Detailed Description

Deconvolution (image restorations) mode which defines level of image degradation. Originally deconvolution is a function which can restore image degraded (convoluted) by any natural function like blur, during obtaining image by camera. Because we cannot detect image function which corrupt the image, we have to check most well know functions like sharp or mathematical morphology.

 This sample shows how to use Deconvolution mode
 
$reader = new BarCodeReader("test.png", null, array(DecodeType::CODE_39_FULL_ASCII, DecodeType::CODE_128));
$reader->getQualitySettings()->setDeconvolution(DeconvolutionMode::SLOW);
foreach($reader->readBarCodes() as $result)
{
   print("BarCode CodeText: " . $result->getCodeText());
}

FAST

const DeconvolutionMode::FAST = 0

Enables fast deconvolution methods for high quality images.

NORMAL

const DeconvolutionMode::NORMAL = 1

Enables normal deconvolution methods for common images.

SLOW

const DeconvolutionMode::SLOW = 2

Enables slow deconvolution methods for low quality images.
