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.
nAngle	INT	An angle to rotate in degrees; a positive value.
nMode	AT_MODE	An integer variable of type AT_MODE defined in accucnst.h. The value can be either IG_ROTATE_CLIP or IG_ROTATE_EXPAND, indicating whether to clip the rotated image to keep the image bitmap the same size, or expand the size of the bitmap to retain the entire rotated image.
lpBkgndColor	LPAT_PIXEL	A far pointer to the RGB or pixel value that specifies the background color to be used in the displaced areas after the image has been rotated.
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.
