LDialogImageEffect::DoModalStitch

Summary

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.

Syntax

#include "ltwrappr.h"

virtual L_INT LDialogImageEffect::DoModalStitch(hWndOwner)

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

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.
