Who knows (in precise detail) how markers are rendered ? For some reason, the history of markers rendered determines the render order of the markers. Have a look at bug478157.svg in our testsuite. Open the XML editor, and select the 2nd path from the left. Change the path from "m 30,140 -0.5,-100 0,0" to "m 30,140 0,0 -0.5,-100 0,0" and then back. The render order of markers has changed.

Thanks for any answer, Johan

Hi all,

See https://bugs.edge.launchpad.net/inkscape/+bug/478157. Currently, endmarkers are drawn beneath midmarkers,

although the code

this has to

do with the 'key' that is passed to sp_marker_show_instance? (determines the layer?)

Have a look at sp_shape_update_marker_view in sp-shape.cpp.

I'm afraid that code is in a different layer altogether. This deals with SPObjects, but what you need is ArenaItems. As I recollect without looking at the code, the path/shape arena item also stores markers and eventually renders them. Look into libnr/.
