This would be better for charts, graphs, and diagrams that might need to be tweaked, as the SVG could be saved, altered by hand or in an SVG-capable vector editor, and simply re-uploaded without requiring that the original author do the tweak, provide the original vector file as a second upload, or requiring subsequent editors to own a proprietary graphics editor. </p><p>Additionally, vector images scale better when printed; a "printable version" can rasterize at a higher resolution for browsers that don't <a href="https://en.wikipedia.org/wiki/grok" class="extiw" title="en:grok">grok</a> SVG natively. </p><p>For rasterized images produced by MediaWiki's SVG rendering engine for display in articles, the free code image format is <a href="https://en.wikipedia.org/wiki/Portable_Network_Graphics" class="extiw" title="en:Portable Network Graphics">PNG</a>. </p> <meta property="mw:PageProp/toc"/> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Possible_kinds_of_SVG_support" data-mw-thread-id="h-Possible_kinds_of_SVG_support"><span data-mw-comment-start="" id="h-Possible_kinds_of_SVG_support"></span>Possible kinds of SVG support<span data-mw-comment-end="h-Possible_kinds_of_SVG_support"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=SVG_image_support&action=edit&section=1" title="Edit section: Possible kinds of SVG support"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>There are several levels of SVG support that we might hope for in Wikipedia. </p> <ol><li>Simple storage for download. This would permit users creating diagrams to upload “source” along with the PNG so that, for example, people could translate all the text to a new language. Currently disabled for fear of encountering an SVG image that contains <a href="https://en.wikipedia.org/wiki/malware" class="extiw" title="en:malware">malware</a>.</li> <li>Storage and rendering on the server. This would save time and trouble for uploaders, especially since scaling raster diagrams is a pretty dubious operation. Currently implemented and active. Requires a usable batch-rendering program on the server; no free program seems to do an adequate job of supporting SVG at the moment (although <a href="https://en.wikipedia.org/wiki/Inkscape" class="extiw" title="en:Inkscape">en:Inkscape</a> is promising, since many users will be using it to produce images, and it's free). Malware is a concern — not that Inkscape or <a href="https://en.wikipedia.org/wiki/librsvg" class="extiw" title="en:librsvg">en:librsvg</a> have any known vulnerabilities, since they do not support scripting.</li> <li>Serving SVG code untouched for client-side rendering. This could save bandwidth in many cases (and <a class="external text" href="https://commons.wikimedia.org/w/index.php?title=File:Seal_of_the_United_States_Supreme_Court.png&diff=prev&oldid=25138490">use much more</a> if used blindly) and be convenient for users with the correct plugin or Web browser that supports SVG natively. It would also open the door to animated, interactive, scripted SVG on Wikipedia pages — whether this is a good or a bad thing.</li> <li>Serving SVG code untouched <i>and</i> allowing it to be edited wiki-wise. Might be useful for small fixes (such as colour changes or spelling fixes) to simple files or for translation.

This would allow easy updating of diagrams and maps when data changes, for instance. </p><p>Others consider SVG's baroque and tedious XML syntax of little use for manual processing with text editors and HTML forms.

Editings in this name space would be interpreted as a svg image. The preview and the final display would first of all check to make sure that the SVG had the correct syntax, and then it would display a PNG and the SVG of the image. When the editing was done a PNG would be generated from the svg and placed in a generated images directory. The SVG would be edited as text, or could be copy and pasted into the editing box. </p> <dl><dd>I like this! You could also have a user option to display the SVG directly, which you might pick if you know that your browser handles SVGs well. -- <a href="/wiki/User:Toby_Bartels" title="User:Toby Bartels">Toby Bartels</a> 18:09 1 Jul 2003 (UTC)</dd></dl> <dl><dd><dl><dd>Yeah. People should be able to choose if they are getting PNG when they know their browser supports SVG.

If the file is a SVG, then a generated image would be created from it. Then when a SVG image is linked, it would generate the appropriate object tag and the secondary link to the generated image. </p> <dl><dd>This, in contrast, isn't really any better than any other image format, since it's unclear to people that they can edit the image in the wiki way. -- <a href="/wiki/User:Toby_Bartels" title="User:Toby Bartels">Toby Bartels</a> 18:09 1 Jul 2003 (UTC)</dd></dl> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="Current_implementation" data-mw-thread-id="h-Current_implementation"><span data-mw-comment-start="" id="h-Current_implementation"></span>Current implementation<span data-mw-comment-end="h-Current_implementation"></span></h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=SVG_image_support&action=edit&section=10" title="Edit section: Current implementation"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>MediaWiki 1.5 allows use of an external program to rasterize SVG images to PNG for inline use. (SVG still needs to be manually added to the upload whitelist to allow uploads.) </p><p>The Wikimedia sites are currently using a slightly hacked <a rel="nofollow" class="external text" href="http://librsvg.sourceforge.net/">rsvg</a> (to disable loading of sub-images or other resources from the filesystem) as the renderer. The version used is 2.14.0 (<a href="https://en.wikipedia.org/wiki/Cairo_(graphics)" class="extiw" title="w:Cairo (graphics)">cairo</a>-based). </p><p><a rel="nofollow" class="external text" href="https://xml.apache.org/batik/">Batik</a> provides better rendering but is <i>very</i> slow (a large Java-based library) so we're not using it at the moment. Making it a callable daemon may allow using it effectively. </p><p>All Wikia-hosted projects are currently using ImageMagick's convert (the default). This application has some severe limitations in its SVG->PNG conversion abilities, including complete loss of all <a rel="nofollow" class="external text" href="http://grin-optics.org/">gradient</a>-fills and text. All uncyclomedia.org-hosted projects (for example) therefore use Inkscape. The options to select each of the various renderers are listed in includes/DefaultSettings.php - copy to LocalSettings.php and edit as required. Note that, when first invoking Inkscape, the web server (user: apache on RH/Fedora-style installations) must have write access to its own home directory so that it may create a pair of hidden subdirectories to store Inkscape's settings. Once these directories have been created, no further changes are required. </p><p>A same-image comparison (<a href="/w/index.php?title=As_of_2006&action=edit&redlink=1" class="new" title="As of 2006 (page does not exist)">as of August 2006</a>, based on various MediaWiki 1.7alpha, MediaWiki 1.8alpha installations): </p> <dl><dd>RSVG: <del><a class="external free" href="https://fr.wikipedia.org/wiki/Image:Lapinrose_ratp.svg">http://fr.wikipedia.org/wiki/Image:Lapinrose_ratp.svg</a></del> (transfered from fr.Wikipedia to Commons, then deleted from both wikis due to copyright violation)</dd> <dd>ImageMagick: <a rel="nofollow" class="external free" href="http://desencyclopedie.com/wiki/Image:Lapinrose_ratp.svg">http://desencyclopedie.com/wiki/Image:Lapinrose_ratp.svg</a></dd> <dd>Inkscape: <a rel="nofollow" class="external free" href="http://desencyclopedie.org/wiki/Image:Lapinrose_ratp.svg">http://desencyclopedie.org/wiki/Image:Lapinrose_ratp.svg</a> ( <a href="/w/index.php?title=Inkscape_on_Win32_Server&action=edit&redlink=1" class="new" title="Inkscape on Win32 Server (page does not exist)">Inkscape on Win32 Server</a> Setup Notes )</dd></dl> <p>The image should display as a pink bunny with one hand caught in a subway train door (from <a href="https://fr.wikipedia.org/wiki/Lapin_du_m%C3%A9tro_parisien" class="extiw" title="fr:Lapin du métro parisien">a warning sticker on the Paris métro system</a>).
