- DEMONSTRATION AVAILABLE -> `AntiAliasing.ademo`
-
- Aliasing is the jaggedness that results when the computer displays diagonal
- or curved lines. The "stair-stepping", as it is also called, is more
- visible in lower resolutions. The AntiAlias effect tries to make the
- jaggedness less apparent. This is achieved by decreasing the contrast
- between an objects jagged edge and the background with intermediate shades
- of color. The AntiAliasing effect automatically places a gradient that
- blends an edge into the background. This effectively gives the illusion of
- a much smoother edge.
-
- There are two levels of AntiAliasing, Low and High. Increasing the level of
- AntiAliasing will provide smoother looking edges but can take more time
- when large areas are involved.
-
- Use the keyboard equivalent,
-
- ALT /
-
- to toggle between None, Low and High AntiAliasing; A lowercase a in the
- menu bar indicates that low AntiAliasing is activated, while an uppercase A
- indicates High AntiAliasing.
-
- Basically, you can use the AntiAliasing effect with most of the drawing
- tools and Built-In brushes including:
-
- Dotted,
- Continuous,
- Straight Line,
- Circle,
- Ellipse,
- Polygon,
-
- In addition, stamping down a custom brush with AntiAliasing on, will cause
- the edges of the brush to be smoothed.
-
- AntiAliasing also applies during use of the Move requester.
-
- ** However, in order for AntiAliasing to work during a move, you must
- call the Move requester and stamp down the brush's initial position
- while you are in `Perspective` mode.
-
- SEE ALSO -> `Smooth Mode`
-
- The major difference between using AntiAlias and Smooth Mode is that
- Smooth Mode tends to blur edges since the gradient effect is used
- between the edge and the background. AntiAlias creates a smoother and
- cleaner edge by concentrating the gradient between the jagged points
- of an edge.
