extractPureBits()

extractPureBits(\Zxing\Common\BitMatrix  $image) : mixed

This method detects a code in a "pure" image -- that is, pure monochrome image which contains only an unrotated, unskewed, image of a code, with some white border around it. This is a specialized method that works exceptionally fast in this special case.

Parameters

\Zxing\Common\BitMatrix $image

Returns

mixed —

moduleSize()

moduleSize(mixed  $leftTopBlack, \Zxing\Common\BitMatrix  $image) : mixed

Parameters

mixed $leftTopBlack
\Zxing\Common\BitMatrix $image

Returns

mixed —
