New Features
Two PostScript operators, new since OPENSTEP 4.2 (NeXT), enable
antialiased rendering on a per-context basis:
- boolean setantialias -
- When set to true, setantialias invokes an
antialiasing algorithm for marking on a display device. This
algorithm is computationally more expensive that the standard
PostScript algorithm, but results in greater legibility and
smoother appearance on low-resolution display devices. Similarly
to setstrokeadjust, the current value of
setantialias is stored in the graphics state.
-
- When setantialias is active, the behavior of
vector-drawing operations changes so that any partial pixel
coverage produces a translucent result approximating the desired
result. The default setantialias value for window devices
is false.
-
- - currentantialias boolean
- The currentantialias operator returns a boolean value
that indicates whether antialiasing is active for the current
graphics state.
New Features in Rhapsody for PowerPC
- The Macintosh color palette is used in eight-bit pseudocolor
mode.
- The Power PC implementation currently supports "256 colors,"
"Thousands of colors," and "Millions of colors" modes only.
