LDialogWeb::DoModalJPEGWebTuner

#include "ltwrappr.h"

virtual L_INT LDialogWeb::DoModalJPEGWebTuner (hWndOwner)

Displays the JPEG Web Tuner dialog box, and gets the tuning options used by LBitmapBase::Save.

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_CLOSE The "Close" 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

LDialogWeb::SetJPEGWebTunerParams must be called before using this function to set the initial values for the dialog. You can get the updated JPEGWEBTUNERDLGPARAMS with the values entered by the user through the dialog by using LDialogWeb::GetJPEGWebTunerParams.
