This module is rated as ready for general use. It has reached a mature form and is thought to be bug-free and ready for use wherever appropriate. To reduce server load and bad output, it should be improved by sandbox testing rather than repeated trial-and-error editing.

This module contains very few code - but it is heavily used.
It is needed to verify that a given display size is trailed by "px".
It can be expanded to check for other dimensions, as e.g. "em".

it will be used by Template:F, Created with/layout, ...

Use it with e.g. {{#invoke:Dsize|main|{{{sizepar}}} }}

Examples:

{{#invoke:Dsize|main|72px}}	72px	width
{{#invoke:Dsize|main|72}}	72px	width
{{#invoke:Dsize|main|72x}}	72xpx	width
{{#invoke:Dsize|main|x64px}}	x64px	height
{{#invoke:Dsize|main|72x64}} 0	72x64px 0	w × h

Module:Galeria has a similar but more powerful and complex function.

local p = {}
function p.main ( frame )
	local gpar = frame.args
	if  mw.ustring.sub(gpar[1], -2) == 'px' then
		return gpar[1];
	else
		return gpar[1] .. 'px';
	end
end
return p;
