I made it public. You should be able to access it now
Thanks for providing the requested information and your patience with us. We have tested with your application and looks like the culprit is below line of code:
input.Add("\Files\OCRTest.pdf", startPage:=1, pagesCount:=1)
The input document has only one page and index starts from 0. So it should be added like below:
input.Add("\Files\OCRTest.pdf", startPage:=0, pagesCount:=1)
Just by modifying like above, we were able to generate correct output.
OCRTestOCR_0.pdf (417.7 KB)
I started a new project and changed the StartPage to 0. When the app is run I get the error:
System.IO.FileNotFoundException: ‘Could not load file or assembly ‘Microsoft.ML.OnnxRuntime, Version=0.0.0.0, Culture=neutral, PublicKeyToken=f27f157f0a5b7bb6’ or one of its dependencies. The system cannot find the file specified.’
So I went to NuGet and added Microsoft.ML.OnnxRuntime version 1.20.1. Now when I run it it errors in code in NativeMethods.shared.cs. The error is:
System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.
Source=Microsoft.ML.OnnxRuntime
StackTrace:
at Microsoft.ML.OnnxRuntime.NativeMethods…cctor() in D:\a_work\1\s\csharp\src\Microsoft.ML.OnnxRuntime\NativeMethods.shared.cs:line 368
This module got loaded with the OnnxRuntime. Please advice.
Please make sure that you start a project with .NET Framework >=4.6.2. Also, please install Aspose.OCR for .NET from NuGet Package Manager because this way it will install all dependencies with correct versions. As shared earlier, we performed all these steps and did not notice any issues in our environment.
Ok. I changed the framework to 4.6.2 but it still errors. I even started a new project but get the same error. In both scenarios I added Aspose.OCR using NuGet manager. The error occurs on the code line:
Dim resultsNoStamp As List(Of RecognitionResult) = ocr.Recognize(input, settings)
Here are the details from the error:
System.NullReferenceException
** HResult=0x80004003**
** Message=Object reference not set to an instance of an object.**
** Source=Microsoft.ML.OnnxRuntime**
** StackTrace:**
** at Microsoft.ML.OnnxRuntime.NativeMethods…cctor() in D:\a_work\1\s\csharp\src\Microsoft.ML.OnnxRuntime\NativeMethods.shared.cs:line 368**
Please download a sample project at given link and test using it. You can change the path to .lic and other input/output files according to your environment and let us know if you face issues with it.
I downloaded the sample project and it error on the same line of code. The problem is in the NativeMethods.shared.cs code at line 368.
The line is:
OrtCreateEnv = (DOrtCreateEnv)Marshal.GetDelegateForFunctionPointer(api_.CreateEnv, typeof(DOrtCreateEnv));
It is strange because we tested using same application in our environment and we did not face any issues. Are you testing it in Windows? Also, is it x86 architecture only at your end? Can you please make sure that the project is configured to use x64? Please share some screenshots of the issue and full environment details for our reference so that we can proceed with the investigation.
Sorry for the delay in responding. I have been out of the office.
We have the setting as Any CPU. When I try it with x64 I get the following error:

Have you tried using same application on another machine with different environment? Because we have used and shared same application with you and it was created from scratch. We are still unable to replicate these errors in our environment. The issue apparently looks related with System Configurations. Please share your complete environment details e.g. Windows OS Name and Version so that we can further try to investigate the issue and address it accordingly.
I thought maybe the issue was I have been running the code from the development environment (on my development PC). I published to our test server and I get the following message:
Server Error in ‘/’ Application.

The issue still seems related to missing DLLs and assembly references. It is very hard to replicate it in our environment. We will certainly assist you in resolving the issue if we could replicate it somehow at our end. If possible, please share such information that could help us in reproducing the error and then address it accordingly.
