## set antialias

`set antialias on` | `off`

This command, which is available in GrADS version 2.1+, allows the user to disable or enable anti-aliasing.

### Usage Notes

When using GrADS version 2.1+ with the Cairo graphics library, anti-aliasing is enabled by default. This command does not "stick" -- anti-aliasing resets to "`on`" with `clear`, `reset`, and `reinit`. For some applications it may be desireable to disable this feature, but in general anti-aliasing improves the appearance of the graphics and should be left on.
