Dave, I did a lot of work on anti-aliasing about 18 months ago. Unfortunately, I never finished it. The most significant component that is still outstanding is font handling. I saw two ways to handle fonts: 1. Take the existing fonts but double them along each dimension. Make sure that the font rendering starts off on even x & y coordinates. Then, when the antialiasing code runs it will reduce the characters back to their original shape. The advantages to this approach are: - a font will look *exactly* if antialiasing is turned off and back on. This could be useful because we could turn off antialiasing during rotations. - the same rasterization of a text string would be used whether or not antialiasing was turned on 2. Double the font size when it is rendered. That is, if the person was a 12 pt font then render with a 24 pt font. This will look cleaner and will give better antialiasing. However, the fonts will change if antialiasing is turned off. In addition, this approach would consume more resources because it would be working with much larger fonts and the rasterized strings would be 4 times the size. In addition, I don't think that I ever figured out the best way to deal with a line that is exactly 1 pixel wide. We can't render it 1 pixel wide or it will be very dim. Therefore, they need to be 2 pixels wide, with special care taken to determine where they start and stop. These 2 pixel-wide lines were going to lead to either (a) more branching+code inside the existing line drawing routines .OR. (b) cloning of the line drawing code to create some special purpose 2-pixel-wide line drawing routines. Choice (a) is probably better ... more maintainable. I think about the antialiasing stuff from time-to-time and I hope to be able to get back and finish it up some day when I am able to free up some time to devote to Jmol again.
