Members:

Name	Type	Description
cbSize	DWORD	Specifies the length, in bytes, of the structure.
uFlags	UINT	A set of bit flags you can use to initialize the dialog box.
hIGear	HIGEAR	A handle of an image.
hWnd	HWND	A handle of the window to update.
lpszTitle	LPCHAR	A dialog title.
nBits	UINT	A number of bits per pixel after reduction.
nReduceType	UINT	A type of color reduction (see IG_IGGUI_IP_COLOR_REDUCE_ constants in accucnst.h file).
nLevel	INT	A threshold value for dithering, 0 to 255.
nMaxColors	UINT	A maximum number of colors (that is, maximum number of unique pixel values) you want in the resulting image. Must be between 16 and 256.
bFastRemap	BOOL	TRUE if you want the reduction algorithm optimized for speed. FALSE if you want the algorithm optimized for quality.
nThreshold	UINT	An integer value that specifies which pixel values will be changed to black, and which pixel values will be changed to white. Pixels with values greater than nThreshold will be changed to white, and pixels that have values less than nThreshold will be changed to black.
nOption	AT_MODE	A constant of type AT_MODE, such as IG_REDUCE_BITONAL_AVE, that specifies what type of reduction to perform. See accucnst.h for the complete list.
nWeightR	UINT	These values are only used if nOption is set to IG_REDUCE_BITONAL_WEIGHTED. The range of values is between 0 and 255.
nWeightG	UINT	The range of values is between 0 and 255.
nWeightB	UINT	The range of values is between 0 and 255.
nErrCount	AT_ERRCOUNT	The number of ImageGear errors that occurred during this function call.
lpfnUpdateProc	LPFNIGGUI_IP_UPDATE	A pointer to the function that is called when the 'Apply' button is clicked.
