System.IO.FileLoadException

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create new WinForms project
2. Add reference to tesseractengine3.dll
3. var x = new TesseractProcessor();

What is the expected output? What do you see instead?
Main form window

What version of the product are you using? On what operating system?
RC

Please provide any additional information below.
Thrown System.IO.FileLoadException
This exception is thrown if the file is not a valid .NET Framework assembly.

Many thanx for this library. I search for something last 2 week.

Have you tried to build engine wrapper? I ask this because I don't sure about 
assembly I provided, is compatible with your machine.

If not yet, please try to create an engine wrapper first, you can find tutorial

The tesseractenginewrapper3.dll is built for x86. You can changed tesseract 
project settings to build for Any CPU.

System.BadImageFormatException was throwed when an executable (manged code) 
built with Any CPU tried to load a dll build with x86.

Dear ducebod,
As I commented on item #9: "I don't sure about assembly I provided, is 
compatible with your machine."

So, you should install c++ ide (vs 2008), and try to do a wrapper. If you get 
problems during do it, I can support.

Good evening,

I have the exact same error at work (XP SP3 x86). At home, it works fine (Vista 
SP1 x86).
I tried recompiling the wrapper using the method described in the wiki page.
It was actually harder than the prescribed method.
First, there was a missing include (I added a comment about that in the wiki 
page).
Then, /Zi and /Gm flags were unsupported (so said VC++, I haven't developped 
C++ for almost 2 years and after this fancy adventure I guess I'm not ever 
doing that again).
Anyway, after turning /Zi to /Z7 and /Gm to /Gm-, it compiled.

But using it w/ C#.NET 4 still does not work - same error comes up.

I would gladly do anything to get this working. I recently did the mistake of 
installing Tesseract 3 which messed up Tesseract .NET 2 wrapper (there's a 
thread about this upon the Tesseract google forum) and considering this cause - 
consequence, I do not think Tesseract 2 .NET wrapper is really suitable for any 
use beside experimental ones.
I have great expectancies about your project, Mr N'Guyen, and I would like to 
add I'm very grateful to you to have such an enterprise.

Best regards,
Benjamin Neau

[GoogleCodeExporter]

Cong,

It does not fix my problem. The missing include is something I already solved.
My issue is that the assembly you provide or the ones I compiled cannot be 
loaded.

Here is the exception I get while trying to use the wrapper in a C# program:
System.IO.FileLoadException: Could not load file or assembly 'tesseractengine3, 
Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its 
dependencies. The system cannot find the file specified.

As i stated earlier in this thread:
- I tried out your sample application at work (XP SP3 x86) -> it does not work
- I tried out your sample application at home (Vista SP1 x86) -> it does work
- I recompiled the wrapper (debug)
- I tried out your sample application at work (XP SP3 x86) with my recompiled 
wrapper -> it does not work
- I tried out your sample application at home (Vista SP1 x86) with my 
recompiled wrapper -> it does not work

Thanks for your time and consideration!

Best regards,
Benjamin

@benjamin: there must be something else: I installed VS #C 2008 just because of 
tesseractengine3 and it worked (I just need to set #include as mentioned 
above). Interesting part of error message is "The system cannot find the file 
specified." Do you have leptonica library in path (leptonlib.dll and 
leptonlibd.dll)? Can you find out what file system can not find?

leptonlibd is leptonica debug library. You can find it in source code:

ractBasedOCRAnalysis/Components/leptonlibd.dll

It must be in PATH (e.g. in the same directory where is you exe and

Dear all,

Some things as belows will help me to isolate the issue easily:

- download the latest source code from tesseract-ocr: 
   - version 3.01 r552
   - using: svn checkout http://tesseract-ocr.googlecode.com/svn/trunk/ tesseract-ocr-read-only

- do all steps on wiki item: 
http://code.google.com/p/tesseractdotnet/wiki/TesseractEngineWrapper

- use tesseractengine3.dll and tessdata (tessdata folder after checking out) 
from above step for example application.

I will support if you cannot build a wrapper.

If you get error when run example application, please help me collect the 
exception information included: message and stacktrace.

