Resize ImageIcon

[Gregg Bolinger]

Does anyone know if there is a way to resize an ImageIcon when placing it on a Button so that I don't have to physically rezize the image file?? I am writing an Application, not an applet, so the getImage method won't work.
Thanks for any help!!

Ok, here's one way of doing it.
You load your image straight into the ImageIcon using the constructor that takes a file name as an argument like:
ImageIcon icon = new ImageIcon("whatever.jpg");
Make sure the reference you create is an ImageIcon reference. Then use getImage() to grab the image from the ImageIcon:
Image img = icon.getImage();
Now create a buffered image the same size as the image:
BufferedImage bi = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB);
Then blit the icon image to the buffered image, and resize it as you do so:
Graphics g = bi.createGraphics();
g.drawImage(img, 0, 0, WIDTH, HEIGHT, null);
(The code above may be incorrect - check the docs)
Now recreate the IconImage with the new buffered image:
IconImage newIcon = new IconImage(bi);
Hope that helps.

Oh man. You are a saint. Thank you so much!!!
The code was correct by the way too.

I have another problem now. I resized the image, and set it to the new ImageIcon, but I have to actually position the image on the button.

int imageW = imageview.getWidth(); //My Button width
int imageH = imageview.getHeight();//My button height

Image img = myIcon2.getImage();
BufferedImage bi = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB);
Graphics g = bi.createGraphics();
g.drawImage(img, 140, 199, imageW, imageH, null, null);
newIcon = new ImageIcon(bi);

the 140, 199 is positioning the Image on the button. If I set it to 0, 0, the image is off the button somewhere and can't be seen.
Does that make since? I just don't know why it doesn't center the image with the ImageIcon like normally.

I found a better way to do this:

Image img = myIcon2.getImage();
Image newimg = img.getScaledInstance(230, 310,  java.awt.Image.SCALE_SMOOTH);
newIcon = new ImageIcon(newimg);

JButton button = new JButton(new ImageIcon(((new ImageIcon("images/pic.jpg")).getImage()).getScaledInstance(30, 30, java.awt.Image.SCALE_SMOOTH)));
