LDialogImageEffect::DoModalStitch

#include "ltwrappr.h"

virtual L_INT LDialogImageEffect::DoModalStitch(hWndOwner)

HWND hWndOwner;

/* handle of the window which owns the dialog */

Displays the Stitch dialog box for composing images. Use this dialog to produce a new bitmap that is composed of 1 or more source bitmaps.

Parameter	Description
hWndOwner	Handle of the window which owns the dialog.

Returns

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

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