Short notation for the SVG created with ... templates and Created with ... templates, helps to display

  • W3C validation
  • SVG tool
  • optional: SVG code used for creation
    WWWWwand a great number of other taggings
    formatted within one single line.

Categorisings occur depending on tool name, validation and other tags.


{{Image generation}}

Or use the shorthand {{Igen|… parameters as described …}} (like magyarul "igen" = "yes")

See also the template {{Creation}} for simpler usages within the Information box.

Script support

A user-script has been developed to help you maintaining the file description. Simply paste the following three lines into your common.js (or other MediaWiki skin related) JavaScript page. You can also edit this (script page) per user-preferences:
// [[User:Perhelion/simpleSVGcheck.js]]
if (mw.config.get('wgNamespaceNumber') === 6 && /SVG/i.test(mw.config.get('wgTitle').slice(-3)))

The offered script support enables users – even novice users! – to use the template without knowing all details of its parametrizing.
The script cares for the most essential settings, and does a lot of standardizing the file descriptions when they are in need of being tidied up.
Expert users can complete the suggestions made from the script (e.g. by adding more tags) before saving the script’s changes of the file description page.

Other tags

Can be set either by a shorthand notation, or expressed like in the following examples:

Parameter settings

The flexibility of parameter definition allows to use the template with high variability. The same result can be achieved by different settings.
All parameters are optional; when used, unnamed

  • parameter #1 0 contains either
  • tool name abbreviation letter (default: I for Inkscape)
  • tool name
  • parameters %, ~, !, ?, §, &, <, ^, > or sign $, +, - and more.
  • parameter #2 0 contains either
  • v, n, s,
  • numeric error count (W3C),
  • parameters %, ~, !, ?, §, &, <, ^, > or sign $, +, - and more.
See also #Parameter 2
  • parameter #3 to #9 contains each one either
  • parameters %, ~, !, ?, §, &, <, ^, > or sign $, +, - and more.

Template parameters

1Name of the tool (case sensitive) to get the template name "Created with {{{1}}}"

Abbreviation of the tool name, case-insensitive:

Note: "A$" abbreviates for "Adobe and Commonist"

ww"IA" abbreviates for the mixture Inkscape & Adobe
ww"Im" abbreviates {{Inkscape|…|IMPORTANT=yes}}
ww"ItB" abbreviates {{Inkscape to Bitmap}}
2either character "v" (valid) (if absent, v is assumed with SVG files)
or   the numeric error count from W3C validation ("0" ≘ "v", "-1" ≘ unckeckable)
or   character "s" to suppress the W3C-box for SVG files (but with error count e=)
See the detailed information for parameter #2 and suppress W3C
3[1]necessary because the template cannot determine from where it is transcluded:
  • a "-" (minus sign) to terminate the left-floating with {{clr}}
    Can be necessary if the template is used outside the {{Information}} box
  • a "+" (plus sign) when used in |Other fields or |Other fields 1. In this case
  • parameter fn= may specify a field name for {{Information field}}

Note: when a field name is specified, parameter "+" is implied and can be omitted;

Note2: otherwise the field name "development" is nationalized by {{I18n/COA}}
4[1]a "$" (dollar sign) when "Commonist2.svg Uploaded with Commonist" should be added. In this case
  • parameter $u= may specify a user, e.g. {{U|user}}
  • parameter $l= may specify a logo (☭), e.g. [[File:xyz.svg|20px]]
  • parameter $t= may specify a text, e.g. &nbsp; explanation
  • parameter $c= may specify a category, e.g. [[Category:Othercat| ]]
  • parameter $s= may specify a subcategory, e.g. :diffusion
  • parameter $w= may specify a topic, e.g. m or projection
  • parameter $f= may specify a linefeed, e.g. <br>, none = n (default: {{clear}})
If any one of these seven parameters is specified the "$" is implied and can be omitted.
5[1][2]For additional parametrizing see individual information
  • a "%" (percent sign) or "%v" to insert the {{Translate}} tag, "%s" when option <switch>.
  • a "~" (squiggle sign) to insert the {{pgf-Cdata}} tag.
  • an "!" (exclamation mark) to insert the {{BadSVG}} tag.
  • a "?" (question mark) to insert the {{Rsvg bug}} tag.
  • a "§" ("section" sign) to insert the {{TracedSVG}} tag.
  • an "&" (ampersand) to insert the {{QGIS}} tag.
  • a "<" ("less" sign) to insert the {{Path text SVG}} tag.
  • a "^" (circumflex sign) to insert the {{Quality image}} tag.
  • a ">" ("greater" sign) to inhibit for large SVG the "show source" option of the W3C validator.
  • a "\" (backslash sign) to insert the {{Superseded}} tag.
e[rr]when invalid SVG: error count from W3C validation ("0" for valid, "-1" for uncheckable)

