The STITCHDLGPARAMS structure provides information used to initialize the dialog box created by the L_DlgStitch function. After the user closes the dialog box, this structure is updated with information about the user's selections.

Member	Description
uStructSize	Size of this structure, in bytes. Use the sizeof operator to calculate this value.
pResultingBitmap	Pointer to a valid bitmap handle to be updated with the bitmap resulting from the stitch dialog. If L_DlgStitch returns SUCCESS_DLG_EXPORTANDEXIT, then this bitmap is allocated and the user is responsible for freeing this handle using L_FreeBitmap.
uResultingBitmapStructSize	Size of the BITMAPHANDLE structure referencing pResultingBitmap.
nResultingBitmapWidth	Value that indicates the resulting image's width in pixels. This value is used to initialize the Width edit box in the Image Attributes sub dialog.
nResultingBitmapHeight	Value that indicates the resulting image's height in pixels. This value is used to initialize the Height edit box in the Image Attributes sub dialog.
nResultingBitmapBitsPerPixel	Value representing the image depth of the resulting image. This may be 1, 4, 8, 16, 24 bpp. This value is used to initialize the Depth combo box in the Image Attributes sub dialog.
nRes	Horizontal and vertical resolution, in dots per inch. This value is used to initialize the Resolution edit box in the Image Attributes sub dialog.
crBackGround	The COLORREF value that specifies the background color for the resulting image. This value is used to initialize the Back-Color color picker in the Image Attributes sub dialog.
pBitmapList	Pointer to a DLGBITMAPLIST structure that is used to initialize the image picker in the dialog. The pszDescription member of the DLGBITMAPLIST structure will be used as a tool tip for each image in the image picker when the mouse hovers over it.
hWindowIcon	Handle to the icon to use for the print window©s system menu. Pass NULL to use the default icon.
nCmdShow	Flag that indicates the display state of the stitch window. This is the same flag passed to the ShowWindow windows C DLL function. Please refer to the Microsoft SDK documentation © Windows User Interface © ShowWindow for more information. Possible values include:
	Value	Meaning
	SW_SHOW	Preview window is visible
	SW_HIDE	Preview window is hidden

uDlgFlags	User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
	Value	Meaning
	DLG_STITCH_NOPAGESETUPONSTART	[0x00000001] Don©t display the image attributes sub dialog at stitch dialog startup.
pfnHelpCallback	Pointer to an optional help callback function. If you do not wish to provide help to this dialog, use NULL as the value of this parameter. To provide help to this dialog, use the function pointer as the value of this parameter. The callback function must adhere to the prototype described in LTCOMMDLGHELPCB.
pHelpCallBackUserData	Void pointer that you can use to pass one or more additional parameters that the callback function needs. To use this feature, assign a value to a variable or create a structure that contains as many fields as you need. Then, in this parameter, pass the address of the variable or structure, casting it to L_VOID *. The callback function, which receives the address in its own pHelpCallBackUserData parameter, can cast it to a pointer of the appropriate data type to access your variable or structure. If the additional parameters are not needed, you can pass NULL in this parameter.
