Cannot read datamatrix barcode


Attached are a few samples with small but clear datamatrix barcodes on the right. With another barcode engine I have no problem reading these but with Aspose Barcode I don’t seem able to. Do I need any specific settings in order to recognize these?

Best Regards
Hi Johan,

Thank you for your inquiry and sharing samples.

We have investigated the issue at our end. We are facing issue while reading the barcode images. Please forward us details about other barcode engines that you have used and are working. This will help us to further investigate the issue.


When uploading a tif to this online barcode reader it is giving me the correct result:


I have also tested with Kofax Capture and Kofax Transformation Modules where I think KTM is using ABBYY finereader under te hood. Both are returning the correct result.

Hi Johan,

Thank you for details.

The issue has been logged into our system with ID BARCODENET-36580. Our product team will further look into it and provide feedback. The information you shared has also been forwarded to the product team. We will update you with the feedback once available.


We have further investigated the issue. It was found that it is not a bug. It is Windows error. The TIFF file you have shared has JPEG compression (see "compressionJPEG.png"). This is an old compression format. This format is not supported on Windows 7 and above. Standard photo viewer is also not able to open this pictures (see "photoViewerError.png"). This error also exists with Windows XP. For detail, please visit the link: https://support.microsoft.com/en-us/help/885938/tiff-image-files-that-are-compressed-in-the-jpeg-format-cannot-be-corr.

It is proposed that you may use other compression like LZW. Please try the solution at your end and update us with your feedback.
