PdfSaveOptions.InterpolateImages property

public bool InterpolateImages { get; set; }

Remarks

When the resolution of a source image is significantly lower than that of the output device, each source sample covers many device pixels. As a result, images can appear jaggy or blocky. These visual artifacts can be reduced by applying an image interpolation algorithm during rendering. Instead of painting all pixels covered by a source sample with the same color, image interpolation attempts to produce a smooth transition between adjacent sample values.

A conforming Reader may choose to not implement this feature of PDF, or may use any specific implementation of interpolation that it wishes.

The default value is false.

Interpolation flag is prohibited by PDF/A compliance. false value will be used automatically when saving to PDF/A.
