void ExportPage( int pageIndex, string fileName, RasterImageFormat format, int bitsPerPixel )
'Declaration Overloads Sub ExportPage( _ ByVal pageIndex As Integer, _ ByVal fileName As String, _ ByVal format As RasterImageFormat, _ ByVal bitsPerPixel As Integer _ )
'Usage Dim instance As IOcrPageCollection Dim pageIndex As Integer Dim fileName As String Dim format As RasterImageFormat Dim bitsPerPixel As Integer instance.ExportPage(pageIndex, fileName, format, bitsPerPixel)

function Leadtools.Forms.Ocr.IOcrPageCollection.ExportPage(Int32,String,RasterImageFormat,Int32)( pageIndex , fileName , format , bitsPerPixel )
void ExportPage( int pageIndex, String^ fileName, RasterImageFormat format, int bitsPerPixel )
To export more than one page to a multi-page disk file, use ExportPages(int firstPageIndex, int lastPageIndex, string fileName, RasterImageFormat format, int bitsPerPixel, int firstSavePageNumber, CodecsSavePageMode pageMode).
You can export the page to any of the file formats supported by LEADTOOLS. For more information, refer to Summary of All Supported Image File Formats.
