Changes between Version 14 and Version 15 of DevelopersGuide/DefaultPresets

v14	v15
22	22	* svg icons are automatically cleaned up to reduce file size in the JOSM build. So there is no need to do this step manually before uploading svg files to svn. See comment:35:ticket:10479 and comment:10:ticket:10877
23	23	* The icon should identifiable at a size of 16 pixels. This is the size the icons are displayed in the [[Help/MapView\|Map View]].
24		* The license needs to be compatible with GPL3 (like PD or CC0)
	24	* The license needs to be compatible with GPL3 (like PD or CC0). A good source for Icons is [http://openclipart.org openclipart.org] (all icons there are PD).
25	25	* If the tag applies to nodes, the icon in the MapView and the icon of the preset should be the same if possible. (It is not possible when different features use the same preset, e.g. crossing=island and crossing=traffic_signals have different icons, but are handled in only one preset "Pedestrian Crossing".)
26	26	* Icons with transparent background must not be only black or only white. Otherwise if one uses a black or white background (no aerial imagery as background) in the Map View black or white icons would be invisible. Workaround: if you want to use a black icon add a square white background to the icon instead of a transparent background. This doesn't look pretty but is better than an invisible icon. Example: [[Image(BlackWhiteIcon.png)]]
