Editing Ghostscript (section)

== Free fonts ==
There are several sets of [[free software|free]] fonts supplied for Ghostscript, intended to be metrically compatible with common fonts attached with the PostScript standard.<ref>{{cite web |url=http://packages.debian.org/sid/gsfonts |title=Debian package - gsfonts |access-date=2010-04-21}}</ref><ref>{{cite web |url=http://www.ghostscript.com/doc/current/Fonts.htm |title=Fonts and font facilities supplied with Ghostscript |access-date=2010-04-21 |archive-date=2010-06-12 |archive-url=https://web.archive.org/web/20100612151130/http://www.ghostscript.com/doc/current/Fonts.htm |url-status=dead }}</ref><ref>{{cite web |url=http://www.sabi.co.uk/Notes/linuxFonts.html |title=Linux fonts (mostly X11) |date=2009-08-15 |access-date=2010-04-21}}</ref><ref name=pcl-urwfonts/> These include:
* A collection of 35 font styles from 10 typeface families contributed by German foundry [[URW++]] in 1996 under the [[GNU General Public License|GPL]] and [[Aladdin Free Public License|AFPL]], which is therefore commonly called the '''URW Base 35 fonts''' or '''URW Core 35 fonts'''.<ref name=urw-core35>{{cite web|author1=ArtifexSoftware|title=urw-base35-fonts|url=https://github.com/ArtifexSoftware/urw-base35-fonts|website=GitHub|access-date=25 March 2018|language=en}}</ref><ref>{{Citation |url=http://www.geocrawler.com/archives/3/378/1996/5/0/2064811/ |archive-url=https://web.archive.org/web/20021023155414/http://www.geocrawler.com/archives/3/378/1996/5/0/2064811/ |title=Finally!

*The GhostPDL package (including Ghostscript as well as companion implementations of [[Printer Command Language|HP PCL]] and [[Open XML Paper Specification|Microsoft XPS]]) includes additional fonts under the AFPL which bars commercial use.<ref name=pcl-urwfonts>{{cite web|title=doc/pcl/urwfonts (URW fonts in TTF format)|url=https://ghostscript.com/doc/pcl/urwfonts/|website=ghostscript doc|access-date=24 March 2018|archive-date=25 March 2018|archive-url=https://web.archive.org/web/20180325110208/https://ghostscript.com/doc/pcl/urwfonts/|url-status=dead}}</ref><ref>{{cite web|title=GhostPDL License|url=https://ghostscript.com/doc/pcl/LICENSE|website=ghostscript doc|access-date=21 November 2017|archive-date=25 March 2018|archive-url=https://web.archive.org/web/20180325110208/https://ghostscript.com/doc/pcl/LICENSE|url-status=dead}}</ref> It includes URW++ versions of [[Garamond]] (Garamond No. 8), [[Optima]] (URW Classico), [[Arial]] (A030), [[Antique Olive]], and [[Univers]] (U001), [[Clarendon (typeface)|Clarendon]], [[Coronet (typeface)|Coronet]], [[Letter Gothic]], as well as URW Mauritius and a modified form of [[Albertus (typeface)|Albertus]] known as A028. Combined with the base set, they represent a little more than half of the standard PostScript 3 font complement.
* A miscellaneous set including [[Cyrillic]], [[kana]], and fonts derived from the free Hershey fonts, with improvements by Thomas Wolff (such as adding accented characters).

The Ghostscript fonts were developed in the PostScript Type 1 format but have been converted into the TrueType format.<ref name=urw-core35/><ref name=pcl-urwfonts/> As a result, a user can install and use the Ghostscript fonts via most modern software. Furthermore, the Ghostscript fonts are used as parts of various open source applications, e.g., the Linux version of [[GIMP]] depends on [[Graphviz]] which in turn depends on the Ghostscript fonts.<ref>{{cite web|title=Arch Linux - gimp|url=https://archlinux.org/packages/extra/x86_64/gimp/|access-date=2022-08-04}}</ref><ref>{{cite web|title=Arch Linux - graphviz|url=https://archlinux.org/packages/extra/x86_64/graphviz/|access-date=2022-08-04}}</ref> Finally, multiple open source font projects used glyphs from the Ghostscript fonts, e.g., the Latin characters of [[GNU FreeFont]] are based on [[Nimbus Mono L]], [[Nimbus Roman No9 L]], and [[Nimbus Sans L]].<ref>{{cite web|url=https://www.gnu.org/software/freefont/design-notes.html|title=Gnu FreeFont: Design notes|access-date=2022-07-08}}</ref> The TeX Gyre fonts are also based on 8 out of the 10 original Ghostscript typeface families.<ref>{{cite web|title=The TeX Gyre (TG) Collection of Fonts — GUST Web Presence|url=https://www.gust.org.pl/projects/e-foundry/tex-gyre|access-date=2022-08-04}}</ref> The Garamond font has additionally been improved upon.<ref name="URW Garamond ttf conversions">{{cite web|last1=Bisson|first1=Gaetan|title=URW Garamond ttf conversions|url=http://garamond.org/|access-date=18 August 2015}}</ref>
