Detailed Description

Read vector file formats using GDAL.

vtkGDALVectorReader is a source object that reads vector files and uses GDAL as the underlying library for the task. GDAL is required for this reader. The output of the reader is a vtkMultiBlockDataSet

Member Function Documentation

static vtkGDALVectorReader* vtkGDALVectorReader::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkMultiBlockDataSetAlgorithm.

virtual void vtkGDALVectorReader::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkMultiBlockDataSetAlgorithm.

static int vtkGDALVectorReader::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkMultiBlockDataSetAlgorithm.

virtual int vtkGDALVectorReader::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkMultiBlockDataSetAlgorithm.

static vtkGDALVectorReader* vtkGDALVectorReader::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkMultiBlockDataSetAlgorithm.

virtual vtkObjectBase* vtkGDALVectorReader::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkMultiBlockDataSetAlgorithm.

vtkGDALVectorReader* vtkGDALVectorReader::NewInstance ( ) const

Reimplemented from vtkMultiBlockDataSetAlgorithm.

virtual void vtkGDALVectorReader::SetFileName ( const char * ) [virtual]

virtual char* vtkGDALVectorReader::GetFileName ( ) [virtual]

int vtkGDALVectorReader::GetNumberOfLayers ( )

Return number of layers.

int vtkGDALVectorReader::GetLayerType ( int layerIndex = 0 )

Given a index return layer type (eg point, line, polygon).

int vtkGDALVectorReader::GetFeatureCount ( int layerIndex = 0 )

Given a layer index return number of features (shapes).

int vtkGDALVectorReader::GetActiveLayerType ( )

Return the active layer type (eg point, line, polygon).

int vtkGDALVectorReader::GetActiveLayerFeatureCount ( )

Return the number of features in the active layer (shapes).

virtual void vtkGDALVectorReader::SetActiveLayer ( int ) [virtual]

Set and Get the active layer

virtual int vtkGDALVectorReader::GetActiveLayer ( ) [virtual]

Set and Get the active layer

virtual void vtkGDALVectorReader::SetAppendFeatures ( int ) [virtual]

Set and Get whether features are appended to a single vtkPolyData. Turning the option on is useful when a shapefile has a number of features which could otherwise lead to a huge multiblock structure.

virtual int vtkGDALVectorReader::GetAppendFeatures ( ) [virtual]

Set and Get whether features are appended to a single vtkPolyData. Turning the option on is useful when a shapefile has a number of features which could otherwise lead to a huge multiblock structure.

virtual void vtkGDALVectorReader::AppendFeaturesOn ( ) [virtual]

Set and Get whether features are appended to a single vtkPolyData. Turning the option on is useful when a shapefile has a number of features which could otherwise lead to a huge multiblock structure.

virtual void vtkGDALVectorReader::AppendFeaturesOff ( ) [virtual]

Set and Get whether features are appended to a single vtkPolyData. Turning the option on is useful when a shapefile has a number of features which could otherwise lead to a huge multiblock structure.

std::map<int, std::string> vtkGDALVectorReader::GetLayersProjection ( )

Return projection string belong to each layer.

const char* vtkGDALVectorReader::GetLayerProjection ( int layerIndex )

Return projection string belong to a layer.
