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

This filter uses the ActiveLayer member to only load entries from the specified layer (when ActiveLayer >= 0).

static

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 *  type )

static

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.

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. If ActiveLayer is less than 0 (the default is -1), then all layers are read. Otherwise, only the specified layer is read.

virtual int vtkGDALVectorReader::GetActiveLayer ( )

virtual

Set and Get the active layer. If ActiveLayer is less than 0 (the default is -1), then all layers are read. Otherwise, only the specified layer is read.

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.

virtual void vtkGDALVectorReader::SetAddFeatureIds ( int  )

virtual

Set/get whether feature IDs should be generated. Some GDAL primitives (e.g., a polygon with a hole in its interior) are represented by multiple VTK cells. If you wish to identify the primitive responsible for a VTK cell, turn this on. It is off by default for backwards compatibility. The array of feature IDs will be the active cell-data pedigree IDs.

virtual int vtkGDALVectorReader::GetAddFeatureIds ( )

virtual

Set/get whether feature IDs should be generated. Some GDAL primitives (e.g., a polygon with a hole in its interior) are represented by multiple VTK cells. If you wish to identify the primitive responsible for a VTK cell, turn this on. It is off by default for backwards compatibility. The array of feature IDs will be the active cell-data pedigree IDs.

virtual void vtkGDALVectorReader::AddFeatureIdsOn ( )

virtual

Set/get whether feature IDs should be generated. Some GDAL primitives (e.g., a polygon with a hole in its interior) are represented by multiple VTK cells. If you wish to identify the primitive responsible for a VTK cell, turn this on. It is off by default for backwards compatibility. The array of feature IDs will be the active cell-data pedigree IDs.

virtual void vtkGDALVectorReader::AddFeatureIdsOff ( )

virtual

Set/get whether feature IDs should be generated. Some GDAL primitives (e.g., a polygon with a hole in its interior) are represented by multiple VTK cells. If you wish to identify the primitive responsible for a VTK cell, turn this on. It is off by default for backwards compatibility. The array of feature IDs will be the active cell-data pedigree IDs.
