Syntax

HRESULT GetEncoderParameterList(
  UINT                size,
  EncoderParameters* Params
);

Parameters

• size
  [in] A UINT value specifying the size, in bytes, of the parameter array in Params.

This method may return E_NOTIMPL if it fails.

Remarks

The following code shows a parameter list returned by IImageEncoder::GetEncoderParameterList.

Count = 2
Params[0] = {
  ENCODER_COMPRESSION, 
  3, 
  EncoderParameterValueTypeLong, 
  { // Value
    EncoderValueCompressionLZW,
    EncoderValueCompressionRle,
    EncoderValueCompressionNone
  }
}
Params[1] = {
  ENCODER_SAVE_FLAG,
  1,
  EncoderParameterValueTypeLong,
  { // Value
    EncoderValueMultiFrame
  }
}
