Detailed Description

Convert pixels to real-world values.

This filter uses the information in the DICOM meta data to convert the pixel values to real-world values with known units. It uses the DICOM RealWorldValueMapping attributes, if present, otherwise it uses the RescaleSlope and RescaleIntercept. If no mapping information is present, then the pixels are simply converted to floating-point.

Warning: If this filter is used, then AutoRescaleOff() should be set on the reader to ensure that the reader does not rescale the data.

Member Function Documentation

◆ IsA()

virtual vtkTypeBool vtkDICOMApplyRescale::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 vtkDICOMAlgorithm.

◆ RequestData()

int vtkDICOMApplyRescale::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)

protectedvirtual

This is called in response to a REQUEST_DATA request from the executive. Subclasses should override either this method or the ExecuteDataWithInformation method in order to generate data for their outputs. For images, the output arrays will already be allocated, so all that is necessary is to fill in the voxel values.

Reimplemented from vtkDICOMAlgorithm.

◆ RequestInformation()

int vtkDICOMApplyRescale::RequestInformation	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)

protectedvirtual

Subclasses can reimplement this method to collect information from their inputs and set information for their outputs.

Reimplemented from vtkDICOMAlgorithm.

◆ ThreadedRequestData()

void vtkDICOMApplyRescale::ThreadedRequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector,
		vtkImageData ***	inData,
		vtkImageData **	outData,
		int	extent[6],
		int	threadId
	)

protectedvirtual

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method.

Reimplemented from vtkDICOMAlgorithm.

The documentation for this class was generated from the following file:

vtkDICOMApplyRescale.h
