[mkgmap-dev] straight lines are deformed

Mon May 6 19:04:15 BST 2013

Hi Minko,

The zig zag effect looks like the remove-short-arcs function: Some points
are moved.
I don't see why this would not also happen in r2564.
Please check:
1) Are you able to reproduce this problem with exactly the same input files
and parms?
2) Did you apply the overlayed_lines_v1.patch to one of the programs?
