Anti-aliasing improvements - should be non-linear

The biggest area for quality improvement in larger build sizes relates to the anti-aliasing function I think. The curing is non linear with respect to pixel brightness. Example - if the vector line of an edge intersects 50% of a target pixel the brightness setting should be closer to 220 instead of the more obvious 128 you would expect. Any hope of being able to better define this with maybe an external txt file? When done properly the improvement in quality is dramatic.

I think I understand the importance of antialiasing now and the difference it can make in print quality. My first step is to allow AA in a range of 1-5x using a bu-cubic resampling alg.

When you choose the export images option does the software use these images for the build? I wonder if I can do some further post processing on them before starting the build. Is there a way to enable this?

There are 2 main 'modes' of slicing:
If you check the 'export images' checkbox, then the slicer will generate all images and save them to disk. At print time, the build manager will use these pre-sliced images, loaded from disk. If you want to modify the images with a script or external program, you can do it anytime before printing.

If the 'export images' is NOT checked, then the slicer will generate the images on-the-fly during the build process.

As I am so good at creating work for other people, what if CW had image processing plugins to
give users options for experimentation, a bit like gimp plugins.
