Röntgen is a set of monochrome 14 × 14 px pixel-aligned icons. All icons are under the CC BY 4.0 license. So, do whatever you want, but please give the appropriate credit.
Röntgen was created for the Map Machine project to represent different map features from the OpenStreetMap database. However, it can be easily used for any map project or even for non-map-related projects. Also, some icons can be used as emoji symbols. Version 0.1 of Röntgen is used in iD editor for OpenStreetMap.
All icons can be found in the icons directory, where they are stored
as optimized SVG files. Every icon file is less than 3 KB in size.
All icons tend to support a common design style, which is heavily inspired by Maki, Osmic, and Temaki.
Feel free to request new icons via issues on GitHub.
- Icons must be monochrome, meaning they cannot have parts in different colors. This ensures they can be recolored without losing their meaning.
- Icons must be 14 × 14 px in size (equivalent to 16 × 16 px with one pixel padding).
- Icon parts should be pixel-aligned for better rendering, when it is possible.
- Lines should have rounded caps if it doesn't affect shape recognition.
The icons directory contains generated and optimized SVG icons. They are
generated from sketch SVG files in the data directory by Python
scripts. It is hugely simplifies the process of creating new icons.
To regenerate icons, run
roentgen iconsRöntgen was created for the Map Machine, a rendering engine for OpenStreetMap data and it's primary purpose is to represent tags of objects from the OpenStreetMap database.
The data/tags.json file contains a possible mapping from OpenStreetMap tags
to Röntgen icons.
