Method Detail

getGraphicType

java.lang.String getGraphicType()

Returns the Graphic Type.
DICOM Tag: (0070,0023)
Tag Name: Graphic Type
When annotation applies to an image, this attribute defines the type of geometry of the annotated region of interest. The following return Values are specified for image spatial coordinate geometries:

"POINT"

a single pixel denoted by a single (column,row) pair.

"MULTIPOINT"

multiple pixels each denoted by an (column,row) pair.

"POLYLINE"

a closed polygon with vertices denoted by (column,row) pairs.

"CIRCLE"

a circle defined by two (column,row) pairs. The first point is the central pixel. The second point is a pixel on the perimeter of the circle.

"ELLIPSE"

an ellipse defined by four pixel (column,row) pairs, the first two points specifying the endpoints of the major axis and the second two points specifying the endpoints of the minor axis of an ellipse.

Returns:

the Graphic Type.

getGraphicData

float[] getGraphicData()

Returns the Graphic Data.
DICOM Tag: (0070,0022)
Tag Name: Graphic Data

Depending on the Graphic Type different sized float arrays will be returned:

POINT

a single pixel denoted by a single (column,row) pair.

          graphicData[0] = column;
          graphicData[1] = row;
      

MULTIPOINT

multiple pixels each denoted by an (column,row) pair.

          graphicData[0] = column_1;
          graphicData[1] = row_1;
          .
          .
          graphicData[n-1] = column_X;
          graphicData[n] = row_X;
      

POLYLINE

a closed polygon with vertices denoted by (column,row) pairs.

          graphicData[0] = column_1;
          graphicData[1] = row_1;
          .
          .
          graphicData[n-1] = column_X;
          graphicData[n] = row_X;
      

CIRCLE

a circle defined by two (column,row) pairs. The first point is the central pixel. The second point is a pixel on the perimeter of the circle.

          graphicData[0] = central_pixel_column;
          graphicData[1] = central_pixel_row;
          graphicData[2] = perimeter_point_column;
          graphicData[3] = perimeter_point_row;
      

ELLIPSE

an ellipse defined by four pixel (column,row) pairs, the first two points specifying the endpoints of the major axis and the second two points specifying the endpoints of the minor axis of an ellipse.

          graphicData[0] = MAJOR_axis_X_column;
          graphicData[1] = MAJOR_axis_X_row;
          graphicData[2] = MAJOR_axis_Y_column;
          graphicData[3] = MAJOR_axis_Y_row;
          graphicData[4] = minor_axis_X_column;
          graphicData[5] = minor_axis_X_row;
          graphicData[6] = minor_axis_Y_column;
          graphicData[7] = minor_axis_Y_row;
      

Returns:

the Graphic Data.
