[mkgmap-dev] straight lines are deformed

Mon May 6 15:03:28 BST 2013

Hi Minko,

I am surprised about this effect. I think the main difference betwen
merge-lines in r2564 and r2590
is that r2560 used it only for res < 22, but r2590 uses it also for res <=
24. So, you should not see any
difference for res < 22.
Anyway, the zig-zag is not ok, I'll try to find out what goes wrong.
