This document describes the JSON format understood by the sc_barcode_generator_set_options() function.

1D Symbologies

foregroundColor: 4-tuple of integers [r, g, b, a] with r, g, b and a being in the range [0, 255]
backgroundColor: 4-tuple of integers [r, g, b, a] with r, g, b and a being in the range [0, 255]

General options

foregroundColor: 4-tuple of integers [r, g, b, a] with r, g, b and a being in the range [0, 255]
backgroundColor: 4-tuple of integers [r, g, b, a] with r, g, b and a being in the range [0, 255]

QR

errorCorrectionLevel: string, may be "L" (up to 7% damage), "M" (up to 15% damage), "Q" (up to 25% damage) or "H" (up to 30% damage). Default correction level is "M".
versionNumber: positive integer, overrides desired version number. Version number is automatically chosen if not set. Barcode generation might fail if version number is too small.
Example barcode generator settings for QR code:

{
    "foregroundColor" :  [ 255, 0, 0, 255 ],
    "backgroundColor" :  [ 0, 0, 255, 255 ],
    "errorCorrectionLevel": "Q"
}
