Although Java 2D works fairly well (although with some annoying bugs on Mac OS X) and offers a simple and consistent API, there's still some features I'd really like to see added:
- Color quantization, first and foremost. I want to be able to convert a full color image to a 4-, 16- or 256-color pallette and then save it in GIF- or PNG-format. Currently I use the command-line pngquant program as an alternative solution.
- Configurable character spacing. Currently, character spacing (not character width) is fixed.
