The ImageSizeInfoFunctions extension provides 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
- imageWidth (imgw) returns the image width in pixel.
- imageHeight (imgh) returns the image height in pixel.
Installation
- Download and place the file(s) in a directory called
ImageSizeInfoFunctionsin yourextensions/folder. - Add the following code at the bottom of your LocalSettings.php file:
wfLoadExtension( 'ImageSizeInfoFunctions' );
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
Usage
As for all parser functions:
{{#imgw: [image name] }}
{{#imgh: [image name] }}
Example
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</nowiki>
|imagename=eland.png
|caption=Città di Eland
|newwidth=15<nowiki>
}}
Scaling the image to 80 pixel:
{{ScaleImage</nowiki>
|imagename=eland.png
|caption=Città di Eland
|newwidth=80px<nowiki>
}}
