This is a way +to guarantee that we use consistent colors across the +diagrams used in our documentation. + +See <https://inkscape-manuals.readthedocs.io/en/latest/palette.html> +for details about working with color palettes in Inkscape. + +### Template diagram + +The `template/` directory contains a `template.svg` file +to make it easier to create diagrams. +In particular, you can use it to copy standard text, shapes, +arrows and clipart to the new SVG document. + +### Fonts + +The recommended font for description text and labels is `Nimbus Roman`, size 10. +Labels are in bold. + +`template.svg` contains ready-to-copy labels. + +### Text boxes + +Text boxes are rectangle boxes, with rounded corners, and contain centered text +or labels. Their stroke color is slightly darker than their fill color. + +See `template.svg` for example boxes with different colors, which are ready +to be reused. + +### Clipart + +Only [Public Domain](https://en.wikipedia.org/wiki/Public_domain) +files are accepted for clipart. [Openclipart](https://openclipart.org) +is the best known and recommended source of such clipart. + +It is also required to state the source of each new clipart in the commit log, +to make it possible to check its origin. + +For the sake of consistency across diagrams, we recommend +to use existing cliparts, whenever possible. + +If cliparts in `template.svg` do not satisfy your requirements, you can +add to said file new cliparts, from e.g. Openclipart. Newly added +cliparts shall stay consistent in style and color with existing ones. |
