Function Documentation

scan()

ScanResult Prison::ImageScanner::scan ( const QImage & image, Format::BarcodeFormats formats = {} )

nodiscard

Scan image for a barcode.

This method is synchronous and expensive. For use in the main thread running this on a secondary thread is strongly recommended when processing larger images.

QtConcurrent::run([&img]() { return ImageScanner::scan(img); }).then([](const ScanResult &result) {
  ...
});

Parameters

image	The image to scan for barcodes, in any format.
formats	The barcode formats to look for. By default all supported formats are searched, limiting this improves performance and can improve result quality.
