Hi,
I was wondering if there is any current capability to control the styling
of arrows that appears on ways in JOSM. Specifically, I'm interested in
capability to control the size of the arrows, their color, and how often
they appear.
If so, could you share some syntax as well of how to do this ?
I've searched through the mail archives and didn't find anything.
You can draw the arrows with repeated images along the line
(repeat-image, since v. 5801). Instead of including a png file, you can
also include svg or embed it inline:
way[oneway=yes]::arrows {
repeat-image: "data:image/svg+xml,<svg><path d='M 0 0 L 10 5 L 0 10
z' fill='white' stroke='blue'/></svg>";
repeat-image-spacing: 30;
major-z-index: 3.1;
}
One problem is to get rid of the default arrows, currently there is no
direct way to turn them off in your style sheet. As a workaround, you
could hide the line style on the default layer (opacity 0.0) and draw
another line on a different layer. I admit this is not very practical,
but at least it's possible.
way[oneway=yes] {
opacity: 0.0;
}
way[oneway=yes]::snd {
width: 3;
color: blue;
}
The more specific the questions get for JOSM, the more you might
consider to ask on the JOSM mailing list, or open a ticket on
josm.openstreetmap.de directly.
