When using the arrow item in the map composer, the line of the arrow goes beyond the arrowhead (see attached screenshot).
It worked well with QGIS 2.x.
As I don't want the arrowhead to be round, I use these parameters:
  • Arrow outline width: 0 mm
  • Arrow head width: 3 mm

  • Regression? changed from No to Yes
  • Priority changed from Normal to High

#2 Updated by Marco Hugentobler 11 months ago

QGIS 2.18 was moving the end arrow by half the arrow width. It seems to me we can just use this solution for QGIS3 too. https://github.com/qgis/QGIS/pull/9129 provides a pull request.

Fixed in master branch (https://github.com/qgis/QGIS/pull/9129). Change will be backported to 3.4 branch
