Properties summary
protected integer $qr_find_from_random

If false, checks all masks available, otherwise the value indicates the number of masks to be checked, mask id are random

# false
protected boolean $qr_find_best_mask

If true, estimates best mask (spec. default, but extremally slow; set to false to significant performance boost but (propably) worst quality code

# true
protected integer $qr_default_mask

Default mask used when $this->qr_find_best_mask === false

# 2
protected array $runLength

Run length

# array()
public integer $version

QR code version. The Size of QRcode is defined as version. Version is an integer value from 1 to 40. Version 1 is 2121 matrix. And 4 modules increases whenever 1 version increases. So version 40 is 177177 matrix.
