LAnnotation::GetRotateOptions

#include "ltwrappr.h"

L_INT LAnnotation::GetRotateOptions(pRotateOptions, uStructSize)

pANNROTATEOPTIONS pRotateOptions;	/* pointer to a structure */
L_UINT uStructSize;	/* size of the ANNROTATEOPTIONS structure */

Gets the rotation options for the specified annotation object. This function is available in the Document/Medical Toolkits.

Parameter	Description
pRotateOptions	Pointer to an ANNROTATEOPTIONS structure that specifies the rotate options to be set.
uStructSize	Size in bytes, of the structure pointed to by pRotateOptions, for versioning. Use sizeof(ANNROTATEOPTIONS).

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function is one of the new functions being introduced as part of Version 14.5. Use this function to get the rotation options of any annotation object, including the automation object. To use this function, declare a variable a type ANNROTATEOPTIONS, and pass the address of this variable as the second argument. For more information, refer to the documentation for the structure ANNROTATEOPTIONS.

For Version 14.5, this functionality can be enabled using the following code snippet:

L_VOID ExampleEnableOption(LAnnAutomation& annAutomation)
{
   L_UINT nRet, uOptions = 0;
   nRet = annAutomation.GetOptions( &uOptions);
   nRet = annAutomation.SetOptions( uOptions | OPTIONS_NEW_ROTATE);
}
