SetMRCPreserveSmoothing Method (GdPicturePDF)
Enables the use of enhanced smoothing technique when processing the image compression by the MRC engine, for example using the
GdPicturePDF.AddImageFromGdPictureImage method.
Smoothing improves the contrast of the image by reducing noise. That means the produced image is less pixelated, but it's file size can increase. The predefined value is true.

Parameters
- PreserveSmoothing
- Set this parameter to false to dramatically reduce produced file size,
but get a less contrasting text. Otherwise set it to true.
