Title: track/item change contour depending on zoomlevel
Post by: balloni55 on August 25, 2016, 21:14:56
zooming out till ZL 13 all work fine
on ZL 12 purple outline change contour
on ZL 11 red outline  change contour

That's from randomly simplification algorithm
try map_items_track_simplification_till_zoom=8

Thanks gynta 8)
for me the discription of this parameter is misleading
# same as points_simplification. (default: 22)
map_items_track_simplification_till_zoom=22

in "points_simplification" icon is reduced to dot
and in "track_simplification" count of trackpoints of track are reduced ???
additional: default value is set to 22, so all tracks are reduced on ZL<22, who know this??

Maybe more then two people? Hmm :). Anyway yes, almost all tracks are simplified in zoom levels below 22. Simplification is increasing with lower zoom levels and in lowest zoom levels (like when you see whole world), only every 500th point of track is drawn. Enjoy blazingly fast maps for huge number of tracks at low zoom levels ;)

well, think about word "simplification" like about "methods, how to make rendering faster".

think Wolfgang talk about description "same as points..."
because points are shrinking to small green points.
but tracks lose some trackpoints
So it's not the same
It's more a "german be precisely" problem  ;D
