We read PDF147 barcode on US Driver's License, but experiencing an issue with correct orientation detection. I have set Autodetect page orientation everywhere, but it still does not recognize it.

See attached examples. Vertical image is not recognized.

Thanks for your help in advance!

The reason of the issue is not an orientation, but the resolution of the image. The horizontal orientation image you have provided has no resolution specified, so FC detects resolution based on text size and it turns out correct, so the barcode is detected.

But the resolution of the "vertical" image is 72 dpi and is way lower the recommended for FC (300dpi). The barcode is too large for the image, so the detection fails.

Attached you will find your image converted to 300dpi resolution. The barcode is fully recognizable.

Hello Alexey,

Thanks for your response and I'm sorry for the delayed answer.

I have tried image you have attached, but it didn't work. Still does not recognize it unless image is horizontal.

If you have tested it by creating FlexiLayout, could you please share it or let me know what and where configuration you set?

Thanks for your help!
