Detailed Description

the list of curve and overlay activation layers contained in a presentation state (internal use only).

This class manages the data structures comprising the list of curve activation layers and overlay activation layers (all instances of the Curve Activation Layer Module and Overlay Activation Layer Module repeating elements) contained in a Presentation State object.

Member Function Documentation

void DVPSOverlayCurveActivationLayer_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.

DVPSOverlayCurveActivationLayer_PList* DVPSOverlayCurveActivationLayer_PList::clone ( ) [inline]

clone method.

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

OFCondition DVPSOverlayCurveActivationLayer_PList::createFromImage	(	DcmItem &	dset,
		DVPSGraphicLayer_PList &	gLayerList,
		DVPSOverlay_PList &	overlayList,
		DVPSoverlayActivation	overlayActivation,
		OFBool	curveActivation,
		DVPSGraphicLayering	layering
	)

create graphic layers and activations for DICOM image.

This method is used when a default presentation state for a DICOM image is created. Depending on the given flags, graphic layer and curve/overlay activations for the curves and overlays present in the DICOM dataset are created. If this method returns an error code, the object is in undefined state afterwards.

Parameters:

dset	the DICOM dataset containing the image IOD
gLayerList	the list of graphic layers to be created
overlayList	the list of overlays internal to the presentation state
overlayActivation	flag defining how overlays should be handled
curveActivation	flag defining how curves should be handled
layering	flag defining how graphic layers should be created

Returns:: EC_Normal upon success, an error code otherwise.

Uint16 DVPSOverlayCurveActivationLayer_PList::getActivationGroup	(	const char *	layer,
		size_t	idx,
		OFBool	isCurve
	)

gets the repeating group of the overlay/curve activation with the given index on the given layer.

If the activation or the graphic layer does not exist, 0 is returned.

Parameters:

layer	name of the graphic layer
idx	index of the object, must be < getNumberOfActivations(layer, isCurve)
isCurve	if OFTrue, curves are searched, otherwise overlays are searched.

Returns:: the repeating group number of the activation

const char* DVPSOverlayCurveActivationLayer_PList::getActivationLayer ( Uint16 group )

get activation layer name of the given repeating group.

Returns:: a pointer to the activation layer name if found, NULL otherwise.

size_t DVPSOverlayCurveActivationLayer_PList::getNumberOfActivations	(	const char *	layer,
		OFBool	isCurve
	)

returns the number of activations for the given graphic layer and object type (curve or overlay).

This method does not check whether an image object is attached to the presentation state and if all activations really have a matching curve structure in the attached image.

Parameters:

layer	name of the graphic layer
isCurve	if OFTrue, curves are counted, otherwise overlays are counted.

Returns:: number of curves or overlays on the given layer.

OFCondition DVPSOverlayCurveActivationLayer_PList::read ( DcmItem & dset )

reads the curve and overlay activations from a DICOM dataset.

The DICOM elements of the activations are copied from the dataset to this object. If this method returns an error code, the object is in undefined state afterwards.

Parameters:

dset	the DICOM dataset from which the activations are to be read

Returns:: EC_Normal if successful, an error code otherwise.

void DVPSOverlayCurveActivationLayer_PList::removeLayer ( const char * name )

deletes all activation belonging to the given activation layer name.

Parameters:

name	name of the deleted activation layer

void DVPSOverlayCurveActivationLayer_PList::renameLayer	(	const char *	oldName,
		const char *	newName
	)

renames the activation layer name in all activations with a matching old activation layer name.

Required to keep the presentation consistent when a graphic layer is renamed.

Parameters:

oldName	the old activation layer name
newName	the new activation layer name

OFCondition DVPSOverlayCurveActivationLayer_PList::setActivation	(	Uint16	group,
		const char *	layer
	)

set activation layer for given repeating group.

The activation is created if necessary and the layer name is assigned. This method check if a valid repeating group number is passed and returns an error code otherwise.

Returns:: EC_Normal if successful, an error code otherwise.

OFBool DVPSOverlayCurveActivationLayer_PList::usesLayerName ( const char * name )

checks if the given layer name is used for any of the activation layers managed by this object.

Parameters:

name	name of the layer

Returns:: OFTrue if name is used

OFCondition DVPSOverlayCurveActivationLayer_PList::write ( DcmItem & dset )

writes the curve and overlay activations 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 activations are written

Returns:: EC_Normal if successful, an error code otherwise.
