Detailed Description

an item of the graphic object sequence in a presentation state (internal use only).

This class manages the data structures comprising one item of the Graphic Object Sequence which is contained in the Graphic Annotation Sequence in a Presentation State object.

Member Function Documentation

clone()

DVPSGraphicObject * DVPSGraphicObject::clone ( )

inline

clone method.

Returns

a pointer to a new DVPSGraphicObject object containing a copy of this object.

getAnnotationUnits()

DVPSannotationUnit DVPSGraphicObject::getAnnotationUnits

(

)

gets the graphic annotation units.

Returns

annotation units

getGraphicType()

DVPSGraphicType DVPSGraphicObject::getGraphicType

(

)

gets the graphic type of this graphic object.

Returns

graphic type

getNumberOfPoints()

size_t DVPSGraphicObject::getNumberOfPoints

(

)

gets the number of graphic points.

Returns

number of graphic points

getPoint()

OFCondition DVPSGraphicObject::getPoint	(	size_t	idx,
		Float32 &	x,
		Float32 &	y
	)

gets one point from the graphic data.

Parameters

idx	index of the graphic point, must be < getNumberOfPoints();
x	upon success the x value of the point is returned in this parameter
y	upon success the y value of the point is returned in this parameter

Returns

EC_Normal if successful, an error code otherwise.

isFilled()

OFBool DVPSGraphicObject::isFilled

(

)

checks if the graphic is filled

Returns

OFTrue if graphic is filled.

read()

OFCondition DVPSGraphicObject::read

(

DcmItem &

dset

)

reads a graphic object from a DICOM dataset.

The DICOM elements of the Graphic Object item are copied from the dataset to this object. The completeness of the item (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 item of the GraphicObjectSequence from which the data is to be read

Returns

EC_Normal if successful, an error code otherwise.

setData()

OFCondition DVPSGraphicObject::setData	(	size_t	number,
		const Float32 *	data,
		DVPSannotationUnit	unit
	)

sets the graphic data for this graphic object.

Parameters

number	number of graphic points in parameter "data"
data	pointer to an array of Float32 values with a size of (at least) 2*number. The values are copied into the graphic object.
unit	the graphic annotation units for this data.

Returns

EC_Normal if successful, an error code otherwise.

setFilled()

OFCondition DVPSGraphicObject::setFilled

(

OFBool

filled

)

sets the graphic filled status for the graphic object

Parameters

filled

OFTrue if graphic is filled, OFFalse otherwise.

Returns

EC_Normal if successful, an error code otherwise.

setGraphicType()

OFCondition DVPSGraphicObject::setGraphicType

(

DVPSGraphicType

gtype

)

sets the graphic type for the graphic object

Parameters

gtype

the graphic type

Returns

EC_Normal if successful, an error code otherwise.

write()

OFCondition DVPSGraphicObject::write

(

DcmItem &

dset

)

writes the graphic object managed by this object to a DICOM dataset.

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

Parameters

dset	the the item of the GraphicObjectSequence to which the data is written

Returns

EC_Normal if successful, an error code otherwise.