(has precedence over any argument of parameter 2)

Note: when uncheckability is specified, always Other tools is implied.
m[ore]optional additional text (use M= to precede that text with a space).optional

  • sc=/s:=, sm=/s-= (lower case) with insertions, see #Subcat & topic
  • s=  (lower case) can be used instead, or in addition to all the above;
With a one-letter-code for s= the topics-subcategory may be defined, as
:CoA, :Diagrams, :Flags, :Icons, :Logos, :Maps, :Signs, :Unicode, :Trigonometry,
When sub/S and s are both defined, sub/S is used for subcategorizing,
and s is used (like w) as an information and topic for several subtemplates

Additional information

The template is intended to be used in the following namespaces: the File namespace

The template is intended to be used by the following user groups: all users


This template is not intended to be localized.

The template is intended to be used within the {{Information}} box, e.g. at Other fields=, or anywhere outside

Because the prevalent majority of files belongs to Valid Inkscape, 1=Inkscape and 2=v are the default values

The template uses several specific subtemplates, e.g. {{Nil2}}, {{I18n/COA}}, {{Igen/amp}} {{Igen/bug}}, {{Igen/clt}}, {{Igen/fif}}, {{Igen/lab}}, {{Igen/par}}, {{Igen/qui}}, {{Igen/sub}}, {{Igen/top}}, {{Igen/twt}}, {{Igen/upl}}, {{Igen/2nd}}, {{TextSVG-s}}, {{Translate-s}}, {{BadSVG-t}}, {{Created with X}} and more.
Subtemplating allows swift maintenance while the main template is locked for protection.

The template and its subtemplates are using several internationalization methods, like {{autotranslate}} and {{LangSwitch}}.

Additional notes

  1. a b c Every one of the signs ($, +, -) or parameters (%, ~, !, ?, §, &, <, ^, >) can be passed in any sequence, each as an argument for one of the unnamed parameters #1 through #9.
  2. Every one of the eight signs can be used either as a positional parameter, or as a named parameter passing the value to the corresponding template; see Named and unnamed parameters.
  3. a b c d e f This parameter allows supression with the parameter value "-"

Because letters are used for the abbreviation of tool names, parameters #1 to #9 use other characters.

Parameter table

The table shows for some given simple situations one of several possibilities to set parameters:

  • if the tool needs to be specified, it’s only possible with parameter #1
  • an error number can be specified either with parameter #2, or everywhere with err=
  • the n at parameter #2 clarifies that the file is non-SVG
  • to tag a file which is not SVG the n needs to be set with parameter #2
  • when used as argument of Other fields, the + is necessary
  • when used outside the information box, the - may be necessary
placement other fields standalone
parameters p1 p2 p3 p40 p1 p2 p3 p40
valid Inkscape +
Inkscape 1 error + 1 1
valid BKchem B + B
Gnuplot 4 errors G 4 + G 4
Python raster P n + P n
valid PHP PHP + PHP
PHP 17 errors PHP 17 + PHP 17

Parameter 2

Parameter #2 has historically been the place to specify the file’s validation, as in transclusions like {{Inkscape||v}}. Now it may contain one of the following:

  • The character "v" to mark a valid SVG file. Because this is the default for SVG files it is not necessary to be specified and can be omitted.
  • The character "n" to mark a non-SVG file. Because this is the default for non-SVG files it is not necessary to be specified explicitly.
  • The character "s" to mark a SVG file with suppression of the W3C-box. To enable proper category sorting, "e= " must be specified explicitly (e=0 for "valid").
  • The W3C error count: either "0" (for a valid SVG), a number > zero or -1. This error count can also be given with the parameter e=. Default is "0".
  • The value "-1" for SVG code that is impossible to be checked by the W3C validator; "Other tool" is implied, no need to specify it.
  • One of the signs $, +, - or %, ~, !, ?, §, &, <, ^, >. These can also occur as arguments for any one of the unnamed parameters #1 through #9.

Suppress the W3C-box

Parameter #2 set to "n" for raster graphics avoids the W3C-box and enables correct categorizing.
To suppress the W3C-box for SVG files, set parameter #2 to "s". When the SVG file contains W3C-errors, always set the e= parameter, otherwise e=0 to enable correct categorizing and sorting within the category. Setting "s" without "e=" let the file be W3C-unspecified.

