creates a rectangular mono colored image. 
final BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_4BYTE_ABGR_PRE);
final Graphics2D g = image.createGraphics();
g.setPaint(paint);
final int lineHeight = 4;
g.fill3DRect(0, height / 2 - lineHeight / 2, width, lineHeight, false);
g.dispose();
return new ImageIcon(image);
ImageIconcreateNonCachedImageIcon(File file)
ImageIcon's constructors use MediaTracker to load an image, which is cached. 
try {
    return new ImageIcon(ImageIO.read(file));
} catch (IOException e) {
    e.printStackTrace();
    return null;
ImageIconcreateOverlayIcon(Icon baseIcon, ImageIcon overlayIcon)
create Overlay Icon 
BufferedImage result = new BufferedImage(baseIcon.getIconWidth(), baseIcon.getIconHeight(),
        BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = result.createGraphics();
baseIcon.paintIcon(null, g2, 0, 0);
Image overlay = overlayIcon.getImage();
int w = 12;
int h = 12;
int x = baseIcon.getIconWidth() - w;
...
ImageIconcreateScaledImageIcon(byte[] albumArtBytes)
create Scaled Image Icon 
if (albumArtBytes == null) {
    return null;
Image image = new ImageIcon(albumArtBytes).getImage();
BufferedImage bufferedImage = new BufferedImage(image.getWidth(null), image.getHeight(null),
        BufferedImage.TYPE_INT_RGB);
Graphics graphics = bufferedImage.getGraphics();
graphics.drawImage(image, 0, 0, null);
...
ImageIconCreateSizedImageIconScaledSmooth(URL filePath, int width, int height)
Scales the provided image to the new height/width 
ImageIcon newImageIcon = new ImageIcon(filePath);
Image image = newImageIcon.getImage();
image = image.getScaledInstance(width, height, Image.SCALE_SMOOTH);
newImageIcon = new ImageIcon(image);
return newImageIcon;
FilecreateTempImage(ImageIcon icon, File oldFile)
create Temp Image 
String extension = icon.getDescription();
extension = extension.substring(extension.lastIndexOf(".") + 1);
try {
    File ret = File.createTempFile("cdb", "." + extension);
    ret.deleteOnExit();
    BufferedImage bi = new BufferedImage(icon.getIconWidth(), icon.getIconHeight(),
            BufferedImage.TYPE_INT_RGB);
    Graphics2D g2d = bi.createGraphics();
...
voiddisplayImage(final ImageIcon ii)
Display a given image in a frame (for debuging purpose). 
final JFrame jf = new JFrame();
jf.add(new JLabel(ii));
jf.pack();
jf.setVisible(true);
voiddrawImageBorder(Graphics g, ImageIcon img, Rectangle rect, Insets ins, boolean drawCenter)
draw Image Border 
int left = ins.left;
int right = ins.right;
int top = ins.top;
int bottom = ins.bottom;
int x = rect.x;
int y = rect.y;
int w = rect.width;
int h = rect.height;
...
voiddrawImageBorder(Graphics g, ImageIcon img, Rectangle rect, Insets ins, boolean drawCenter)
Draws a border based on an image. 
int left = ins.left;
int right = ins.right;
int top = ins.top;
int bottom = ins.bottom;
int x = rect.x;
int y = rect.y;
int w = rect.width;
int h = rect.height;
...
ImageIconfitIcon(ImageIcon icon, int containerWidth, int containerHeight)
fit Icon 
if (icon.getIconWidth() > containerWidth) {
    double rate = icon.getIconWidth() / (double) containerWidth;
    int height = (int) (icon.getIconHeight() / rate);
    int width = (int) (icon.getIconWidth() / rate);
    icon = new ImageIcon(getScaledImage(icon, width, height));
} else if (icon.getIconHeight() > containerHeight) {
    double rate = icon.getIconHeight() / (double) containerHeight;
    int height = (int) (icon.getIconHeight() / rate);
...
