AWSwitch: Switch between 16, 64 and 128 levels of anti-aliasing!

Normally, ArtWorks files are rendered using 16 levels of anti-aliasing. For most applications, in particular for on-screen viewing, this is quite adequate. However, for high-quality bitmap output, this is not optimal. The free AWSwitch utility allows you to switch between 16, 64 and 128 levels of anti-aliasing.

16 levels of anti-aliasing

128 levels

128 levels of anti-aliasing

Please note that the difference between the screen shots may not be obvious unless you are using a screen mode with 256 greys or 16 million colours.

The bottom example would probably look identical with 64 levels or with even more levels. An almost horizontal line with a very slight slope would be needed to exploit a larger number of levels.

Please note that using 64 or 128 levels of anti-aliasing as opposed to 16 slows down the rendering of ArtWorks files by about 10% - this is the price for the higher quality and this is also the reason why the standard number of anti-aliasing levels is still 16. The difference between 16 and 64 is quite noticeable when you magnify the output, but at normal screen resolution, it is difficult to see.

128 levels is the maximum number that is possible without major changes in GDraw. However, it would not make sense to have more than that anyway because the theoretical maximum of anti-aliasing levels that can be displayed, even in a 16 million colour mode, is only 256. However, due to the way anti-aliasing works - there is only a one pixel thin border of anti-aliasing around each object - even the difference between 128 and 256 levels is almost non-existent. Even other applications that claim to offer more levels never display these on screen but only use them when outputting to formats that support even more than 16 million colours.
