BitMatrix

Bit matrix.

Represents a 2D matrix of bits. In function arguments below, and throughout the common module, x is the column position, and y is the row position. The ordering is always x, y. The origin is at the top-left.

class BitMatrix {

int Width [@property getter];

int Height [@property getter];

int RowSize [@property getter];

BitArrayBitType[] Bits [@property getter];

this(int width);

this(int width, int height);

bool get(int x, int y);

void set(int x, int y);

void flip(int x, int y);

void clear();

void setRegion(int left, int top, int width, int height);

BitArray getRow(int y, BitArray row);

BitArray getRow(int y);

void setRow(int y, BitArray row);

int[] getEnclosingRectangle();

int[] getTopLeftOnBit();

int[] getBottomRightOnBit();

Functions

clear void clear(): Clears all bits (set to false).
flip void flip(int x, int y): Flips the given bit.
get bool get(int x, int y): Gets the requested bit, where true means black.
getBottomRightOnBit int[] getBottomRightOnBit(): Gets the most bottom right set bit.
getEnclosingRectangle int[] getEnclosingRectangle(): This is useful in detecting the enclosing rectangle of a 'pure' barcode.
getRow BitArray getRow(int y, BitArray row): A fast method to retrieve one row of data from the matrix as a BitArray.
getRow BitArray getRow(int y): Undocumented in source. Be warned that the author may not have intended to support it.
getTopLeftOnBit int[] getTopLeftOnBit(): Gets the most top left set bit.
set void set(int x, int y): Sets the given bit to true.
setRegion void setRegion(int left, int top, int width, int height): Sets a square region of the bit matrix to true.
setRow void setRow(int y, BitArray row): Sets a row of data from a BitArray.
