   ByVal dib As IntPtr, _
   ByVal callback As OcrProgressCallback _
) As IOcrPage
Visual Basic (Usage)Copy Code
Dim instance As IOcrPageCollection
Dim pageIndex As Integer
Dim dib As IntPtr
Dim callback As OcrProgressCallback
Dim value As IOcrPage
 
value = instance.InsertDib(pageIndex, dib, callback)
C# 
IOcrPage InsertDib( 
   int pageIndex,
   IntPtr dib,
   OcrProgressCallback callback
)
C++/CLI 
IOcrPage^ InsertDib( 
   int pageIndex,
   IntPtr dib,
   OcrProgressCallback^ callback
) 

Parameters

pageIndex
The zero-based index at which dib should be inserted.
dib
An unmanaged pointer to the DIB (device-independent bitmap).
callback
Optional callback to show operation progress.

Return Value

The IOcrPage object that define the newly inserted page.

Example

For an example on how to insert a page, refer to InsertPage. For an example on how to add pages from a DIB, refer to AddDib.

Remarks

This method will insert a device independent bitmap (DIB) stored in an unmanaged memory pointer to the OCR document.

You can use the OcrProgressCallback to show the operation progress or to abort it. For more information and an example, refer to OcrProgressCallback.

The LEADTOOLS OCR engine supports pages of dots per inch (DPI) values of 150 and greater. If you try to add a page with a DPI of less than 150 then the engine might be able to recognize any data from this page.

Note, the LEADTOOLS Plus OCR engine does not support image size greater than A3 paper size (11.7 by 16.5 inches at 300 dpi). Attempting to add an image that has a size greater than A3 will result in an error. For document of size greater than the maximum allowed, you must first resize the image before adding it to the LEADTOOLS Plus OCR engine. The Professional and Advantage engines do not have a restriction on the image size.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7
