This module provides utility for wrappers of {{Main page image}}.
Usage
{{#invoke:Main page image|width|ImageTitle}} Get image width from ImageTitle.
ImageTitle must not contain the namespace prefix (eg "File:"). You can use Template:T to strip it, if it exists, when sanitising template params. Example: {{#invoke:Main page image|width|{{Remove file prefix|{{{image}}}}}}}
local p = {}
local getArgs = require('Module:Arguments').getArgs
function p.width(frame)
local args = getArgs(frame)
return p._width(args)
end
function p._width(args)
local new_width = 140 -- square image width
local page = mw.title.makeTitle('File', args[1])
if not page.fileExists then
return new_width
end
local ratio = page.file.width / page.file.height
if ratio > 1.2 then -- consider images with aspect ratio 5:6 - 6:5 as "basically square"
new_width = 160 -- tall image width
elseif ratio < 0.8333 then
new_width = 120 -- long image width
end
return new_width
end
return p
