Hi,
Thanks for considering Aspose.
I was able to reproduce the problem and informed the developers about the recognition problem. I have also logged it in our bug tracking system (ID: 11546). We will notify you when there is any progress about the issue or it gets resolved. Sorry for the inconvenience.
any news on this one?
We got the same problem using v 3.0.0.0.
This is quite critical since we are getting bad feedback from our clients...
I finally used an other SDK which works perfectly for my needs.

I am having what appears to be a similar problem with a scan of a PDF417 barcode. I had been using Aspose BarcodeRecognition 4.6, so I tried using the 5.4 DLL from here: http://www.aspose.com/community/files/51/.net-components/aspose.barcode-for-.net/default.aspx

Hi.
We have a problem. We have to read a lot of printed sheets containing PDF417 barcodes that were generated with version 5.4 of Aspose.Barcode and that are giving us reading problems.
We do not have the original data for that information.
The question we want to ask you is if there is any way to read those PDF417s.
I beg you for a quick reply.
Thanks in advance
@RubenL,
You may create a new thread as this is quite old thread and it is better for proper follow up. You may try the scenario with the latest version as we do not test issues with the older versions and as per policy issues are resolved in the latest versions only.
If your issue is not resolved with the latest version, share a runnable console application which is used to create the printed sheet in question, output printed sheets and the code to read these sheets. Also share the details (along with images if any) of the problem which you are facing. We will reproduce the issue here and share our feedback accordingly.
@ahsaniqbalsidiqui,
Thanks for your quick response.
Before opening a new thread, I will tell you what we have tested and tell me if I should open the new thread or nothing can be done for this case.
We generate PDF417 barcodes with version 5.4. We have tried to read them with the latest version of Aspose.Barcode and also with 5.4.
In both cases the reading has failed.
The only option we can think of is a modified version of the barcode reader that, knowing what the problem is, assumes that the last stop bar is missing.
I don’t know if this is possible. If you think you can help us, we open a new thread.
We are a bit desperate. thanks for your help
If possible (with your current license), you can try Aspose.BarCode for .NET v5.8.0 if it fixes your issue. Please note, in Aspose.BarCode for .NET v5.8.0 we included fixes for recognizing PDF417 codes for scanned images (as the issues are discussed in this thread).
If your issue is not resolved with the suggested older version, as requested earlier, please share the image barcodes, sample code (that you are using with latest version (Aspose.BarCode for .NET 20.10) to retrieve the barcodes). We will log appropriate tickets to evaluate your issue in details and try to figure it out (if possible) soon.
I first it would be better if you start new topic with the question.
I tested pdf417 generation and recognition with 5.4 version (downloaded here) and pdf417. Everything works well.

Miss-recognition could be with low image quality. In new version the recognition quality is greatly increased but it still could have problems with recognition if image has extremely low quality. You could provide us document where you have problems and we will investigate issue (and please create new topic for this).
Hi.
Perfect. I’m going to open a new thread with this problem.
I will give you an example of an image that reads perfectly (generated with version 2.5) and another that gives an error (generated with 5.4).
If you agree, I will accompany you with the code used for reading. In reality, we read these documents with physical barcode readers but they give the same problem.
Regarding the quality of the image, the origin of the images that I am going to send you is a PDF that has one of its pages with those barcodes. I have used a conversion to jpg image from that page.
Thank you so much for everything. I will put in this thread the number assigned to the new topic.
