withInformationDensity

fun withInformationDensity(informationDensity: Int): QRCodeBuilder(source)

The level of "information density" this QRCode will support.

Defaults to 0. Meaning the minimum possible value will be computed and used.

Must be a value between 1 and 40. If this value is 0 (zero), the minimum possible value for it will be computed and used instead.

This is complex to explain, but basically the lower this value the fewer squares the QRCode have. The catch is: the fewer squares the QRCode have, the harder it'll be to read damaged/obstructed versions of it.

In short:

  • Ease of reading: Bump it as high as you want. Up to 6 is enough for a LOT of cases, even with logos.

  • Smaller size: Go with the computed value =)
