Property UseEngineInstanceOptions As Boolean

Visual Basic (Usage)	Copy Code
Dim instance As IOcrDocument Dim value As Boolean   instance.UseEngineInstanceOptions = value   value = instance.UseEngineInstanceOptions

bool UseEngineInstanceOptions {get; set;}

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 Leadtools.Forms.Ocr.IOcrDocument.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
