IWICLeadBitmapEncoder::GetSubFormatFlags Method
See Also

Gets the encoder sub-format flags for a particular sub-format and pixel format.

Syntax

 
HRESULT GetSubFormatFlags(      
    WICPixelFormatGUID guidPixelFormat,
    UINT uSubFormatIndex,
    WICLeadSubFormatFlags *puFlags
);

Parameters

 
guidPixelFormat
[in] The pixel format GUID that the encoder is using.
uSubFormatIndex
[in] An index into the sub-format array that is returned from GetSubFormats.
puFlags
[in,out] A pointer that receives the flags supported by the encoder sub-format and pixel format.

Return Values

Returns S_OK if successful, or an error value otherwise.

Remarks

This method returns the WICLeadSubFormatFlags for a particular sub-format of a LEAD encoder.
You must first call GetSubFormats to get the array of valid sub-formats for the particular LEAD encoder. Then call GetSubFormatFlags on a particular member of the sub-format array to get the flags for the sub-format. The sub-format flags will be a logical "or" of zero or more of the WICLeadSubFormatFlags. Note that the uSubFormatIndex argument is an index into the sub-format array, and NOT a WICLeadSubFormat constant.

The (sub-format)/(sub-format flag) pair is unique, and has a name that is obtained by calling  the GetSubFormatFriendlyName method.  For more information, see GetSubFormats.
