## Detailed Description

the representation of one Curve in a DICOM image.

## Member Function Documentation

## ◆ clone()

DVPSCurve * DVPSCurve::clone | ( |  | ) |
| inline

clone method.

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

References DVPSCurve().

## ◆ getCurveAxisUnitsX()

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

References axisUnitsX.

## ◆ getCurveAxisUnitsY()

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

References axisUnitsY.

## ◆ getCurveDescription()

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

References curveDescription.

## ◆ getCurveGroup()

Uint8 DVPSCurve::getCurveGroup | ( |  | ) |
| inline

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

Returns
  the lower byte of the curve group

References curveGroup.

## ◆ getCurveLabel()

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

References curveLabel.

## ◆ getNumberOfPoints()

size_t DVPSCurve::getNumberOfPoints | ( |  | ) |
| inline

gets the number of points in the curve.

Returns
  number of points

References numberOfPoints.

## ◆ getPoint()

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.

## ◆ getTypeOfData()

DVPSCurveType DVPSCurve::getTypeOfData | ( |  | ) |
| inline

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

Returns
  type of data in curve

References typeOfData.

## ◆ read()

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.
