overridevirtual

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 vtkObject.

◆ SetNoDataValue()

virtual void vtkGDALRasterConverter::SetNoDataValue ( double  )
virtual

No-data value for pixels in the source image Default is NaN (not used).

◆ GetNoDataValue()

virtual double vtkGDALRasterConverter::GetNoDataValue ( )
virtual

No-data value for pixels in the source image Default is NaN (not used).

GDALDataset * vtkGDALRasterConverter::CreateGDALDataset ( int  xDim,
int  yDim,
int  vtkDataType,
int  numberOfBands

Copies color interpretation and color tables.

◆ CreateVTKUniformGrid()

vtkUniformGrid * vtkGDALRasterConverter::CreateVTKUniformGrid ( GDALDataset *  input)

Create vtkUniformGrid to match GDALDataset.

The calling code must call the Delete() method to release the returned instance.

◆ SetGDALProjection()

void vtkGDALRasterConverter::SetGDALProjection ( GDALDataset *  dataset,
const char *  projectionString 
)

Set projection on GDAL dataset, using any projection string recognized by GDAL.

◆ SetGDALGeoTransform()

void vtkGDALRasterConverter::SetGDALGeoTransform ( GDALDataset *  dataset,
double  origin[2],
double  spacing[2],
int  flipAxis[2] 
)

Set geo-transform on GDAL dataset.

◆ CopyNoDataValues()

void vtkGDALRasterConverter::CopyNoDataValues ( GDALDataset *  src,
GDALDataset *  dest

Copies NoDataValue info from 1st to 2nd dataset.

◆ WriteTifFile()

void vtkGDALRasterConverter::WriteTifFile ( GDALDataset *  dataset,
VTK_FILEPATH const char *  filename 
)

Write GDALDataset to tiff file.

◆ FindDataRange()

bool vtkGDALRasterConverter::FindDataRange ( GDALDataset *  dataset,
int  bandId,
double *  minValue,
double *  maxValue 
)

Traverse values in specified band to find min/max.

Note that the bandId starts at 1, not zero. Returns boolean indicating success.

◆ CopyToGDAL()

bool vtkGDALRasterConverter::CopyToGDAL ( vtkImageData input,
GDALDataset *  output,
int  flipAxis[3] 
)
protected

Copies vtkImageData contents to GDALDataset GDALDataset must be initialized to same dimensions as vtk image.
