Printing OpenStreetMap maps - new features in render(myMap)

I've added several new features to my OpenStreetMap printing tool, called render(myMap), but never mentioned it in this blog before. You can find some info in my references page or read on.

Source code has been released on SourceForge so the tool is now officially open source. The online "demo" remains live of course, so most users won't need to install their own system, just use

Data is now downloaded from OverPass API instead of the main OSM server (thus uses the "offical way"). Honestly, the data stopped coming from the main server, so I had no other option than rewrite this part. ;-)

And I've added yet another hardcoded limit to: number of maximum printed objects is limited to 5000 per page. Previously the system had only a square km limit. But what worked well for rural areas was completely unreadable in dense cities. Almost all users created unreadable maps, which was very disappointing to me. By adding this limit, I can see people create well printing maps.

Those are the 2018-2019 updates. Keep up the mapping!

Exisitng editors for text data DjVu files are quite limited, like for example DjVuSmooth. So I've implemented a new editor in JavaScript, that allows editing both the strucutre of the text (paragraphs, lines, words,...) and the coordinates of the text boxes by simply dragging with the mouse, features like create, delete, merge are also available.
