[mkgmap-dev] Problem Displaying Polygons with Extended Type codes

Tue Jul 5 11:09:05 BST 2011

Charlie,

Thank you for providing the download links.

They were very useful. After many rebuilds and recombination's of the 
TYP file split from your gmapsupp.img with my compiles I found the 
problem. It was a 'beginners' mistake on my part. I had been saving my 
TYP files with the 'OLD' Header format which meant that the drawing 
orders of the extended-code polygon types were somehow very messed up.

No problem therefore with display of extended polygon codes on the 
Garmin GPSMAP62s.

Thanks for the help.

Bill.
