L_LTANN_API L_INT L_AnnGetRotateOptions(hObject, pRotateOptions, uStructSize)
Gets the rotation options for the specified annotation object.
Handle to the annotation object.
Pointer to an ANNROTATEOPTIONS structure that specifies the rotate options to set.
Size in bytes, of the structure pointed to by pRotateOptions
, for versioning. Use sizeof(ANNROTATEOPTIONS).
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
Use this function to get the rotation options of any annotation object, including the automation object. To use this function, declare a variable of type ANNROTATEOPTIONS, and pass the address of this variable as the second argument. For more information, refer to the documentation for the structure ANNROTATEOPTIONS.
Required DLLs and Libraries
Win32, x64.
This example displays if the annotation object displays
rotate handles. If displaying rotate handles, the object
is changed so that it does not display rotate handles.
If not displaying rotate handles, the object is changed
so that it displays rotate handles.
