public void setDisableCieColors(boolean value)
DisableCieColors # get and set (CodecsPdfLoadOptions)
Value | Description |
---|---|
true | To disable the use of CIE colors. |
false | To enable the use of CIE colors. false is the default value. |
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.
