Editing Template:Infobox legislation/doc (section)

==Technical information==
{{Mbox|text=This section contains technical information to assist editors familiar with templates and [[:mw:Help:Extension:ParserFunctions|parser functions]] to edit this template.}}

The {{para|image}} parameter in the template contains (with slight modifications) the following function:

<pre style="overflow: auto">
{{#invoke:InfoboxImage|InfoboxImage|image={{#if:{{{image|}}}
  |{{{image}}}
  |{{Infobox legislation/images
     |image={{if empty|{{{legislature|}}}|{{{considered_by|}}}|{{{enacted_by|}}}}}
     |date={{{date_enacted|}}} 
    }}
  }}|size={{{imagesize|}}}|sizedefault=frameless|upright={{{upright|{{{image_upright|1}}}}}}|alt={{{imagealt|}}}}}
</pre>

The function does the following tasks:
* If the parameter {{para|image}} is used in the template, that image is displayed.
* If {{para|image}} is not used, a check is done to see if the value of {{para|legislature}} or {{para|enacted_by}} is listed in {{tl|Infobox legislation/images}}. If the result is blank, then no image is displayed. If the result is an image file (the coat of arms or seal, or a photograph of a building representing the person or institution that enacted the legislation), then the image file is displayed. {{tl|Infobox legislation/images}} can be tweaked to display different images depending on the date when the legislation was decided – for help with this, leave a message on the [[Template talk:Infobox legislation|talk page]].
* If a value is specified for {{para|imagesize}}, the image is given that width; otherwise the image width defaults to "frameless".
* If a value, adds {{para|upright|{{var|value}}}} to image. Values less than 1 scale the image down (0.9 = 90%); values greater than 1 scale the image up (1.15 = 115%).
* In either case the image is given alt text specified by {{para|imagealt}}.

[[User:Jacklee|JackLee]] came up with the first version of this function for {{tl|Infobox court case}}, but thanks are due to [[User:Thumperward|Chris Cunningham]] for coming up with a cleaner solution that works better.
