Method Read

Reads every barcode of a decoded image, in the order the reader found them. An image without a barcode returns an empty list.

public IReadOnlyList<BarcodeDetection> Read(ImageBuffer image, CancellationToken cancellationToken = default)

IReadOnlyList<BarcodeDetection>: The barcodes found, positioned in the image's pixels.

Reads every barcode of an image file (its first page for a multi-page TIFF).

public IReadOnlyList<BarcodeDetection> Read(string imagePath, CancellationToken cancellationToken = default)

imagePath string: The image file (PNG, JPEG, TIFF, BMP, WebP...). For a PDF, use ReadPages(string, string, int, string, CancellationToken).
cancellationToken CancellationToken: Cancels the read before it starts.

Reads every barcode of one page of a document (PDF, image, multi-page TIFF...).

public IReadOnlyList<BarcodeDetection> Read(Attachment source, int pageIndex, int dpi = 200, CancellationToken cancellationToken = default)

source Attachment: The document.
pageIndex int: The zero-based page index.
dpi int: The resolution a PDF or other vector page is rendered at; image pages are read at their own resolution.
cancellationToken CancellationToken: Cancels the read.

IReadOnlyList<BarcodeDetection>: The barcodes found, with their PageIndex and PageRegion, in reading order.
