Mô đun:Imagesize/tài liệu

This module is adapted from the 'getdimensions' function in Module:Multiple image for use as a stand-alone.

It has four public functions: getWidth, getHeight, getDimensions, getScale. They take a filename, with or without the "File:" prefix, and return the width, the height, both dimensions (WIDTHxHEIGHT), or the ratio of width to height (multiplied by a scale factor) respectively. It works with files on Commons or local ones, and works with animated gifs using the dimensions of the first image.

The getScale function takes an additional parameter, |scale= (default is 1). This can be used to directly scale images to the same height using the |upright= parameter in image syntax.
