The PICTURIZEDLGPARAMS structure provides information used to initialize the dialog box created by the L_DlgPicturize 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.
pBitmap	Pointer to the bitmap handle that references the bitmap used for preview or processing.
pszPath	A string that contains the full path to the directory that contains the images. Only images from this directory will be used. Images in any subdirectories will NOT be used.
nCellWidth	A variable to be updated with the width of the images used to reconstruct the image. Possible values range from 1 to nBitmapWidth.
nCellHeight	A variable to be updated with the height of the images used to reconstruct the image. Possible values range from 1 to nBitmapHeight.
uResize	Flags that control the behavior of the process. Possible values are given below. These values can be combined using OR (\|).
	Value	Meaning
	PICTURIZE_RESIZE	[0x0002] Resize the images that are not the required size.
	PICTURIZE_RESAMPLE	[0x0004] Resample the images that are not the required size.
	PICTURIZE_ONCE	[0x0010] Use the image only once throughout the process.
	PICTURIZE_EQUALUSAGE	[0x0020] Use all images equally. That is, before an image will be used twice, all other images must be used at least once.
	PICTURIZE_BESTFIT	[0x0040] Images will be resized to fit the image if the bitmap width or height is not a multiple of nCellWidth/nCellHeight.
	0	The picturize process will not use any of the above flags. It will: reload all the files each time you look for a rectangle to substitute and ignore all the images present in pszPath if their size is not nCellWidth x nCellHeight

nBitmapWidth	A variable to be updated with the maximum possible cell width. The value must be greater than zero.
nBitmapHeight	A variable to be updated with the maximum possible cell height. The value must be greater than zero.
uDlgFlags	User interface flags for this dialog, which determine the layout and action of the dialog. Possible values are:
	Value	Meaning
	DLG_PICTURIZE_AUTOPROCESS	[0x00000001] process the image on OK. The pBitmap member of this structure should contain a valid bitmap.
	DLG_PICTURIZE_SHOW_CONTEXTHELP	[0x00000002] dialog should contain a context sensitive help icon.
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.
