Here is part of Delphi code

// ttt.pbm  - image for OCR (withh TFreeBitmap JPG can be converted to PBM or useing djpeg.exe)
// ttt.txt - result of OCR
procedure TOIBCaptchaKiller.Do_OCR;
var
  StartupInfo : TStartupInfo;
  ProcessInfo : TProcessInformation;
  Res:boolean;
  cmdLine:array[0..512] of char;
  lpExitCode: DWORD;
begin
  FillChar (StartupInfo, SizeOf(StartupInfo), 0);
  StartupInfo.cb := SizeOf(StartupInfo);
  StartupInfo.wShowWindow := SW_SHOWNORMAL;//SW_HIDE
  if  CreateProcess (nil,Pchar('gocr -i ttt.pbm -o ttt.txt'),nil,nil,FALSE, 0,nil,nil, StartupInfo, ProcessInfo) then begin

  GetExitCodeProcess(ProcessInfo.hProcess, lpExitCode);

      while lpExitCode = STILL_ACTIVE do begin         // sve dok se test applikacija ne ugasi nejdi nikud
        sleep(100);
        Application.ProcessMessages;
        GetExitCodeProcess(ProcessInfo.hProcess, lpExitCode);
      end;

    CloseHandle(ProcessInfo.hProcess);
    CloseHandle(ProcessInfo.hThread);

    end;
end;

Hi,
I'll post delphi code shortly but for now try this.

This is content of test.cmd file

rem begin
 djpeg -grayscale -pnm YourPictureName.jpg YourPictureName.pnm
 gocr -i YourPictureName.pnm -o YourExtractedText.txt
rem end

test.cmd, djpeg.exe, gocr.exe, YourPictureName.jpg are together in the same directory.

With this You can test if this method satisfies Your needs.]]> Mon, 08 Feb 2010 08:23:07 +0000 http://www.quickpdf.org/forum/extract-text_topic1326_post6125.html#6125 <![CDATA[extract text : hello Can you tell me how can...]]> http://www.quickpdf.org/forum/extract-text_topic1326_post6118.html#6118 Author: kavaler

Hi,
Try this
   http://jocr.sourceforge.net/index.html

It's free and results for me were satisfactory.
If the document is scanned well and have "normal" fonts maybe this will be enough.

If You need working example just ask.

Hi Tom!

There's a better (less expensive) method...
The delphi-solution from kavaler and an additional OmniPage Pro ;-)

Cheers, Ingo

Be aware that stand alone products, like OmniPage, are not redistributable.  That means if you are just doing this for your own use then they will work fine. 
 
If, however, you are creating a program for others you'll need to obtain a SDK that may be distributed with your product.  The SDK's are quite abit more expensive.  You would be looking at prices that range between $400 and $3000.

Google is your friend... ;)

OmniPage Professional is a standalone product. You can configure it to grab files from a specified folder and output the convertet files to another. Then you can work with those resulting files in Delphi.

If I were you, I would buy OmniPage Professional (version is available for around 100$ on the net). It is able to recognize the text in scanned documents and convert them to searchable pdf files or to text files.
