I don't know if you understand me correct. The resulting map should be blue area in attached picture. I can cut OSM-data with osmconvert to this polygon. If splitter generates an areas.list for the resulting osm-file, splitter generates a areas.list for red and blue parts. It would be nice, if I can tell splitter only generate tiles for blue area. okay, I understand what you mean. Are you sure that we don't need polygons that do not form rectangles? If we can limit it to a list of rectangles, the change would be quite small. I don't know. AFAIK splitter and mkgmap only supports rectangular tiles till now. So I think only rectangular tiles would be ok. If given polygon isn't rectangular splitter could generate a warning, that only rectangular polygons are allowed.
I think it would be good to support the osmosis polygon-file format, but probably there is no need to use the precise values. The current splitter just counts the nodes that fall into grid elements. As a first approach I would simply set those grid elements to zero that do not intersect with the polygon. I think this will directly lead to the result that you need.