- Can you pass building a wrapper with all things I noted above (use

Original comment by duce...@gmail.com on 7 Mar 2011 at 7:07

I confused in instruction how to do wrapper.
1. From tesseract-ocr SVN download tesseract sources in folder1
2. Copy and override files from "tesseractdotnet - Revision 40: 
/trunk/dotnetwrapper/TesseractEngineWrapper" into folder1
3. Open downloaded tesseract project in VS, "Add existing item" 
(tesseractenginewrapper.h and tesseractenginewrapper.cpp) into root of project
4. Change settings
5. Build
Right?

May I use Visual Studio 2010 C++ Ultimate to do that?

http://tesseract-ocr.googlecode.com/svn/trunk/tessdata (use svn checkout)but 
TesseractEngine3Wrapper_v1.0RC is still appear "Fail to initalize Tesseract

Even, with the statement : bool status = _ocrProcessor.Init(); 
status is also = "false".

Can you help me to resolve above problem?

I downloaded the latest projects source code from 
"http://tesseractdotnet.googlecode.com/svn/trunk/" and 
"http://tesseract-ocr.googlecode.com/svn/trunk/".

@duce: Yup, it's right. I want to clarify all steps here:
1. ok (v3.01 r552)
2. You have to search 3 files name to find sub folder respectively.
3. you have to open solution in folder1\vs2008\tesseract.sln -> add 2 files to 
tesseract project
4. ok
5. ok

@phamhih: TessBaseAPI provides Init() method and return the intialize status, 
not other messages. So with your message I cannot figure out problems here.

Did you use tesseract.exe (v3.01 in .\vs2008\bin.debug) command line?
If yes: are the same prblem?
else: please try it first and report the results.
Here is tesseract-ocr document:

Another question about changing settings while building wrapper:
Output File: tesseractengine3.dll - did you mean 
Linker->Output file or Browse information->Output file?
I do not know С++
I chose Linker subitem.
And after building (no errors - Build: 13 succeeded, 0 failed, 0 up-to-date, 0 
skipped ) I get tesseractengine3.dll in folder1/vs2008 folder
What to do next?

Thanks again for your help

Original comment by duce...@gmail.com on 7 Mar 2011 at 9:26

[GoogleCodeExporter]

@duce:
Yup, it's "Linker->Output file": tesseractengine3.dll (or any name if you want).

Now, add Tesseract.OCR.AppEntry into solution. And right-click on 
References->switch to Properties tab -> Choose tesseract.

Copy liptonica library to output folder of Tesseract.OCR.AppEntry project if it 
does not exist, mark this project as Startup project.

Right-click on this project -> Choose Properties -> switch to Debug tab -> 
check to "Enable unmanaged code debugging" -> it will help you to debug into 
deep c++ level.

Configure project to build for x86 platform.

Hope it succeed :)

2D/vcsetup.exe). But tesseractengine3.dll works only if VC++ 2008 is installed. 
I don't know how to make it work without it... I tried to compile dll staticly 
but it was no effect...

With C++ 2010 Express it is also working. But not with VS2010 Ultimate...

I have not reproduced the problem (System.IO.FileLoadException) on a new 
machine (OS: win7 64, IDE: vs team system 2008).

I have two scenarios:
1. Configure Application build to "Any CPU" platform 
=> throw out exception: System.BadImageFormatException

2. Configure Application build to "x86"
=> no problems here

Hello guys,

my troubles with "System.IO.FileLoadException: Error in loading 
"tesseractengine3, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null" or 
one of it dependency." seems to be solved. Zdenko helped me via email and I 
want to share with you the new facts. I have Visual Studio 2010 and Win XP with 
SP3. I try to explain it in following steps

1. I downloaded the last version of tesseract-ocr from svn 
(http://tesseract-ocr.googlecode.com/svn/trunk/). Be carefull in "Download" 
section was missing some kind of project (.vcxproj).

2. Start vs2008\tesseract.sln and automatically was converted solution from VS 
2008 to VS 2010 without errors.

3. I set tesseract project by this tutorial 
http://code.google.com/p/tesseractdotnet/wiki/TesseractEngineWrapper

4. After build of solution, I got the new tesseractengine3.dll and I replaced 
old tesseractengine3.dll in dotnetwrapper/TesseractBasedOCRAnalysis

5. dotnetwrapper example ran without exception. :-)

These steps helped me and solved my problem with System.IO.FileLoadException. 
Zdenko thanks :-)

V.
