SubsetFonts Property

Summary

Enables or disables font sub-setting in the output PDF file.

Syntax

C++/CLI

Java

Python

public bool SubsetFonts { get; set; }

public boolean getSubsetFonts(); 
public void setSubsetFonts( 
   boolean booleanValue 
);

public: 
property bool SubsetFonts { 
   bool get(); 
   void set (    bool ); 
}

SubsetFonts # get and set (PDFOptimizerOptions)

Property Value

If true, enables font subsetting. If false, sub-setting is not enabled.

Remarks

Font sub-setting embeds only those glyphs that are used in a document, instead of the entire font.
