Introduction [edit]
ImageSizeInfoFunctions is an extension to MediaWiki that gives two parser functions returning width and height size of a given image, available in the wiki.
Its purpose is to make it easier to create a template for resizing an image in percentage instead of absolute size. This is useful for images gallery based on images of the same scale but different size.
Features [edit]
- imageWidth (imgw) returns the image width in pixel.
- imageHeight (imgh) returns the image height in pixel.
Installation [edit]
- Download ImageSizeInfoFunctions.php
- Download ImageSizeInfoFunctions.i18n.php
- Save both files in the new extensions/ImageSizeInfoFunctions directory of your wiki.
- Insert these lines in the LocalSettings.php file:
// Activate ImageSizeInfoFunctions extension include_once('extensions/ImageSizeInfoFunctions/ImageSizeInfoFunctions.php');
Configuration [edit]
no configuration required
Usage [edit]
As for all parser functions:
{{#imgw: [image name] }}
{{#imgh: [image name] }}
Template Example [edit]
This template is useful for scaling the given image by percentage or, as usual, by absolute size:
<includeonly>[[Image:{{{imagename}}}|{{ #if:{{#pos:{{{newwidth|100}}}|px}}|{{{newwidth|100}}}| {{#expr: ({{#imgw: {{{imagename}}} }} * {{{newwidth|100}}}) / 100 }}px }}|{{{caption|}}}]]</includeonly>
Thus, assuming that the template is called ScaleImage:
Scaling the image to 15%:
{{ScaleImage
|imagename=eland.png
|caption=Città di Eland
|newwidth=15
}}
Scaling the image to 80 pixel:
{{ScaleImage
|imagename=eland.png
|caption=Città di Eland
|newwidth=80px
}}
