New icons may be requested via GitHub issues. Please search through existing issues first to see if your request is not already covered. Please also limit issues to a single icon or a small number of very closely related icons.
Osmic uses "Fork & Pull" for contributions (see https://help.github.com/articles/using-pull-requests). Adjustments and improvements to existing icons are very welcome. New icons are only considered if they fit to the general appearance of Osmic and are of high quality. There might be modifications to proposed icons before they are added.
Please limit new icon pull requests to one icon each unless they are very closely related in concept and design.
By contributing you agree to release your work under CC0 (or Public Domain), see the license for details. If submitting new icons or substantial modifications you confirm that this is your own work and it is free of the rights of others.
It is recommended to use Inkscape (https://inkscape.org) for creating or modifying SVG files. Please do not submit files in Inkscape's own SVG-like format as it contains a lot of clutter. Instead use File > Save As ... and select "Plain SVG".
Icon standard canvas size is 14x14px without any padding i.e. the icon can use all of the available space. The icon file name should use dashes for whitespace and append the canvas size (e.g. waste-basket-14.svg).
All icon content has the colour black (#000000) and consists of a single path (parts merged together). The path's ID is similar to the file name without the canvas size part (e.g. waste-basket-14.svg has id waste-basket).
In the background all icons have a invisible rectangle spanning the whole canvas to avoid up-/downscaling of the shape alone when using marker-width or marker-height in CartoCSS. The style of this rectangle has set visibility:hidden and uses the id canvas. See one of the icons for an example how this looks.
The shapes should be aligned to the pixel grid as much as possible to avoid a blurry representation. The pixel grid can be brought up within Inkscape by pressing # or by selecting View > Grid. When enabled nodes automatically snap to the grid.
