Hi Vipin

Did you ever come right with Tesseract 4 under C#? I've been using version 
3 but would like to move to version 4.

I assume you mean the charlesw/tesseract wrapper on Github.  Questions are 
more directly answered there.  What steps did you perform and what is the 
symptom?

Hi Vipin
I didn't get much further with that wrapper I'm afraid. In the end, I went 
for building tesseract from the C++ source code.

Hi James, my apologies to hit you up so randomly, but I had no ther options 
left. Ive been trying to get Tesseract 4 working using tesseract.net 
wrapper following the wiki here

[tesseract-ocr] Re: I Need help getting Tesseract 4.0 C# .Net Wrapper working please!

[James Q]

You are correct, the runtime version is 140. That doesn't appear to be my 
problem though as x64 Dependency Walker finds this DLL. It fails to find 
several DLLs though which begin 'API-MS-WIN-CORE...'. I would have expected 
these to be present by way of the Win10 SDK but they are not. I tried 
Charles Weld's newer version from Git and got the same issues with that but 
I haven't tried the trace feature in Charles' version yet so will try that.

Thanks for responding to this - much appreciated.

[THintz]

I built those DLLs with VS 2017.  I think the run-time lib version is 140.

There are 3 main reasons the libs fail to load.

1. The DLLs are in the wrong folders.  The correct folders are:
 The .Net wrapper DLL assembly is placed in the exact same folder you 
run your app from, and the other 2 are placed in a folder x86 or x64 
located in the app's folder.  The DLLs I created are only x64.

2. You are missing a dependency.  
See https://github.com/charlesw/tesseract/issues/363 for examples tracing 
this.  If you must resort to procmon to figure this out then you need to be 
prepared to read tea leaves.

3. The wrong .Net wrapper is used.  Mr. Weld's wrapper has a trace feature 
that enables you see mismatch between the wrapper and the DLLs.  A mismatch 
occurs when the wrapper tries to bind to the public interface of Leptonica 
and the two differ.

The DLLs I created have been superseded in a branch of charlesw/tesseract 
on github.  There is actually not much functional difference between the 
two, at this time, but you might find it easier to work with the newer 
branch.

[tesseract-ocr] Re: I Need help getting Tesseract 4.0 C# .Net Wrapper working please!

[James Q]

Thanks for the reply, In my project I have tried all 3 DLLs in all 
potential folders as follows:

D:\csharp\repos\cwtess4
|__ D:\csharp\repos\cwtess4\cwtess4
|__ liblept1741.dll
|__ libtesseract400.dll
|__ Tesseract.dll
|__ D:\csharp\repos\cwtess4\cwtess4\bin
|__ liblept1741.dll
|__ libtesseract400.dll
|__ Tesseract.dll
|__ D:\csharp\repos\cwtess4\cwtess4\bin\x64
|__ liblept1741.dll
|__ libtesseract400.dll
|__ Tesseract.dll
|__ D:\csharp\repos\cwtess4\cwtess4\bin\x64\Release
|__ liblept1741.dll
|__ libtesseract400.dll
|__ Tesseract.dll
|__ D:\csharp\repos\cwtess4\cwtess4\bin\x64\Debug
|__ liblept1741.dll
|__ libtesseract400.dll
|__ Tesseract.dll

This exception appears at runtime:
System.Reflection.TargetInvocationException: 'Exception has been thrown by 
the target of an invocation.'
Inner Exception
DllNotFoundException: Failed to find library "liblept1741.dll" for platform 
x64.

I see on the page you mention that a common reason might be "The Visual 
Studio 2015 C++ runtime" not being installed, but I am using Visual Studio 
2017 which doesn't allow me to install the earlier version of the runtime.

I don't think the code has been updated to show which options are supported
in 4.00alpha.

You can see https://github.com/tesseract-ocr/tesseract/issues/751 regarding
whitelist issue.

Re: [tesseract-ocr] Re: I Need help getting Tesseract 4.0 C# .Net Wrapper working please!

[James Q]

Thanks for the reply ShreeDevi, I haven't found much in the way of 
documentation to say which options are supported in 4.0alpha compared to 
3.0x. I ran "tesseract.exe --print-parameters" and both 
"tessedit_char_whitelist" / "tessedit_char_blacklist" were still in the 
list. I therefore assumed they were still supported. 

Could you please let me know how to find out which options are still 
supported in 4.0?

Is there an alternative option to tell tesseract to exclude certain 
characters (in my case I have a number format which has numbers and letters 
but never capital O).

Thanks
James

 If anyone has this working I would greatly appreciate any advice.

[tesseract-ocr] Re: I Need help getting Tesseract 4.0 C# .Net Wrapper working please!

[James Q]

By the way I do have the Tesseract.net nuget package working ( 
https://www.nuget.org/packages/tesseract.net/ ), but have 2 issues with 
this:
1.) I need to write a separate Bitmap -> Pix converter in C#
2.) I haven't yet got whitelists/blacklists working

Neither of these were issues with the tesseract 3 Charles Weld wrapper, 
hence my reason for trying to get the tdhintz one working (as this is based 
on Charles Weld's 3 wrapper).
Thanks
James
