Extension talk:ImageMapConversion

Updated for MW 1.11
I noticed a slight problem with MW1.11 - an error message due to one function (loadMessages) not returning a valid value. It now returns true.

If you choose to upgrade, just download and replace ImageMapConversion_body.php; it's the only one with a change in the code.

What does this extension do?
I am compiling image map resources and info here:
 * commons:Commons:Image map resources

I do not understand what this extension does. How does one use it to convert an image map found on the web to one that can be used on a MediaWiki-based wiki? I figured out how to convert an image map manually, but an automated process would be very helpful. --Timeshifter 01:58, 31 August 2008 (UTC)


 * The extension installs a special page on the wiki. The special page has a text area (with a Browse button) that allows the user to input the path and file name (on the local computer) of a file containing an HTML image map.  It then takes the HTML format image map and converts it to the format required by the Imagemap extension.


 * The conversion is simple, since the HTML formats and the Imagemap formats pretty much map one-to-one. For example, the following HTML:


 * 


 * converts to:


 * poly 520 80 606 56 615 100 565 115 Prince Edward County


 * All that's done is to remove the HTML and the commas and interpret the href and title.


 * The extension can take an entire HTML page file. It will ignore everything before the first image map statement and stop after the closing image map statement (hence it will do only one image map in a file; multiple image maps in one HTML file will require the user to split the HTML file manually).


 * In processing the HTML, it will skip any nasty HTML, preventing the injection of malicious HTML.

 * Thanks for creating this extension. Where is this special page on the Commons or on English Wikipedia? I want to try it out. Does it only work on HTML files saved on my PC? Or can I point the extension to a web page?


 * If I see an image map on a page on the web that I want to convert should I save the web page in 2 parts (the HTML file and the files folder)? Or do I save just the HTML, and then save the image separately?


 * I am a basic webmaster so I know how to separate a web page in 2 parts. But others will not be able to do that. Is there a way to tell the extension to look at the 2nd or 3rd image map on a page? --Timeshifter 01:03, 1 September 2008 (UTC)


 * Wikipedia does not use this extension. You can try it out on my wiki Kayakwiki's pool wiki.  You have to use a file, so if you want to convert a web page, you'd have to capture the page's HTML and save it as a file on your computer.  You'd have to save the image file separately and upload it to your wiki using the usual file upload page.


 * The extension only looks at the first image map on a page. You'd have to manually split it to get a second or third image map.

 * Thanks. I tried saving several web pages with image maps to my PC. Then I browsed to them from within the converter, and clicked "submit." No luck with any of them.


 * http://flagspot.net/flags/ie(.html - The converter seemed just to copy the HTML code without converting it.


 * The only thing that showed up in the results for the rest of the pages was a pound symbol (#), and nothing else. Here are the pages that did that:
 * http://commons.wikimedia.org/wiki/Template:Clickable_map_of_Central_America
