[mkgmap-dev] [mkgmap-svn] Commit r4811: fix java.lang.AssertionError while building index from unicode tiles

Thu Nov 18 16:44:33 GMT 2021

Hi Gerd

With the patched version that ignores shields, I've been using them to
look at various effect on sorting and gmapi > baseCamp/MapInstall >
gmapsupp on device and back to MdrCheck

at end of lines:
mkgmap:city=Wherwell & highway=* & name=*
  {set mkgmap:city='${mkgmap:city|highway-symbol:"box"}'}
mkgmap:city=Upham & highway=* & name=* {
   set mkgmap:city=Wherwell;
   set mkgmap:city='${mkgmap:city|highway-symbol:"hbox"}'
   }

at end of points:
name=Upham & place=* {
   set mkgmap:city=Wherwell;
   set mkgmap:city='${mkgmap:city|highway-symbol:"oval"}';
   set mkgmap:label:1='${mkgmap:city}'
   }

shields are: 0x0001 .. 0x0006 for all but cp0

I'm not sure if the boundaries are 256 / 65536 because of extra flags.
