Methods

__construct()

__construct(  $width,   $height = false,   $rowSize = false,   $bits = false)

Parameters

	$width
	$height
	$rowSize
	$bits

parse()

parse(  $stringRepresentation,   $setString,   $unsetString)

Parameters

	$stringRepresentation
	$setString
	$unsetString

set()

set(  $x,   $y)

Sets the given bit to true.

Parameters

	$x	; The horizontal component (i.e. which column)
	$y	; The vertical component (i.e. which row)

_unset()

_unset(  $x,   $y)

Parameters

	$x
	$y

flip()

flip(  $x,   $y)

Parameters

	$x
	$y

_xor()

_xor(  $mask)

Exclusive-or (XOR): Flip the bit in this {@code BitMatrix} if the corresponding mask bit is set.

Parameters

$mask

; XOR mask

clear()

clear()

Clears all bits (sets to false).

setRegion()

setRegion(  $left,   $top,   $width,   $height)

Sets a square region of the bit matrix to true.

Parameters

	$left	; The horizontal position to begin at (inclusive)
	$top	; The vertical position to begin at (inclusive)
	$width	; The width of the region
	$height	; The height of the region

rotate180()

rotate180()

Modifies this {@code BitMatrix} to represent the same but rotated 180 degrees

getWidth()

getWidth() : \Zxing\Common\The

Returns

\Zxing\Common\The —

width of the matrix

getRow()

getRow(  $y,   $row) : \Zxing\Common\The

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

Parameters

	$y	; The row to retrieve
	$row	; An optional caller-allocated BitArray, will be allocated if null or too small

Returns

\Zxing\Common\The —

resulting BitArray - this reference should always be used even when passing your own row

setRow()

setRow(  $y,   $row)

Parameters

	$y	; row to set
	$row	; {@link BitArray} to copy from

getEnclosingRectangle()

getEnclosingRectangle() : \Zxing\Common\{@code

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

Returns

\Zxing\Common\{@code —

left,top,width,height} enclosing rectangle of all 1 bits, or null if it is all white

getTopLeftOnBit()

getTopLeftOnBit() : \Zxing\Common\{@code

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

Returns

\Zxing\Common\{@code —

x,y} coordinate of top-left-most 1 bit, or null if it is all white

getBottomRightOnBit()

getBottomRightOnBit()

getHeight()

getHeight() : \Zxing\Common\The

Returns

\Zxing\Common\The —

height of the matrix

getRowSize()

getRowSize() : \Zxing\Common\The

Returns

\Zxing\Common\The —

row size of the matrix

equals()

equals(  $o)

Parameters

hashCode()

hashCode()

toString()

toString(  $setString = '',   $unsetString = '',   $lineSeparator = '')

Parameters

	$setString
	$unsetString
	$lineSeparator

toString_()

toString_(  $setString,   $unsetString,   $lineSeparator)

Parameters

	$setString
	$unsetString
	$lineSeparator

get()

get(  $x,   $y) : \Zxing\Common\value

Gets the requested bit, where true means black.

Parameters

	$x	; The horizontal component (i.e. which column)
	$y	; The vertical component (i.e. which row)

Returns

\Zxing\Common\value —

of given bit in matrix

_clone()
