ARM64 support for Aspose.BarCode for .NET

suhailmahmood · October 24, 2024, 11:20am

But why would removing a package (System.Memory) which is added by another package (OpenCvSharp4) as a dependency resolve the issue of some exception being thrown by some other package (Aspose.BarCode)? Isn’t this very, very counter-intuitive? Can you please share details as to why you think removing the System.Memory package is the solution in this case? I am just trying to make sure I am not making some uneducated changes to my application, and as it stands now, I don’t understand the reasoning behind the solution that you suggested. So, please share the reasoning.

Please note, I am still unable to isolate the actual issue that I am facing in my actual app (null reference exception) that I shared in this comment. I encounter this error sporadically. I will share details if I am able to isolate this.

@suhailmahmood,

I am not sure either. Anyways, we logged it against your existing ticket into our database for thorough evaluation. We will update you once there an update on it. I guess in your provided project there was a reference existed of lower version of System.Memory. That’s why I removed it manually.

Sure, please take your time to isolate the actual issue and then provide a sample project to reproduce it on our end.

Since I am unable to isolate the issue into a demo app at this time (I am continuing to try tho), let me share some more data of the exception that I am getting.

Exception.Message: Object reference not set to an instance of an object.
Exception.HResult: -2147467261
Exception.TargetSite.DeclaringType: {Name = "BarCodeResult" FullName = "Aspose.BarCode.BarCodeRecognition.BarCodeResult"}
Exception.TargetSite.MetadataToken: 100674712
Exception.TargetSite.Module: {Aspose.BarCode.dll}
Exception.TargetSite.Name: "\u000e\u000f"

I am not entirely sure which of these properties will prove to be useful, so I will share a screenshot.

Here’s a screenshot:

We added task to add System.Memory and related libraries to nuget reference. In case of using .Net Core project the libraries are added automatically, but for .Net Framework we need fix.

alexander.gavriluk · October 24, 2024, 5:19pm

As I understand you work in 32 bit environment. The problem might be with insufficient memory, because barcode reader in some cases can use around 1 GB of memory on large images. You can decrease image to HD size before the recognition, this might help with the problem.

You can copy full StackTrace value (branch StackTrace on the left) to txt file and this might help to find possible issue.

Also you can see the memory consumption on the potential image which made crash.

suhailmahmood · October 24, 2024, 5:43pm

The images are very small (640x480) coming from the camera feed. So I doubt the memory usage would be that high for me. But I will run some tests again and collect the memory footprint info.

Sure, I will share the full stack trace.

alexander.gavriluk · October 24, 2024, 6:34pm

Additionally you can add debug code which:

before the recognition, it saves the image to memory stream (memory copy);
in case of exception it saves the memory stream to temporal file on the disk;
if no exception the memory stream is just collected by GC.

In this way we can catch bugged image.

suhailmahmood · October 25, 2024, 9:33am

@alexander.gavriluk That’s a good idea, but the problem is not with any specific image. But rather, the barcode that works most of the time sometimes causes the error. But anyway, I will try the approach you suggested.

amjad.sahi · October 25, 2024, 10:51am

@suhailmahmood,

Sure, please take your time and apply the suggested approach. Hopefully, it will be effective for the intended purpose.

I have recently started to work on my app after some time and have created a sample app that can reproduce the issue. I am attaching the project here. You have to put a license file named Aspose.BarCode.NET.lic in the executable’s directory. You can also it to the project and set it to copy to output.

Source code:
AsposeTest.7z (16.0 KB)

The basic workflow of the app is how we are using it in our main app.

How to use: launch the camera using the camera button at the top right corner. Then hold a barcode in front of the camera. You can generate one on your phone and show it to the camera.
When testing with a PDF417 on my dev machine (which is an intel x64 machine), I get the error that I previously mentioned in this thread. But if I run the app on an ARM64 device (e.g. Surface 11 Pro), I get way more errors, all coming from internal libraries. The errors are displayed right within the app for convenience. I am also sharing the logs that I got after running the app for some time. Another issue when running on ARM64 is that the UI gets all messed up from time to time. E.g. sometimes the camera button disappears, sometimes the date at the bottom disappears - all for unknown reasons. All these issues that you can see in this app happen with my actual app when run on ARM64 device.

