nPointCount |
The value of the attribute "Number of Graphic Points" (0070,0021) in the "Graphic Annotation Module". |
|
|
pAnnPoints |
Pointer to an array of DICOMANNPOINT structures, which represent the points of the graphical object. This member is based on the "Graphic Data" (0070,0022) attribute in the "Graphic Annotation Module". |

Comments
The members of this structure are based on some of the attributes of the "Graphic Annotation Module", please see "Graphic Annotation Module Attributes" in the DICOM standard for more details.
Special note about the following members: pszLayerName and pAnnPoints:
When you call a function, which updates this structure (ex. LDicomDS::GetGraphicObjectInfo), LEADTOOLS will fill these members with pointers to the internal memory, which LEADTOOLS manages. You must not free these pointers. When you call a function, which updates internal data from the structure you provide (ex. LDicomDS::SetGraphicObjectInfo), LEADTOOLS expects you to fill these members with pointers to memory that you have allocated and that you manage. You must free these pointers when they are no longer needed.
