Resumen
Create a new geometry object from a well-known binary (WKB) string stored in a bytearray.
Sintaxis
FromWKB (byte_array)
| Parámetro | Explicación | Tipo de datos |
byte_array | A WKB string stored in a Python bytearray. | Bytearray |
| Tipo de datos | Explicación |
| Geometry |
FromWKB returns a geometry object (PointGeometry, Multipoint, Polyline, or Polygon) based on the input bytearray. |

This example illustrates the use of converting a WKB to a geometry object.
import arcpy
fc = "c:/base/gdb.gdb/counties"
rows = arcpy.da.SearchCursor(fc, ['SHAPE@'])
studyarea = rows.next()[0]
# Create geometry to WKB
polyWKB = studyarea.WKB
# Convert WKB back to a geometry
polyGeom = arcpy.FromWKB(polyWKB)
