L_LTDLG_API L_INT L_DlgJPEGWebTuner(hWndOwner, pDlgParams)
Displays the JPEG Web Tuner dialog box, and gets the tuning options used by L_SaveBitmap.
Handle of the window, which owns the dialog.
Pointer to a JPEGWEBTUNERDLGPARAMS structure to be updated with the values entered by the user through the dialog. Set members of this structure, before calling this function, to set the dialogs initial values.
| 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. |
