SetMRCPreserveSmoothing Method (GdPicturePDF)

In This Topic
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.

Syntax

Parameters

PreserveSmoothing
Set this parameter to false to dramatically reduce produced file size, but get a less contrasting text. Otherwise set it to true.
Remarks
This attribute is only relevant when compressing images using the MRC Compression mechanism.

Just to inform you, that this value is valid continuously when processing each image until you change it. It is not related to the currently loaded document.
