Property Value

Recomendations:
To increase recognition quality - upscale image if image contains very small barcodes (single bar or matrix cell is less than 1.5 pixel).
To increase recognition speed - downscale image if image contains large barcodes (single bar or cell is greater than 6 pixels).
Optimal single bar or matrix cell size is 3..6 pixels.

Target Platforms: .NET 8; .NET 7; .NET 6; .NET Framework 4.8, 4.7, 4.6, 4.5, 4.0, 3.5
