Gets the attributes of a text annotation object.
Parameter |
Description |
pGraphicAnnSQItem |
Pointer to an item element under the "Graphic Annotation Sequence" (0070,0001) in the "Graphic Annotation Module". |
uTextObjectIndex |
The index of the text annotation object whose attributes we want to retrieve. |
pTextObject |
Pointer to a structure which will be filled with the text annotation object attributes. |
uStructSize |
Size of the DICOMTEXTOBJECT structure. Pass sizeof(DICOMTEXTOBJECT). |
Returns
0 |
SUCCESS |
>0 |
An error occurred. Refer to Return Codes. |
Comments
This function will retrieve the attributes of a text object and store their values in the structure pointed to by pTextObject. pTextObject->uStructSize will be set to the value of the parameter uStructSize.
