UseEngineInstanceOptions Property

bool UseEngineInstanceOptions {get; set;}

'Declaration
 
Property UseEngineInstanceOptions As Boolean

'Usage
 
Dim instance As IOcrDocument
Dim value As Boolean
 
instance.UseEngineInstanceOptions = value
 
value = instance.UseEngineInstanceOptions

bool UseEngineInstanceOptions {get; set;}

get_UseEngineInstanceOptions();
 set_UseEngineInstanceOptions(value);  

property bool UseEngineInstanceOptions {
   bool get();
   void set (    bool value);
}

Property Value

When the value of this property is true, then this IOcrDocument will copy the options from IOcrEngine.RasterCodecsInstance and IOcrEngine.DocumentWriterInstance to IOcrDocument.RasterCodecsInstance and IOcrDocument.DocumentWriterInstance before using them.

This makes it easy to change Leadtools.Codecs.RasterCodecs and and Leadtools.Forms.DocumentWriters.DocumentWriter options globally for all current and future IOcrDocument's.

If you have a requirement to use different options per IOcrDocument in the same IOcrEngine, for example, you have an IOcrDocument object that will save to PDF with Image/Text option and another to save to PDF/A. Then you can set UseEngineInstanceOptions of each document to false, then change the PDF options through DocumentWriterInstance instead of IOcrEngine.DocumentWriterInstance.

The options are copied before any of the following methods is called:

• IOcrDocument.Pages.AddPage

• IOcrDocument.Pages.AddPage

• IOcrDocument.Pages.AddPages

• IOcrDocument.Pages.InsertPage

• IOcrDocument.Pages.InsertPages

• IOcrDocument.Pages.ExportPage

• IOcrDocument.Pages.ExportPages)

• IOcrDocument.Save

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
