LDialogDocument::DoModalDotRemove

#include "ltwrappr.h"

virtual L_INT LDialogDocument::DoModalDotRemove(hWndOwner)

Displays the Dot Remove dialog box, and gets the options for LBitmap::DotRemove. This function is available in the Document/MedicalDocument/Medical toolkits.

Parameters

HWND hWndOwner

Handle of the window which owns the dialog.

Returns

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.

Comments

LDialogDocument::SetDotRemoveParams must be called before using this function to set the initial values for the dialog. You can get the updated DOTREMOVEDLGPARAMS with the values entered by the user through the dialog by using LDialogDocument::GetDotRemoveParams.

The LBitmap::DotRemove function only works with 1-bit images. If you provide a bitmap in the LDialogDocument class, it must be a 1-bit bitmap.
