## Detailed Description

  sopclassUID | SOP class UID of the current image
  instanceUID | SOP instance UID of the current image
  frame | number of the current frame
  applicability | applicability of the new text object
  graphic | the graphic object to be inserted. If NULL, a new graphic object is created. If a pointer to an object is passed in this parameter, it gets owned by this graphic annotation object and will be deleted upon destruction of the annotation or if this method fails (returns NULL).

  a pointer to the new graphic object

## addTextObject()

DVPSTextObject * DVPSGraphicAnnotation_PList::addTextObject | ( | const char * | layer,

|  | DVPSTextObject * | text = NULL )

creates a new text object on the given layer.

Returns a pointer to the new text object. If no graphic layer with appropriate applicability exists, it is created. If the creation of the layer or text object fails, NULL is returned.

  instanceUID | SOP instance UID of the current image
  frame | number of the current frame
  applicability | applicability of the new text object
  text | the text object to be inserted. If NULL, a new text object is created. If a pointer to an object is passed in this parameter, it gets owned by this graphic annotation object and will be deleted upon destruction of the annotation or if this method fails (returns NULL).

Returns
  a pointer to the new text object
