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.
