\BaconQrCode\CommonBitMatrix

__construct()

__construct(integer  $width, integer|null  $height = null) 

Creates a new bit matrix with given dimensions.

Parameters

Throws

\BaconQrCode\Common\Exception\InvalidArgumentException

get()

get(integer  $x, integer  $y) : boolean

Gets the requested bit, where true means black.

Parameters

Returns

set()

set(integer  $x, integer  $y) : void

Sets the given bit to true.

Parameters

flip()

flip(integer  $x, integer  $y) : void

Flips the given bit.

Parameters

clear()

clear() : void

Clears all bits (set to false).

setRegion()

setRegion(integer  $left, integer  $top, integer  $width, integer  $height) : void

Sets a square region of the bit matrix to true.

Parameters

getRow()

getRow(integer  $y, \BaconQrCode\Common\BitArray  $row = null) : \BaconQrCode\Common\BitArray

A fast method to retrieve one row of data from the matrix as a BitArray.

Parameters

Returns

setRow()

setRow(integer  $y, \BaconQrCode\Common\BitArray  $row) : void

Sets a row of data from a BitArray.

Parameters

getEnclosingRectangle()

getEnclosingRectangle() : \SplFixedArray

This is useful in detecting the enclosing rectangle of a 'pure' barcode.

Returns

getTopLeftOnBit()

getTopLeftOnBit() : \SplFixedArray

Gets the most top left set bit.

This is useful in detecting a corner of a 'pure' barcode.

Returns

getBottomRightOnBit()

getBottomRightOnBit() : \SplFixedArray

Gets the most bottom right set bit.

This is useful in detecting a corner of a 'pure' barcode.

Returns

getWidth()

getWidth() : integer

Gets the width of the matrix,

Returns

getHeight()

getHeight() : integer

Gets the height of the matrix.
