Bug #: 30282
Summary: feature request: return aspect ratio of an image
Product: Wikimedia
Version: unspecified
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: Unprioritized
Component: General/Unknown
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
It is common to use the multiple image template
(http://en.wikipedia.org/wiki/Template:Multiple_image) to post post a row of
thumbnails specified to be the same height. The template needs to know the
width of each thumbnail in order to draw a box around them. It has no way to
obtain the dimensions or aspect ratio of the original images. Therefore the
template does not accept height as a parameter. In order to obtain the desired
result, one must manually enter the dimensions of each image and desired height
into a formula that returns the width.
Example:
Instead of entering simply this:
height = 100
One must enter this:
width1 = {{#expr: (100 * 750 / 536) round 0}}
width2 = {{#expr: (100 * 320 / 438) round 0}}
width3 = {{#expr: (100 * 892 / 723) round 0}}
etc.
This is hackish and cumbersome and can mess up formatting if an image is
updated with a different aspect ratio. If there was a way to obtain the
dimensions or aspect ratio of an image then the template could handle this.
