Spire.Barcode is a professional barcode library specially designed for .NET developers (C#, VB.NET, ASP.NET, .NET Core) and Java developers (J2SE and J2EE) to generate, read and scan 1D & 2D barcodes.

I have an image with two QR codes. The Barcode Reader reads only one QR code in the case when they are located in a row (pixel to pixel) on the image. But it reads correctly if I shift one of the barcodes up or down even for one pixel.
I attached two images with equal barcodes. For one image reader returns one result, for the other - two.

Can you help me with this?

Hello,

Thanks for your contact.
I did notice the behavior you described with our free version. Sorry for that and we have no plan to maintain the free version at present. Please upgrade to our commercial version (Spire.BarCode for .NET Version:2.3) which works Ok and will return two data while scanning "barcode_inline.png" to try again. If there is any question, welcome to write back.

Sincerely,
Nina
