Methods

__init__(filename: char, type: int = -1)[исходный код]

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[исходный код]

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

addPoint(point: pointObj) int[исходный код]

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

get(i: int, shape: shapeObj) int[исходный код]

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

getDBF() DBFInfo[исходный код]

Returns a DBFInfo object containing information on the associated DBF

getExtent(i: int, rect: rectObj) void[исходный код]

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

getPoint(i: int, point: pointObj) int[исходный код]

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

getShape(i: int) shapeObj[исходный код]

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

getTransformed(map: mapObj, i: int, shape: shapeObj) int[исходный код]

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
