Is the angle given the mathematical angle Ie with 0 running along the x-axis and 90 runing North on the y-axis? If so you can correct for this by subtracting it from 450 then if the angle is greater than 360 you can subtract 360 from it.
Eg: if the angle is 30 deg from the horizontal the final angle is (450 -30)-360 = 60 -----Original Message----- From: yaras_phoenix via Geoserver-users [mailto:geoserver-users@lists.sourceforge.net] Sent: Wednesday, 18 December 2019 2:21 AM To: geoserver-users@lists.sourceforge.net Subject: [Geoserver-users] startAngle and EndAngle values incorrect 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.
