mapscript.shapefileObj

class mapscript.shapefileObj(filename: char, type: int = -1)

An object representing a Shapefile. There is no write access to this object using MapScript.

Attributes

bounds	rectObj immutable Extent of shapes
numshapes	int immutable Number of shapes
thisown	The membership flag
type	int immutable Shapefile type - see mapshape.h for values of type

Methods

__init__(filename: char, type: int = -1)

Create a new instance. Omit the type argument or use a value of -1 to open an existing shapefile.

Type should be one of MS_SHAPEFILE_POINT, MS_SHAPEFILE_ARC, MS_SHAPEFILE_POLYGON or MS_SHAPEFILE_MULTIPOINT

add(shape: shapeObj) → int

Appends a shape to the open shapefile. Returns MS_SUCCESS or MS_FAILURE

addPoint(point: pointObj) → int

Appends a point to the open shapefile. Returns MS_SUCCESS or MS_FAILURE

get(i: int, shape: shapeObj) → int

Get the shapefile feature from index i and store it in shape. Returns MS_SUCCESS or MS_FAILURE

getDBF() → DBFInfo

Returns a DBFInfo object containing information on the associated DBF

getExtent(i: int, rect: rectObj) → void

Retrieve a shape's bounding box by index and stores it in rect.

getPoint(i: int, point: pointObj) → int

Returns the point feature at index i and store it in pointObj.

getShape(i: int) → shapeObj

Returns the shapefile feature at index i. More efficient than get.

getTransformed(map: mapObj, i: int, shape: shapeObj) → int

Returns the feature at index i, simplify it, and store it in shape. Uses the map extent and cellsize for simplification. Returns MS_SUCCESS or MS_FAILURE
