Support static map view

[jdlrobson]

This would also support non JavaScript users

Can you give some ideas how this should look like?

I already have some library that create SVG rendition from GeoJSON file by creating two layers within SVG file.

• Shape layers - with lines, points etc.
• Background layer - created by downloading OSM tiles by the server and embeding them as Base64 encoded PNG in SVG (this works well with MediaWiki RSVG renderer)

The library is in JavaScript but it can be rather easily ported to PHP.

Please check if this logic is possible withing MediaWiki:

• User modifies map
• At saving Create Rendition function is called
• The SVG file with same name as map and SVG extension is created (during this process limited number of tiles is downloaded from OSM website <= 16). Curl functions from PHP are used
• Builtin MediaWiki renderer creates JPG from SVG
• Template included in page contains fallback that if JavaScript is disabled or browser is old (IE6) image is included instead of Leaflet object

hey @jakaniew i'm not 100% sure how this would work yet! but a great first step would be to get a simple map png in place (non-dynamic) that is loaded by default and when clicked loads the map.

We could then explore a service where we configure this image to point to some external service who's job it is to generate PNGs (which are potentially saved on a map edit - I'm not 100% sure)

You've definitely got the right ideas and pieces of the puzzle I'm just not sure how the pieces fit together yet! Please feel free to submit something so we can play around with this idea! :)

Create pull request #18 (sorry for messing with indentation in some files)

This is first step of introducing static maps - right now we have SVG maps generated on the fly

Now we have decided how we want to rasterize them to PNG

I see two options:

• Save SVG as file in MediaWiki, then PNG is generated automatically as rendition, and when we use some convention of naming of this kind of assets we can then easily display this image on the page - potential drawback is that if we introduce this to Wikimedia then we will have to deal with automatic upload to Commons
• Use some other MediaWiki mechanism, call rasterizing thread after map save and keeping rendition in some kind of object cache (?) - in this case I don't have experience

OK, as mentioned before created another pull request #19

What do you think we should do further regarding options mentioned in post above?
