LAnnAutomation::GetPointOptions
#include "ltwrappr.h"
static L_INT LAnnAutomation::GetPointOptions(pPointOptions, uStructSize)
pANNPOINTOPTIONS pPointOptions; |
/* pointer to an ANNPOINTOPTIONS structure that specifies various point options */ |
L_UINT uStructSize; |
/* Size in bytes, of the structure pointed to by pPointOptions, for versioning. Use sizeof(ANNPOINTOPTIONS). */ |
Gets the options for the specified Automation annotation object. This function is available in the Document/Medical Toolkits.
Parameter |
Description |
pPointOptions |
Pointer to an ANNPOINTOPTIONS structure to be updated with the various point appearance options for the specified annotation object. |
uStructSize |
Size in bytes, of the structure pointed to by pPointOptions, for versioning. Use sizeof(ANNPOINTOPTIONS). |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
Use this function to get the point appearance options of an annotation automation object. To use this function, declare a variable a type ANNPOINTOPTIONS, and pass the address of this variable as the second argument. For more information, see the documentation for the structure ANNPOINTOPTIONS.