PDF417 I was using:

The errors I collected after running the app for some time on a Surface 11 Pro (ARM64 device):

@suhailmahmood,

Thanks for providing sample project, error stack trace and other details. We have logged it with your existing ticket “BARCODENET-39146” into our database. We will evaluate it and get back to you soon.

At first Aspose.BarCode for .Net Framework 4.8 uses System.Drawing which is can be unstable in some moments.

I updated the project’s packages.config and AsposeTest.csproj files to use netstandard2.0 libraries for Aspose.BarCode.

AsposeTest_netstandard.zip (24.0 KB)

The second, as I see, there are problems with System.Windows.Media (video capturing). Aspose.BarCode even in .Net Framework 4.8 version uses only System.Drawing but not System.Windows.Media.

Also, I found problems locally because the project started to work only when I had copied dlls from "packages\OpenCvSharp4.runtime.win.4.10.0.20241108\runtimes\win-x86\native" to "AsposeTest\bin\Debug" . I think the project can have problems with OpenCvSharp runtimes (4.10.0.20241108 version) because them can use some unsupported on ARM emulation processor’s command.

Thanks for your response!

I have tried out the application and I am still getting similar errors. I collected these errors (at the bottom) after running the app for some time on a Surfact 11 Pro tablet.

Regarding having to copy the OpenCvSharp4.runtime.win DLLs from the packages folder, it is automatically copied after clean → build. But in the original project that I shared, the DLLs would be copied automatically. It is not a big problem though.

I am using the OpenCvSharp4 for video capture in my main app as part of facial recognition as well, which works just fine. That is, the same camera feed is used to do facial recognition and barcode recognition. The user can choose to turn on/off either of these features or both. The errors happen only when barcode recognition is enabled, and everything works just fine with barcode recognition disabled but facial enabled. So, it does NOT look like the issue is with OpenCvSharp4, but rather it seems there’s some kind of incompatibility issue with Aspose on ARM, which is where I need your help.

Question: Does Aspose.BarCode officially support Windows on ARM? If not officially, do you have data as to how well it works on Windows on ARM? Does it mostly work but with some known issues? Does it work poorly? I am trying to understand what we can expect and what we can’t. We already purchased Aspose.BarCode but only after integrating with our app are we seeing that there’s some serious incompatibility issues with Windows on ARM.

If you just remove Aspose.Barcode and Aspose.Drawing.Common from your application (with the code which it use them, just draw fake rectangle in center of screen with sleep(100) for recognition emulation), do you have the same issues.

The problem is strange because Aspose.Barcode and Aspose.Drawing.Common do not use System.Windows functions for drawing.

I have tried it out - no issues there after removing Aspose packages and codes.

alexander.gavriluk · January 9, 2025, 12:03am

Could you just use the AsposeTest_netstandard.zip and comment ShowBarcodeBoundingBoxes in CameraWindow.xaml.cs (I want to understand is this bug during recognition or drawing)

private async Task DetectBarcode()
{
    while (!_cts.Token.IsCancellationRequested)
    {
        try
        {
            if (!_videoCapture.Grab())
                return;

            using (var image = _videoCapture.RetrieveMat().Flip(FlipMode.Y))
            using (var stream = image.ToMemoryStream())
            {
                var results = _barcodeReader.Decode(stream);
                //ShowBarcodeBoundingBoxes(results, image.Width, image.Height);
            }
        }
        catch (Exception e)
        {
            Trace.TraceError($"Something went wrong while reading barcode: {e}");
        }

        await Task.Delay(100);
    }
}

I have commented out the line and run the app for some time, and I collected the following logs. So, looks like it wasn’t an issue in drawing the rectangles.

Having said that, I have found that if I make a x64 build of the app, all the errors suddenly go away for good. I ran the x64 build for hours and haven’t seen an error, not even once!! To me it seems that’s the resolution, but I will keep observing for some more time.

We do not test our last versions of library for 32-bit mode and support 32-bit mode as is, mostly for barcode generation which requires less memory. I think problem can be tied to memory fragmentation which inflicts most of problem in 32-bit mode (when system has enough memory but it is fragmented and system cannot provide required block as one piece).

It is good that 64-bit mode solves the problem and I do not think that we will add more support for 32-bit mode.
