SetAreaFeaturePointListEx

globalmapper.SetAreaFeaturePointListEx(GM_LayerHandle_t32 aLayer, uint32 aAreaIndex, uint32 aHoleIndex, [GM_Point_t] aPointList, bool aPosInLayerCoords, float_array aElevList) → GM_Error_t32[source]

Sets the list of point locations to use for the given area feature. The positions can either be specified in the native projection system of the layer (aPosInLayerCoords is TRUE) or in the current projection as returned by GetProjection (aPosInLayerCoords is FALSE). The positions can also optionally have individual elevations via aElevList.

The aHoleIndex parameter allows you to set the position list for holes within an area as well as the main parent area. To set the position list for the main parent area, use a value of 0 for aHoleIndex. To set the position of one of the holes in the area, set aHoleIndex to the 1-based index of the hole in the area.

Parameters:

  • aLayer (GM_LayerHandle_t32) – Layer the area is in

  • aAreaIndex (uint32) – Index of area in layer

  • aHoleIndex (uint32) – Index of hole to apply locations to (0 for main parent area, 1 for first hole, etc.)

  • aPointList ([GM_Point_t]) – New list of points for area

  • aPosInLayerCoords (bool) – Are the position in the layer coordinate system or the current coordinate system?

  • aElevList (float_array) – Per-vertex elevations for area feature, or gm.NULL for none

Returns:
