Hi all, I think the meaning of the --transparent option is a bit unclear . It tells mkgmap to set a flag in the TRE header and it tells mkgmap NOT to add a background polygon (0x4B) covering the tile. I wonder if it should also mean that mkgmap should remove (filter) all 0x4b polygons added by the style or read from polish (*.mp) sources (and maybe warn about this when it does so). The current implementation doesn't do that. The implementation for the overview map always adds a 0x4b polygon in the overview map, no matter what the --transparent option says. The TRE header in the overview map is written with default values (not transparent, draw priority 25). I assume that is okay since I don't think that one can have multiple overview maps.
