[−][src]Struct bardecoder::decode::QRDecoder

pub struct QRDecoder {}

Decode a QR code into a resulting String

This decoder will, in order:

  • Determine QR Format information
  • Extract the interleaved blocks of codewords
  • Perform error correction
  • Decode the blocks into a String

Optimisation

The error correction process can be relatively expensive. This decoder has a fast detection of the existence of errors, allowing to bypass the correction altogether if none exist. Users of this library are encouraged to provide high quality fault-free images, speeding up the decoding process by not having to correct errors.

Methods
