Hello Again,
I think I found where my extended-type lines disappear. They are simply not
taken into account when estimating subdivision size, i.e:
MapArea.java, lines 389-394
private void addSize(MapElement p, int[] sizes, int kind) {
-> if(p.hasExtendedType()) {
-> // not applicable for elements with extended types
-> return;
-> }
So subdivisions end up too big (and are not drawn correctly) if there are a
lot of extended-type elements. I commented out above lines in MapArea.java,
rebuilt mkgmap (r1274) and seems to work, i.e. extended lines are no longer
dropped in i.e. MapSource.
I am not sure if I am breaking anything else, so please, somebody who
understands the code and implications more, please check this.
Thanks.
Ivan.
