Syntax
C#
Objective-C
C++/CLI
Java
Python
public bool DisableCieColors { get; set; } 
@property (nonatomic, assign) BOOL disableCieColors; 
public boolean getDisableCieColors() 
public void setDisableCieColors(boolean value) 
public: 
property bool DisableCieColors { 
   bool get(); 
   void set (    bool ); 
} 
DisableCieColors # get and set (CodecsPdfLoadOptions) 

Property Value

Value Description
true To disable the use of CIE colors.
false To enable the use of CIE colors. false is the default value.
Remarks

The value of this property is used only when Leadtools.Pdf.Utilities.dll is used by the application. For more information, refer to Implementing PDF Features.

Disabling the use of CIE colors will result in faster loading. This options is used when loading both PDF, PostScript (PS) and Encapsulated PostScript (EPS) files.

* This option affect pdf format when UsePdfEngine is set to true to use Leadtools.Pdf.Utilities.dll, it still affects Postscript format.
