Member Function Documentation

DVPSCurve* DVPSCurve::clone (  )  [inline]

clone method.

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

Definition at line 57 of file dvpscu.h.

References DVPSCurve().

OFCondition DVPSCurve::read ( DcmItem dset,
Uint8  group 
)

reads a curve from a DICOM dataset.

The DICOM elements of the Graphic Object item are copied from the dataset to this object. The completeness of the curve (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 data is to be read
group lower byte of the curve repeating group to be read
Returns:
EC_Normal if successful, an error code otherwise.

Uint8 DVPSCurve::getCurveGroup (  )  [inline]

get group number of curve repeating group managed by this object.

Returns:
the lower byte of the curve group

Definition at line 77 of file dvpscu.h.

References curveGroup.

size_t DVPSCurve::getNumberOfPoints (  )  [inline]

gets the number of points in the curve.

Returns:
number of points

Definition at line 82 of file dvpscu.h.

References numberOfPoints.

DVPSCurveType DVPSCurve::getTypeOfData (  )  [inline]

gets the type of data in the curve (ROI or POLY).

Returns:
type of data in curve

Definition at line 87 of file dvpscu.h.

References typeOfData.

OFCondition DVPSCurve::getPoint ( size_t  idx,
double &  x,
double &  y 
)

gets one point from the curve data.

Parameters:
idx index of the curve 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.

const char* DVPSCurve::getCurveDescription (  )  [inline]

gets the curve description string if present.

If the description string is absent, this method returns NULL or an empty string.

Returns:
curve description

Definition at line 101 of file dvpscu.h.

References OFString::c_str(), and curveDescription.

const char* DVPSCurve::getCurveLabel (  )  [inline]

gets the curve label string if present.

If the label string is absent, this method returns NULL or an empty string.

Returns:
curve label

Definition at line 107 of file dvpscu.h.

References OFString::c_str(), and curveLabel.

const char* DVPSCurve::getCurveAxisUnitsX (  )  [inline]

gets the curve axis units string for the X dimension if present.

If the string is absent, this method returns NULL or an empty string.

Returns:
curve description

Definition at line 113 of file dvpscu.h.

References axisUnitsX, and OFString::c_str().

const char* DVPSCurve::getCurveAxisUnitsY (  )  [inline]

gets the curve axis units string for the Y dimension if present.

If the string is absent, this method returns NULL or an empty string.

Returns:
curve description

Definition at line 119 of file dvpscu.h.
