Module:Clean image requires Module:Paramtest.

Cleans an input image to prevent double linking.

This module is a helper module to be used by other modules; it may not designed to be invoked directly. See RuneScape:Lua/Helper modules for a full list and more information. For a full list of modules using this helper click here

Clean imageclean{ file = [string|'no'], width = [string|nil], height = [string|nil], link = [string|nil] }tableUsed to clean up user input; extracts only the file name of the input and returns its own formatted link.

Input is a table with fields:

  • file - the full wikitext to be cleaned. All processing is skipped if file is empty or is the string no.
  • width - width to resize the file to; no default
  • height - height to resize the file to, can be combined with width; no default
  • link - what page to link the file to; no default (file will link to file page), no to link to nothing

-- <nowiki>
-- Removes 'File:' prefix, just in case
-- Replace {{!}} with | instead of preprocessing
-- Turn into a nice wiki file link
