Hey, some time back when I was using BeOS, I used a tool that did graphical resizing with an alternative algorith, so that resizing anything always looked real good and sexy....not like Paint Shop Pro and friends that magled vector-type graphics.

But, in looking for that sorta tool now, I don't even know how to search for it.  Does anyone here know what I'm talking about?  Can ya point me at a good resizing tool? Huh

you can do some pretty nice looking image resizing in java, just follow these steps:

create a new BufferedImage the size that you want the new image to be
obtain the graphics context from the new image: newImage.createGraphics()
set this rendering hint: g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BICUBIC) (you could also use BILINEAR)
draw the original image using the graphics object you got from your new image: g2.drawImage(oldImage, 0, 0, newImageWidth, newImageHeight, null);
if you want to save it to a file, its easy as ImageIO.write(newImage, "jpg", new File("resizedImage.jpg"));

for(int i = 1; i > 0; i++)
     System.out.println(i+" cups of java downed");

also, paintshop should resize just fine... maybe you need to change the image format to RGB from indexed color mode. That changes the filtering used in photoshop, not sure about paintshop.

for(int i = 1; i > 0; i++)
     System.out.println(i+" cups of java downed");

Genuine Fractals is a plugin for Photoshop that does  lossless saving in a .stn file format. The format is actually a series of  fractal type formulas so the image can be resized and it looks great. It also compresses the file size quite a bit. Its mostly use for large images, 10 meg +.

Unfortunately it looks like the LE version is no longer available, so you only have a 30 day trial and the full version is $199. I got  the LE version years ago for $25, ver 2.0, they are up to 4.0 now.

For $50 it would be a great plugin to have if you make huge files or would like to do a lot of  resizing. For $199, it seems way over priced unless you are making money with it, or you have piles of cash.
