Editing GIMP (section)

=== Automation, scripts and plug-ins ===
GIMP has approximately 150 standard effects and filters, including Drop Shadow, Blur, Motion Blur and Noise.

GIMP operations can be automated with [[scripting language]]s. The Script-Fu is a [[Scheme (programming language)|Scheme]]-based language implemented using a [[TinyScheme]] interpreter built into GIMP.<ref>{{cite web |title=Using Script-Fu Scripts |url=http://docs.gimp.org/2.8/en/gimp-concepts-script-fu.html |website=Docs.Gimp.org |access-date=26 May 2014 |archive-date=7 June 2014 |archive-url=https://web.archive.org/web/20140607075758/http://docs.gimp.org/2.8/en/gimp-concepts-script-fu.html |url-status=live }}</ref> GIMP can also be scripted in [[Perl]],<ref>{{cite web |title=Basic Perl |url=http://www.gimp.org/tutorials/Basic_Perl/ |website=Gimp.org |access-date=26 May 2014 |archive-date=27 May 2014 |archive-url=https://web.archive.org/web/20140527220212/http://www.gimp.org/tutorials/Basic_Perl/ |url-status=live }}</ref><ref>{{cite web |title=GIMP Perl source |url=https://git.gnome.org/browse/gimp-perl |website=GNOME git repository |access-date=26 May 2014 |archive-date=23 December 2014 |archive-url=https://web.archive.org/web/20141223004855/https://git.gnome.org/browse/gimp-perl/ |url-status=live }}</ref> [[Python (programming language)|Python]] (Python-Fu),<ref>{{cite web |title=GIMP Python Documentation |url=http://www.gimp.org/docs/python/ |website=Gimp.org |archive-url=https://web.archive.org/web/20140615063302/http://www.gimp.org/docs/python/ |archive-date=15 June 2014 |access-date=26 May 2014}}</ref><ref>{{cite web |title=GIMP Python source |url=https://git.gnome.org/browse/gimp/tree/plug-ins/pygimp/plug-ins |website=GNOME git repository |access-date=26 May 2014 |archive-date=7 August 2011 |archive-url=https://web.archive.org/web/20110807023959/http://git.gnome.org/browse/gimp/tree/plug-ins/pygimp/plug-ins |url-status=live }}</ref> or [[Tcl]], using interpreters external to GIMP.<ref>{{cite web |title=Gimp Client |url=http://wiki.tcl.tk/11232 |website=wiki.tcl.tk website |access-date=26 May 2014 |archive-date=27 May 2014 |archive-url=https://web.archive.org/web/20140527212750/http://wiki.tcl.tk/11232 |url-status=live }}</ref> New features can be added to GIMP not only by changing program code (GIMP core), but also by creating plug-ins.

There is support for several methods of sharpening and blurring images, including the blur and sharpen tool. The [[Unsharp masking#Digital unsharp masking|unsharp mask]] tool is used to sharpen an image selectively&nbsp;– it sharpens only those areas of an image that are sufficiently detailed. The Unsharp Mask tool is considered to give more targeted results for photographs than a normal sharpening filter.<ref>{{cite web |title=Sharpening – Unsharp Mask |url=http://www.scantips.com/simple6.html |website=ScanTips.com |access-date=8 August 2009 |archive-date=5 October 2013 |archive-url=https://web.archive.org/web/20131005054153/http://www.scantips.com/simple6.html |url-status=live }}</ref><ref>{{cite web |title=Unsharp Mask |url=http://manual.gimp.org/en/plug-in-unsharp-mask.html |website=GIMP manual |archive-url=https://archive.today/20060502225017/http://manual.gimp.org/en/plug-in-unsharp-mask.html |archive-date=2 May 2006 |access-date=8 August 2009 }}</ref> The Selective Gaussian Blur tool works in a similar way, except it blurs areas of an image with little detail.
