[Geoserver-users] startAngle and EndAngle values incorrect

[yaras_phoenix via Geoserver-users]

Hello!

Geoserver 2.15.2

I need to create a style with arrows on the start and end points of the line
with orientation of the corresponding segment of the line. I took a TTF
wingdings 3 symbol and used startPoint, endPoint, startAngle and endAngle
functions to render points and make rotation. Here's my style:

I expected the arrows to be oriented on the line segments but here's what
I've got:
<http://osgeo-org.1560.x6.nabble.com/file/t385725/Capture.png> 

I wondered if turning the arrows 90 degrees CW and CCW would solve the
problem...but no:

Different behaviour on different objects. 

What am I doing wrong?
