I have some bitmapped images of characters I scale down and draw onto a Graphics2D object. I am losing detail and the characters are hard to read.
There is no perfect solution, but here are some suggestions: 1) If you are not already, use one of the interpolation RenderingHints, e.g. VALUE_INTERPOLATION_BICUBIC 2) Instead of scaling in one go, do multiple passes over the image, scaling down a little bit each time. This should eliminate some of the aliasing. 3) Use Image.getScaledInstance using the SCALE_AREA_AVERAGING hint. Be aware that this is deprecated/discouraged/something similarly negative, and quite slow. 4) Vote for this bug to get better downscaling interpolation methods added to the JDK: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6500894 and then wait a few years.
