Value | Meaning |
---|---|
VECTOR_POLYGON_POINT | Draw only the edge points on polygons and lines. |
VECTOR_POLYGON_LINE | Draw as a wire-frame. |
VECTOR_POLYGON_FILL | Draw solid polygons. |
VECTOR_POLYGON_FILL_RASTER_ALWAYS | Draw solid polygons and always draw raster objects. |
This function is not supported in the GDI engine.
