public class OptimizationOptions

Constructors

Name	Description
OptimizationOptions()	The default constructor.

Properties

Name	Description
AllowReusePageContent { get; set; }	If true page contents will be reused when document is optimized for equal pages.
CompressObjects { get; set; }	If this flag is set to true, Pdf objects will be packed into Objest Streams and compressed to reduce pdf file size.
ImageCompressionOptions { get; }	Set of options which describe will images in the document be compressed and parameters of the compression.

This allows to decrease document size in some cases (for example, when same document was concatenedted multiple times).
MaxResoultion { get; set; }	Specifies maximum resolution of images. If image has higher resolition it will be scaled
RemovePrivateInfo { get; set; }	Remove private information (page piece info).
RemoveUnusedObjects { get; set; }	If this flag is set to true, all document objects will be checked and unused objects (i.e. objects which does not have any reference) are removed from document.

UnembedFonts { get; set; }	Make fonts not embedded if set to true.

Methods

Name	Description
static All()	Creates optimization strategy will all options activated. Please note that activated only options which does not change any functionality of the document. I.e. image compressing and fonts unembedding will not enabled (and can be embedded manually).
