BitMatrixParser class
@author Sean Owen
Constructors
- BitMatrixParser(BitMatrix _bitMatrix)
- @param bitMatrix BitMatrix to parse @throws FormatException if dimension is not >= 21 and 1 mod 4
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
mirror(
) → void - Mirror the bit matrix in order to attempt a second reading.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
readCodewords(
) → Uint8List - Reads the bits in the [BitMatrix] representing the finder pattern in the correct order in order to reconstruct the codewords bytes contained within the QR Code.
-
readFormatInformation(
) → FormatInformation - Reads format information from one of its two locations within the QR Code.
-
readVersion(
) → Version - Reads version information from one of its two locations within the QR Code.
-
remask(
) → void - Revert the mask removal done while reading the code words. The bit matrix should revert to its original state.
-
setMirror(
bool mirror) → void -
Prepare the parser for a mirrored operation.
This flag has effect only on the readFormatInformation and the
readVersion. Before proceeding with readCodewords the
mirrormethod should be called. -
toString(
) → String -
A string representation of this object.

Operators
-
operator ==(
Object other) → bool -
The equality operator.
