Hi Randy, Your code snippet looks fine, but I'd suggest using AffineTransformOp.TYPE_BILINEAR rather than TYPE_NEAREST_NEIGHBOR. This filtering method can be more computationally expensive, but produces more visually pleasing results. Note that the image will look slightly blurred, but this is typically more pleasing than a blocky-looking image (like NEAREST_NEIGHBOR produces).
The approach that Rob mentioned will also get the job done just fine (getScaledInstance(SCALE_SMOOTH) uses a bilinear filter), but AffineTransformOp.filter() is more likely to be "natively" accelerated (in Sun's implementation anyway). BTW, you can search the java2d-interest archive online at: http://archives.java.sun.com/java2d-interest.html Thanks, Chris Rob Ratcliff wrote: > Randy, > > I've had good luck with this: > > Image newImage = > oldImage().getScaledInstance(scaledWidth,scaledHeight,Image.SCALE_SMOOTH)); > > At 04:49 PM 10/16/2002 -0500, you wrote: > >> I wasn't able to locate an archive to search so apologize if this is a >> duplicate question. >> I am using an AffineTransform to make an image larger.
