globalmapper.RepositionLayer

globalmapper.RepositionLayer(GM_LayerHandle_t32 aLayer, GM_GroundControlPoint_t aGCPList, uint32 aNumGCPs, GM_Projection_t aProj) → GM_Error_t32[source]

Repositions/reprojects the given layer.

The layer will be positioned according to the ground control point (GCP) list provided. The ground coordinates in the GCP list must be given in the projection specified by aProj. If you just want to change the native projection of the layer, provide None for the aGCPList parameter and provide the new native projection with the aProj parameter.

Parameters:

  • aLayer (GM_LayerHandle_t32) – the layer you want to reposition

  • aGCPList (GM_GroundControlPoint_t) – the list of ground control points to use to reposition the layer

  • aNumGCPs (uint32) – the size of aGCPList

  • aProj (GM_Projection_t) – the projection to use for the layer and GCPs

Returns:

Return type:

GM_Error_t32