If it seems necessary to tag a file with more than one generation tool, the other tool(s) can be added with e.g. t={{Created with ...|err=…|vo=n}}. The validator option vo set to "n" avoids to show the W3C-box again, while err must specify the error count (or "0") to categorize correctly, including the descending sorting within the category in the case of W3C-errors.

Template SimplSVG

To combine both the advantages of SimplSVG and Image generation it is possible to transclude the first one by the second.

This can be done by setting {{ Igen9 = +10 = Sand then the parameters for SimplSVG, followed by them for Image generation }}.

An example may be e.g. File:Non-EU-section-with-MK-2012.svg with {{ IgenI18034272v%+10 = S }},
plus additional positional and named parameters for SimplSVG (like e.g. vs=-),
plus additional positional and named parameters for Igen like e.g. %, vsub= and/or T=.
No conflict can occur with the free-position parameters because SimplSVG uses letters, and Image generation uses other characters.

SVG source code display

Many templates bear the option to show the source code by which the graphics are generated. When used, the files are categorized into the relevant subcategories. This table shows (at column "c") where this option exists. Up to three different codes can be shown; if this is not enough, from each additional invocation of Created with code up to three more codes can be displayed.
If a "Created with …" template does not support the source code option, it is nevertheless possible to let it be displayed by Image generation.
Just invoke the subtemplate Created with code with the "T" parameter:
{{Igen| …|T={{Created with code|l1= |h1= |c1= …}} }}
The documentation explains how the different parameters can be used to format the output; a short reference can be found below.

Subcategory specification

The template offers various possibilities to diffuse a category by subcategories.

  • With sub= a suffix to the category name is specified;
    • when this suffix string needs to be prefixed with a semicolon ":" use the parameter sc= or s:= or sub:=.
    • or when this suffix string needs to be prefixed with a hyphen "-" use the parameter sm= or s-=.
  • An uppercase S= does the same but an in-between space is inserted.
  • Recommended is to use the parameter s= which bears several advantages:
  • With a code of one letter (or an abbreviation of some letters) many predefined subcategories are accessable; the subtemplate Igen/sub cares for the expansion.
  • Such a short code is also used as a topic for the description by many other templates;
    while Igen/sub expands only to subcategory names in English, the subtemplate Igen/top transposes multilingual.

Only in cases where the required topic differs from the subcategory, or no subcategory should come in effect, another code can be defined to substitute the s= value. This topic letter can be defined with the parameter topic= or what/w= and becomes expanded instead. ("w" for what= because the "t" had been used for "trailing text", and cannot be used to abbreviate topic=).
Other subcategories:

!s= for {{BadSVG}}s <s= for {{TextSVG-s}}
?s= for {{Rsvg bug}}s §s= for {{TracedSVG}}
&s= for e.g. {{QGIS}} $s= for {{Commonist}}
gc= for {{Graphic Lab}}-xx


When as well s= and sub= or S= are defined, sub/S is used for subcategorizing (or suppression with sub=-) and s= can then be used like w= for topic specification. The topic option can alse be suppressed with w=-, independent from s/sub/S.
As said above, the parameter s can be used for subcategorizing; when no parameter topic= (or what/w=) is specified the value of s is also used for the topic text by the national versions of the Created with ... templates. Except of this defaulting the two parameters can be defined and/or suppressed completely independent from each other.
These tables show the conversion of s=, and the conversion & translation of w=.

Subcat & topic

It is also possible to define with one single parameter sub-category and topic, with a subcategory-separator semicolon ":" or minus "-".
Parameter values of "sc" and "sm" specify a subcategory; they are prefixd with a ":" resp. a "-", but except that they are used as-they-are.
When there is neither a parameter "topic", "what"/"w", nor "s" then the parameter values of "sc" / "sm" are used also for topics, with their first letter lower-cased, but not translated.

Parameter values of "s:" and "s-": specify a subcategory they are prefixed with a ":" resp. a "-", the first letter is capitalized and a final "s" is added.
Example: s:=digit specifies the subcategory ":Digits" (as is done with s=7).
When there is neither a parameter "topic", "what"/"w", nor "s" then the parameter values of "s:" / "s-" are used also for topics, with their first letter lower-cased, but not translated.
Similar is the result with sub:= but neither case changing nor "s"-adding occurs.
The parameters S: and Sub: are working like s: and sub:, with an additional space after the semicolon.

Named and unnamed parameters

Each one of the following parameter codes can be used either positional to set taggings with extern templates, or they can be used as parameter names to pass an individual information to the templates. The function is like using the templates with the |t= parameter, either without or with an individual information.

  • (positional) "?" can also be written as "t={{SVGbug}}"
  • (named p.) "?=rendering error" can also be written as "t={{SVGbug|description=rendering error}}"
