Leaflet-Semicircle.
Adds semicircle functionality to L.Circle. Angles are defined like compass courses: 0 = north, 90 = east, etc. If the script is not included, Leaflet will fall back drawing full circles.
Updated for use with leaflet 1.0.0-rc.1.
Provided methods
L.Circle.setStartAngle(angle) |
Set the start angle of the circle to angle and redraw. |
L.Circle.setStopAngle(angle) |
Set the stop angle of the circle to angle and redraw. |
L.Circle.setDirection(direction, size) |
Set the startAngle to direction - (0.5 * size) and the stopAngle to direction + (0.5 * size) and redraw. |
Usage:
The plugin provides two ways to only display a part of the circle:
- Use the
options
map and setstartAngle
andstopAngle
. - Use
setDirection(direction, size)
to display a semicircle ofsize
degrees atdirection
.
Example:
Useing options.startAngle
and options.stopAngle
:
L.circle([51.5, -0.09], {
radius: 500,
startAngle: 45,
stopAngle: 135
}).addTo(map);
Draw the same semicircle using setDirection(direction, size)
:
L.circle([51.5, -0.09], {radius: 500})
.setDirection(90, 90)
.addTo(map);
