Syntax

HRESULT FilterNoise([in]  RECT*  pRect,
                    [in]  ULONG  nLevel,
                    [in]  ULONG  nFlags);

Parameters

pRect

[in] Pointer to the RECT structure which defines the rectangular area where the function should be applied. If this parameter is NULL, the entire page will be processed.

Note:

Please note that partial processing of an area of a page is not supported for all image formats. For example, it is not supported for indexed images, because pixels in such images do not contain a color, but an index into a color table (or palette) which is common for the entire page

nLevel

[in] Specifies noise level.

nFlags

[in] Specifies the type of the filter. Could be one of the following Noise types.

Return Value

Returns S_OK if operation was successful or error code in other cases.
