Struct QRExtractor 

Source 
pub struct QRExtractor {}
Expand description

Extract QR Data from a preprocessed image

If the version of the QR is higher than 1, this extractor will first try to find the bottom left-most alignment pattern and adjust for any perspective skewing.

Data is extracted by sampling the center pixel of the estimated module locations. These are determined by dividing each row and column into equal parts.
