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.
rc	AT_RECT	An AT_RECT struct specifying the rectangular portion of image to be processed.
nType	WORD	An IG_NOISE constant such as IG_NOISE_LINEAR, IG_NOISE_GAUSSIAN.
dblStrength	DOUBLE	From 0.0 to 127.0, specifying the degree of noise alteration to introduce into affected pixels.
nHitRate	INT	Set = 1 to add noise to all pixels, > 1 to skip pixels, only adding noise to some. Larger values cause fewer pixels to be affected. Valid range is from 1 to 500.
dblSigma	DOUBLE	Used with IG_NOISE_GAUSSIAN; the valid range is from 0.1 to 25.0.
nColorChannel	AT_MODE	An IG_COLOR_COMP_ constant. See file accucnst.h for a complete list.
nErrCount	AT_ERRCOUNT	The number of ImageGear errors that occurred during this function call.
lpfnUpdateProc	LPFNIGGUI_FX_UPDATE	A pointer to the function that is called when the 'Apply' button is clicked.
