Struct LineScan

Source

pub struct LineScan {}

Expand description

Scan a prepared image for QR Codes

The general idea of this method is as follows:

Scan line by line horizontally for possible QR Finder patterns (the three squares)
If a possible pattern is found, check vertically and diagonally to confirm it is indeed a pattern
Try to find combinations of three patterns that are perpendicular and with similar distance that form a complete QR Code
