[mkgmap-dev] Bad tile around East London / Greenwich

Sat Aug 7 16:17:47 BST 2021

Hi Jan

It wasn't so much the type number as the size of a poi bitmap.

In the 'olden' days Mapsource would allow pois with lengths and width 
equalling zero. This would render them transparent, useful for names of 
places.

However, Basecamp would not accept such pois and I think has a problem 
displaying some pois with length and width  set to 1.

I'm glad it wasn't the typ file.
