Hi,

I want to extract text from PDF in C# asp.net. I am using this code as following link ::

Link:: http://www.codeproject.com/KB/cs/PDFToText.aspx

But this code is not working properly. The main problem is that when i get output file they have no that content which are in Inputfile.

Is there any way to resolve this problem ?

Please help me.

Thanks in advance.

The LEADTOOLS SDK can also extract text from PDF files. They have a code snippet available showing how to perform this. This functions for both vector PDFs in which the SVG information is extracted, or raster PDFs in which an Optical Character Recognition is performed.

The SDK is available for a 60-day evaluation period on the official site.

There is a C# library called SharpPDF and I think one called iTextSharp. iTextSharp can be used to read a pdf file

PdfReader reader = new PdfReader("In.PDF");

Then extract the images, not sure about how to do the text, but it should point you in the right direction:http://www.vbforums.com/showthread.php?t=530736
