#include "ltwrappr.h"
virtual L_INT LDialogImageEffect::DoModalDilationFilter(hWndOwner)

| Value | Meaning |
|---|---|
| SUCCESS_DLG_OK | The "OK" button was pressed, and the dialog exited successfully. |
| SUCCESS_DLG_CANCEL | The "Cancel" button was pressed, and the dialog exited successfully. |

LDialogImageEffect::SetDilationFilterParams must be called before using this function to set the initial values for the dialog. You can get the updated DILATIONFILTERDLGPARAMS with the values entered by the user through the dialog by using LDialogImageEffect::GetDilationFilterParams.
