Revision of QuartzCrystal: Antialiasing from Fri, 2008-09-05 00:09

The revisions let you track differences between multiple versions of a post.

QuartzCrystal performs Spatial Supersampling (Antialiasing).

This is not the same thing as OpenGL's "Full-Scene Anti-Aliasing" (FSAA) --- it's better. When you enable Spatial Supersampling, QuartzCrystal renders your composition at the specified multiple of your target size, and then applies a high-quality scaling filter to reduce the rendered image to the intended size.

All parts of your composition get the same supersampling treatment --- not just lines and poly edges (or whatever your video card supports) as is the case with OpenGL FSAA.

QuartzCrystal 1.2

In QuartzCrystal 1.2, the multiplication factor displayed above the Antialiasing slider has been changed to more accurately reflect the antialiasing magnitude, by showing the square of the factor.

For example, in QuartzCrystal 1.0, when Antialiasing is set to "8.0x", it means that the image width is multiplied by 8.0 and the image height is multiplied by 8.0 --- resulting in an image whose area is 64.0 times the target resolution. In QuartzCrystal 1.2, this antialiasing factor shown as "64x".

The underlying antialiasing algorithm has not changed.
