IWICBitmapCodecInfo::GetColorManagementVersion method (wincodec.h)

Retrieves the color management version number the codec supports.

Syntax

HRESULT GetColorManagementVersion(
  [in]      UINT  cchColorManagementVersion,
  [in, out] WCHAR *wzColorManagementVersion,
  [in, out] UINT  *pcchActual
);

Parameters

[in] cchColorManagementVersion

Type: UINT

The size of the version buffer. Use 0 on first call to determine needed buffer size.

[in, out] wzColorManagementVersion

Type: WCHAR*

Receives the color management version number. Use NULL on first call to determine needed buffer size.

[in, out] pcchActual

Type: UINT*

The actual buffer size needed to retrieve the full color management version number.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The usage pattern for this method is a two call process. The first call retrieves the buffer size needed to retrieve the full color management version number by calling it with cchColorManagementVersion set to 0 and wzColorManagementVersion set to NULL. This call sets pcchActual to the buffer size needed. Once the needed buffer size is determined, a second GetColorManagementVersion call with cchColorManagementVersion set to the buffer size and wzColorManagementVersion set to a buffer of the appropriate size will retrieve the pixel formats.
