#include "l_bitmap.h"

L_LTDLG_API L_INT L_DlgStitch(hWndOwner, pDlgParams)

Parameters

L_HWND hWndOwner

Handle of the window that owns the dialog.

LPSTITCHDLGPARAMS pDlgParams

Pointer to a STITCHDLGPARAMS structure to initialize the stitch dialog.

Comments

The Stitch dialog.

Returns

Value	Meaning
SUCCESS_DLG_EXPORTANDEXIT	"Exit and Export" was selected from the menu and the dialog exited successfully. The pResultingBitmap member of the STITCHDLGPARAMS structure will be updated with the exported bitmap. The user is responsible for freeing the pResultingBitmap member.
