Description

The list of methods to do ImageIcon Resize are organized into topic(s).

Method

ImageIcongetResizedImageIcon(ImageIcon sourceImageIcon, int iRequiredWidth, int iRequiredHeight)
The method will scale down the sourceImageIcon in a way that it will fit into the rectangle with dimensions (iRequiredWidth, iRequiredHeight) with the original aspect ratio being preserved. 
int iWidth = sourceImageIcon.getIconWidth();
int iHeight = sourceImageIcon.getIconHeight();
float fWidthResizeRatio = iWidth / (float) iRequiredWidth;
float fHeightResizeRatio = iHeight / (float) iRequiredHeight;
float fResizeRatio = Math.max(fWidthResizeRatio, fHeightResizeRatio);
int iNewWidth = Math.round(iWidth / fResizeRatio);
int iNewHeight = Math.round(iHeight / fResizeRatio);
BufferedImage resizedImage = new BufferedImage(iNewWidth, iNewHeight, BufferedImage.TYPE_INT_RGB);
...
ImageIconresize(ImageIcon icon, int extent)
resize 
return new ImageIcon(icon.getImage().getScaledInstance(extent, extent, Image.SCALE_SMOOTH));
ImageIconresize(ImageIcon image, int width, int height)
resize 
BufferedImage bi = new BufferedImage(width, height, BufferedImage.TRANSLUCENT);
Graphics2D g2d = (Graphics2D) bi.createGraphics();
g2d.addRenderingHints(
        new RenderingHints(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY));
g2d.drawImage(image.getImage(), 0, 0, width, height, null);
g2d.dispose();
return new ImageIcon(bi);
ImageIconresize(ImageIcon src, Dimension size)
resize 
if (src != null)
    return new ImageIcon(src.getImage().getScaledInstance(size.width, size.height, Image.SCALE_SMOOTH));
return null;
ImageIconresize(ImageIcon src, int destWidth, int destHeight)
Resizies an image using SCALE_SMOOTH (slow) 
return new ImageIcon(src.getImage().getScaledInstance(destWidth, destHeight, Image.SCALE_SMOOTH));
ImageresizeImageAspectRatio(int width, int height, ImageIcon orig_img)
Resize image aspect ratio. 
Image img = null;
float disp_aspect_ratio = (height * 1.0F) / width;
float aspect_ratio = (orig_img.getIconHeight() * 1.0F) / orig_img.getIconWidth();
if (aspect_ratio == disp_aspect_ratio) {
    img = orig_img.getImage().getScaledInstance(width, height, 0);
} else if (aspect_ratio < disp_aspect_ratio) {
    img = orig_img.getImage().getScaledInstance(width, (int) (height * aspect_ratio / disp_aspect_ratio),
            0);
...
ImageIconresizeImageIcon(ImageIcon icon, int width, int height)
Resize the input ImageIcon to a new size 
BufferedImage buffered = convert(icon);
BufferedImage resized = resizeImage(buffered, width, height);
ImageIcon result = new ImageIcon(resized);
return result;
ImageIconto50x50(ImageIcon imageIcon)
tox 
return resizeTo(imageIcon, new Dimension(50, 50));
