Function Documentation

int ComputeHomerange (  DPOINT2D **  Points, INT32  NumPoints, DPOLYGON **  Dpolys, INT32 *  NumDpolys, POLYFITPARM *  pfparm )

Compute region from set of points using polygon fitting.

int MregionFromBasin (  int  rhandle, int  vhandle, int  NumElemTypes, RGNELEMLIST *  ElemList, REGION2D &  region )

Create a region from basin.

int MregionFromBufferZone (  int  vhandle, int  NumElemTypes, RGNELEMLIST *  ElemList, DOUBLE  PointDistance, DOUBLE  LineDistance, DOUBLE  PolyDistance, int  Unit, bool  side, REGION2D &  region )

Create a region from buffer zone.

int MregionFromCluster (  int  vhandle, RGNELEMLIST *  ElemList, int  NumElemTypes, CLASSIFY_PARM *  clparm, REGION2D &  region )

Create a region from a cluster. Parameters: NumElemTypes  Number of element types

int MregionFromPolygonFit (  int  vhandle, RGNELEMLIST *  bitarray, int  NumPoints, POLYFITPARM *  pfparm, REGION2D &  region )

Generate a region from a polygon fit of selected points. Returns: 1 if one or more regions generated, 0 if no regions generated, error code if < 0. Polygon fit methods: RGNPFIT_MINPOLY RGNPFIT_HARMON RGNPFIT_FOURIER RGNPFIT_TESSEL Parameters: vhandle  Handle to open RVC vector object bitarray  Selected points to generate polygon around NumPoints  Number of points that the array covers pfparm  Polygon fit parameter structure

int MregionFromTextureGrowth (  int  rhandle, int  vhandle, int  NumElemTypes, RGNELEMLIST *  ElemList, DOUBLE  numSD, INT32  Around, REGION2D &  region, UINT32  ProcessType )

Create a region by raster texture growing.

int MregionFromVoronoi (  int  vhandle, RGNELEMLIST *  ElemList, int  NumElemTypes, DOUBLE  ExtFactor, REGION2D &  region )

Create a region from Voronoi diagram. Parameters: NumElemTypes  Number of element types region  Region returned

void MregionInitPolygonFit (  POLYFITPARM *  pfparm, UINT32  method )

Initialize parameters to defaults for polygon fitting. See MregionFromPolygonFit() for details on POLYFITPARM and methods.
