RE: VB: [OpenMap Users] color on map gets wicked

Hi Don,
If I have a lake polygon inside a country border polygon the lake polygon is filled first with the country color and then with the lake color, resulting in a mix of the two colors in the lake.

Hi David,

Are the features that are being colored twice painted with the same
color, or with different colors? I'm wondering if your data has
polygons with holes, and OpenMap probably won't handle them correctly.
