Prefiltering Antialiasing For General Vector Graphics

The graphics engines commonly used to draw vector graphics apply the antialiasing technique known as pixel coverage. The quality of the results could be greatly improved through the application of sampling theory. This work presents a simple and practical technique for the rasterization of general vector graphics with correct prefiltering antialiasing: An appropriate antialiasing filter is applied to a continuous model of a shape, and the result is sampled at each pixel position, producing the rasterized output. The use of this technique can significantly enhance the visual quality of most computer applications.

What we are trying to do?

We are attempting to mobilize the creativity and innovative capacities of the Linux and broader open source community to codify the universe of preexisting inventions in defensive publications that upon publication in the IP.COM database will immediately serve as effective prior art that prevents anyone from having a patent issued that claims inventions that have already been document in a defensive publication. In addition to creating a vehicle to utilize this highly effective form of IP rights management for known inventions, it is hoped that the community will use defensive publications as a means of codifying future inventions should the inventors prefer not to make their invention the subject of a patent disclosure and application.
