LAnnAutomation::GetPointOptions

Summary

Gets the options for the specified Automation annotation object.

Syntax

#include "ltwrappr.h"

virtual L_INT LAnnAutomation::GetPointOptions(pPointOptions, uStructSize)

Parameters

pANNPOINTOPTIONS pPointOptions

Pointer to an ANNPOINTOPTIONS structure to be updated with the various point appearance options for the specified annotation object.

L_UINT uStructSize

Size in bytes, of the structure pointed to by pPointOptions, for versioning. Use sizeof(ANNPOINTOPTIONS).

Returns

Value Meaning
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 of type ANNPOINTOPTIONS, and pass the address of this variable as the second argument. For more information, see the documentation for the structure ANNPOINTOPTIONS.
