Displays the Erosion Filter dialog box, and gets the options for LBitmap::BinaryFilter. This function is available in the Document/Medical toolkits.
#include "ltwrappr.h"
virtual L_INT LDialogImageEffect::DoModalErosionFilter(hWndOwner)
Handle of the window which owns the dialog.
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. |
< 1 | An error occurred. Refer to Return Codes. |
LDialogImageEffect::SetErosionFilterParams must be called before using this function to set the initial values for the dialog. You get the updated EROSIONFILTERDLGPARAMS with the values entered by the user through the dialog by using LDialogImageEffect::GetErosionFilterParams.
