|
||
Gaffney at Evans and Sutherland in 1976, evolving through ‘JaM’
|
||
(‘John and Martin’, Martin Newell) at <a href="../X/XEROX-PARC.html"><i class="glossterm">XEROX
|
||
PARC</i></a>, and finally implemented in its current form by John
|
||
Warnock et al. after he and Chuck Geschke founded Adobe Systems
|
||
Incorporated in 1982. PostScript gets its leverage by using a full
|
||
programming language, rather than a series of low-level escape sequences,
|
||
to describe an image to be printed on a laser printer or other output
|
||
device (in this it parallels <a href="../E/EMACS.html"><i class="glossterm">EMACS</i></a>, which exploited
|
||
a similar insight about editing tasks). It is also noteworthy for
|
||
implementing on-the fly rasterization, from Bezier curve descriptions, of
|
||
high-quality fonts at low (e.g. 300 dpi) resolution (it was formerly
|
||
believed that hand-tuned bitmap fonts were required for this task).
|
||
Hackers consider PostScript to be among the most elegant hacks of all time,
|
||
and the combination of technical merits and widespread availability has
|
||
made PostScript the language of choice for graphical output.</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="postmaster.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../P.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="pound-on.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">postmaster </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> pound on</td></tr></table></div></body></html>
