Constructor & Destructor Documentation

◆ DcmSegmentation()

template<typename ImagePixel >

DcmSegmentation::DcmSegmentation ( OFin_place_type_t(ImagePixel) )

protected

Protected default constructor.

Library users should the factory create..() method in order to create an object from scratch

Member Function Documentation

◆ addForAllFrames()

virtual OFCondition DcmSegmentation::addForAllFrames ( const FGBase & group )

virtual

Add a functional group for all frames.

Parameters

group The group to be added as shared functional group. The

Returns: EC_Normal if adding was successful, error otherwise

◆ addFrame() [1/2]

template<typename T >

OFCondition DcmSegmentation::addFrame ( T * pixData )

protected

Add frame to segmentation object.

Parameters

pixData Pixel data to be added. Length must be rows*columns bytes. Pixel data is copied so it must be freed by the caller.

Returns: EC_Normal if adding was successful, error otherwise

References DCM_SEG_MAX_FRAMES, DcmIODImage< IODImagePixelModule< Uint16 >, IODImagePixelModule< Uint8 > >::getImagePixel(), m_Frames, m_SegmentationType, SG_EC_MaxFramesReached, OFVector< T >::size(), and DcmSegTypes::ST_BINARY.

◆ addFrame() [2/2]

template<typename T >

OFCondition DcmSegmentation::addFrame	(	T *	pixData,
		const Uint16	segmentNumber,
		const OFVector< FGBase * > &	perFrameInformation
	)

Add frame to segmentation object.

Parameters

pixData	Pixel data to be added. Length must be rows*columns bytes. For binary segmentations (bit depth i.e. Bits Allocated/Stored=1), each byte equal to 0 will be interpreted as "not set", while every other value is interpreted as "set". For fractional segmentations the full byte is copied as is. For labelmap segmentations, the value of each byte is interpreted as the segment number. In that case the segmentNumber parameters is ignored.
segmentNumber	The logical segment number (>=1) this frame refers to. The segment identified by the segmentNumber must already exist. For labelmap segmentations, this parameter is ignored.
perFrameInformation	The functional groups that identify this frame (i.e. which are planned to be not common for all other frames). The functional groups are copied, so ownership of each group stays with the caller no matter what the method returns.

Returns: EC_Normal if adding was successful, error otherwise

◆ addSegment()

virtual OFCondition DcmSegmentation::addSegment	(	DcmSegment *	seg,
		Uint16 &	segmentNumber
	)

virtual

Add segment to segmentation object.

Parameters

seg The segment that should be added

segmentNumber

Depending on the type of segmentation, this parameter is handled differently:

For binary and fractional segmentations the segment number is automatically assigned and will be returned in this parameter. It is assigned from 0 onwards, i.e. the first segment added will have segment number 1, the second 2, etc.
For labelmap segmentations, the segment number is taken from this parameter and can be >= 0. If the segment number is already used, the method will overwrite an old segment with this number.

Returns: EC_Normal if adding was successful, error otherwise

◆ check()

virtual OFBool DcmSegmentation::check ( const OFBool checkFGStructure = OFTrue )

virtual

Perform some basic checking.

This method is also invoked when writing the object to a DICOM dataset or file.

Parameters

photometricInterpretation The color model to check (e.g. MONOCHROME2, PALETTE, etc.)

◆ importFromSourceImage() [1/2]

virtual OFCondition DcmSegmentation::importFromSourceImage	(	const OFString &	filename,

	)

virtual

Import Patient, Study, and Frame of Reference level information from the given item.

The method does only import Frame of Reference if Frame of Reference UID is found in the image (and no error is reported if not). The reason is that if the source images of the segmentation do have an FoR, the segmentation object must have the same one, so we must import it. If the images do not have an FoR, we must not try at all importing it. The current content of this object is not deleted before reading. If the log stream is set and valid the, the reason for any error might be obtained from the error/warning output.

Parameters

filename	Reference to DICOM dataset from which the document should be read
takeOverCharset	If OFTrue (default), Specific Character Set is taken over from imported dataset. If it's not present or empty (invalid), the attribute will not be present in this class either.

Returns: EC_Normal if successful, an error code otherwise

virtual

Import Patient, Study, and Frame of Reference level information from the given item.

The method does only import Frame of Reference if Frame of Reference (FoR) UID is found in the image (and no error is reported if not). The reason is that if the source images of the segmentation do have an FoR, the segmentation object must have the same one, so we must import it. If the images do not have an FoR, we must not try at all importing it. If the log stream is set and valid the, the reason for any error might be obtained from the error/warning output.

Parameters

dataset	Reference to DICOM dataset from which the document should be read
takeOverCharset	If OFTrue (default), Specific Character Set is taken over from imported dataset. If it's not present or empty (invalid), the attribute will not be present in this class either.
