Detailed Description

the list of referenced images contained in a presentation state (internal use only).

This class manages the data structures comprising one complete Reference Image Sequence which is contained in one item of the Referenced Series Sequence in a Presentation State object.


Member Function Documentation

OFCondition DVPSReferencedImage_PList::addImageReference ( const char *  sopclassUID,
const char *  instanceUID,
const char *  frames = NULL 
)

add a new image reference.

Checks if the referenced SOP instance UID already exists in this sequence. If it exists, an error code is returned. Otherwise a new image reference is created and added to the ReferencedImageSequence.

Parameters:
sopclassUIDthe SOP class UID of the image reference to be added.
instanceUIDthe SOP instance UID of the image reference to be added.
framesa list of frame numbers in DICOM IS format (integer numbers separated by '\' characters). Default: frame numbers absent. The frame numbers are required if the referenced image is a multiframe image.
OFCondition DVPSReferencedImage_PList::addImageReference ( const char *  sopclassUID,
const char *  instanceUID,
unsigned long  frame,
DVPSObjectApplicability  applicability 
)

add a new image reference.

Checks if the referenced SOP instance UID already exists in this sequence. If it exists, an error code is returned. Otherwise a new image reference is created and added to the ReferencedImageSequence.

Parameters:
sopclassUIDthe SOP class UID of the image reference to be added.
instanceUIDthe SOP instance UID of the image reference to be added.
framethe frame number of the image reference (current image) to be added.
applicabilitythe applicability of the image reference (DVPSB_currentFrame or DVPSB_currentImage)
Returns:
EC_Normal if successful, an error code otherwise.

reset the object to initial state.

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

clone method.

Returns:
a pointer to a new DVPSReferencedImage_PList object containing a deep copy of this object.

checks if an image reference with the given SOP instance UID exists in this ReferencedImageSequence.

Parameters:
sopinstanceuidthe SOP instance UID of the searched image reference
Returns:
a pointer to the matching DVPSReferencedImage if found, NULL otherwise.
OFCondition DVPSReferencedImage_PList::getImageReference ( size_t  idx,
OFString sopclassUID,
OFString instanceUID,
OFString frames 
)

gets an image reference with the given index.

Parameters:
idxindex, must be < size().
sopclassUIDthe SOP Class UID is returned in this string
instanceUIDthe SOP Instance UID is returned in this string
framesthe list of frames is returned in this string
Returns:
EC_Normal if successful, an error code otherwise.
OFBool DVPSReferencedImage_PList::isApplicable ( const char *  instanceUID,
unsigned long  frame 
)

checks if the object containing this list of image references is applicable to the given image and frame.

Parameters:
instanceUIDSOP instance UID of the current image
framenumber of the current frame
Returns:
OFTrue if applicable.
OFBool DVPSReferencedImage_PList::isValid ( OFString sopclassuid)

checks if images are referenced within this ReferencedImageSequence and whether all images share the same SOP class UID.

Parameters:
sopclassuidshould be an empty string when called. Returns the SOP class UID of the images in the list.
Returns:
OFTrue if the sequence is valid (correct), OFFalse otherwise.
OFBool DVPSReferencedImage_PList::matchesApplicability ( const char *  instanceUID,
unsigned long  frame,
DVPSObjectApplicability  applicability 
)

checks if the object containing this list of image references matches exactly the applicability defined by the instanceUID, frame and applicability parameters.

Parameters:
instanceUIDSOP instance UID of the current image
framenumber of the current frame
Returns:
OFTrue if matching.

reads a list of image references (ReferencedImageSequence) from a DICOM dataset.

The DICOM elements of the image references 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:
dsetthe DICOM dataset from which the sequence is to be read
Returns:
EC_Normal if successful, an error code otherwise.
void DVPSReferencedImage_PList::removeFrameReference ( const char *  sopinstanceuid,
unsigned long  frame,
unsigned long  numberOfFrames 
)

update the reference to the given image such that the given frame is not referenced any more.

Parameters:
sopinstanceuidthe SOP instance UID of the image reference
framethe frame reference
numberOfFramesthe number of frames of the image reference
void DVPSReferencedImage_PList::removeImageReference ( const char *  sopinstanceuid)

checks if an image reference with the given SOP instance UID exists in this ReferencedImageSequence and deletes it.

Parameters:
sopinstanceuidthe SOP instance UID of the image reference to be removed.
void DVPSReferencedImage_PList::removeImageReference ( DVPSReferencedSeries_PList allReferences,
const char *  instanceUID,
unsigned long  frame,
unsigned long  numberOfFrames,
DVPSObjectApplicability  applicability 
)

removes a reference to an image or frame.

If the current reference is empty ("global"), an explicit list of references is constructed from the list of series/instance references. The image or frame reference is removed from the total list of references in this object. If the only reference contained in this object is removed, the reference list becomes empty which means that the current reference becomes "global". This case must be handled by the caller.

Parameters:
allReferenceslist of series/instance references registered for the presentation state.
instanceUIDSOP instance UID of the current image
framenumber of the current frame
numberOfFramesthe number of frames of the current image
applicabilitythe applicability of the image reference to be removed (DVPSB_currentFrame or DVPSB_currentImage)
size_t DVPSReferencedImage_PList::size ( ) const [inline]

gets the number of image references in this list.

Returns:
the number of image references.

writes the list of image references managed by this object to a DICOM dataset.

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

Parameters:
dsetthe DICOM dataset to which the ReferencedImageSequence is written
Returns:
EC_Normal if successful, an error code otherwise.
