SpatialTransform

globalmapper.SpatialTransform(GM_SpatialTransforms_t16 aTransform, GM_LayerHandle_t32 aLayer, GM_SpatialOps_Params_t aParams, GM_FeatureGrouping_t8 aGrouping, str aStr) → GM_Error_t32

General Transform function. Can be used to perform any of the one-layer spatial transform functions available in Global Mapper, using aTransform to define which transform function.

Currently, the available transform functions and their parameter values are:

• SpatialMBR - GM_SpatialTransform_MBR

• SpatialCenter - GM_SpatialTransform_Center

• SpatialConvexHull - GM_SpatialTransform_ConvexHull

• SpatialConcaveHull - GM_SpatialTransform_ConcaveHull

• SpatialBuffer - GM_SpatialTransform_Buffer

Parameters:

• aTransform (GM_SpatialTransforms_t16) – Transform type

• aLayer (GM_LayerHandle_t32) – Input layer

• aParams (GM_SpatialOps_Params_t) – Parameters

• aGrouping (GM_FeatureGrouping_t8) – Grouping type

• aStr (str) – The attribute list string; may be an empty string

Returns:

Error Code

Return type:

GM_Error_t32
