BufferPolygon
Syntax
bool BufferPolygon(ref MapWinGIS.Shape polygon, System.Double distance, MapWinGeoProc.Enumerations.Buffer_HoleTreatment holeTreatment, MapWinGeoProc.Enumerations.Buffer_CapStyle capStyle, ref MapWinGIS.Shape resultShp)
Summary
Creates a buffer around (or inside of) the input polygon at the distance specified.
Parameters
| polygon | The polygon shape to be buffered. |
| distance | The distance from the polygon's border that the buffer should be created. Positive or Negative values are allowed. |
| holeTreatment | For multiPart polygons with holes, specifies what should be done with holes. 0 = ignore (no holes will be included in result buffer), 1 = opposite (if distance is positive, hole will shrink), 2 = same (if distance is positive, hole will grow), 3 = keep original (the hole will not be buffered but will still exist inside of the buffer shape). |
| capStyle | Edge treatment. 0 = pointed, 1 = rounded. |
| resultShp | The resulting buffer shape. |
Returns
False if an error was encountered, true otherwise.
