Detailed Description

the list of displayed area selections contained in a presentation state (internal use only).

This class manages the data structures comprising one complete displayed area selection sequence contained in a presentation state object.

Member Function Documentation

clear()

void DVPSDisplayedArea_PList::clear

(

)

reset the object to initial state.

After this call, the object is in the same state as after creation with the default constructor.

clone()

DVPSDisplayedArea_PList* DVPSDisplayedArea_PList::clone ( )

inline

clone method.

Returns

a pointer to a new DVPSDisplayedArea_PList object containing a deep copy of this object.

createDisplayedArea()

DVPSDisplayedArea* DVPSDisplayedArea_PList::createDisplayedArea	(	DVPSReferencedSeries_PList &	allReferences,
		const char *	sopclassUID,
		const char *	instanceUID,
		unsigned long	frame,
		unsigned long	numberOfFrames,
		DVPSObjectApplicability	applicability
	)

finds or creates a displayed area selection SQ item with an applicability controlled by the applicability, instanceUID and frame parameters.

The displayed area selection sequence is rearranged such that all other referenced images/frames keep their old displayed area settings.

Parameters

allReferences	list of series/instance references registered for the presentation state.
sopclassUID	SOP class UID of the current image
instanceUID	SOP instance UID of the current image
frame	number of the current frame
numberOfFrames	number of frames of the current image
applicability	applicability of the new displayed area selection

Returns

pointer to a displayed area selection object from the list that matches the applicability parameters. NULL is returned if out of memory.

findDisplayedArea()

DVPSDisplayedArea* DVPSDisplayedArea_PList::findDisplayedArea	(	const char *	instanceUID,
		unsigned long	frame
	)

checks if an displayed area selection exists for the given image and frame.

Parameters

instanceUID	SOP instance UID of the current image
frame	number of the current frame

Returns

pointer to the displayed area if it exists, NULL otherwise.

read()

OFCondition DVPSDisplayedArea_PList::read

(

DcmItem &

dset

)

reads a list of displayed area selections (DisplayedAreaSelectionSequence) from a DICOM dataset.

The DICOM elements of the displayed area selection item are copied from the dataset to this object. The completeness of all items (presence of all required elements, value multiplicity) is checked. If this method returns an error code, the object is in undefined state afterwards.

Parameters

dset	the DICOM dataset from which the sequence is to be read

Returns

EC_Normal if successful, an error code otherwise.

rotateAndFlip()

void DVPSDisplayedArea_PList::rotateAndFlip	(	DVPSRotationType	rotationFrom,
		OFBool	isFlippedFrom,
		DVPSRotationType	rotationTo,
		OFBool	isFlippedTo
	)

adjusts all displayed area coordinates for the rotation and flipping status of the image.

Parameters

rotationFrom	previous rotation
isFlippedFrom	previous flip status
rotationTo	new rotation
isFlippedTo	new flip status

size()

size_t DVPSDisplayedArea_PList::size ( ) const

inline

gets the number of displayed area selections in this list.

Returns

the number of displayed area selections.

write()

OFCondition DVPSDisplayedArea_PList::write

(

DcmItem &

dset

)

writes the list of displayed area selections managed by this object to a DICOM dataset.

Copies of the DICOM elements managed by this object are inserted into the DICOM dataset.

Parameters

dset	the DICOM dataset to which the DisplayedAreaSelectionSequence is written

Returns

EC_Normal if successful, an error code otherwise.
