To annotate a picture, I have many arrows to add. For visibility I want to add a light border around them.
I want to draw an arrow with this kind of appearance:
I tried to convert my line in path, but the trouble is that you cannot modify the arrow as a line after this transformation. In addition, each head (marker) has to be manually corrected at the junction between the line and the marker.
I also tried the filter Morphology>Contour... the best result I could achieved is this one (not selecting 'Live Preview' which end in a black rectangle):
I am not happy because I did not manage to select the color and thickness of the contour.
And I have got strange behavior for horizontal line (unwanted cropping, an disparition of the line, when completly horizontal)
What would you recommend to draw kind of kind of arrow ? Since I am not very experimented with inkscape, I think I am missing something obvious.
I am using inkscape 0.92.3.
