IDecoderOptions Interface

Gets or sets a value indicating whether the image should be automatically rotated. Rotation is supported for 90, 180 and 270 degrees. Barcode detector sometimes fails to detect QRCode without this flag even when orientation is zero.

The list of barcode types to search when decoding. If set to null, then all available formats are searched. This can significantly reduce performance and increase false positives.

Detect multiple barcodes on the same image.

Gets or sets the list of 1-based page numbers to process when decoding barcodes. For example "1,2-5,8-", will process pages 1, 2 to 5 inclusive and 8 to the end of the document. Use "odd" or "even" for odd/even numbered pages. Use "all" to process all pages. Use 0 for the last page, -1 for the page before the last, etc. Default is to process all pages.

Gets or sets the minimum image resolution when rasterizing pages. Set to zero to automatically select the resolution.

Gets or sets a value indicating whether to search deeper into bitmaps.

Gets or sets a value indicating whether the image should be automatically inverted if no result is found in the original image.

Add the specified barcode types to the list of types considered when decoding.

Clear all possible barcode types. All barcode types will be considered when decoding. This can significantly reduce performance and increase false positives.

Gets the list of page numbers that should be decoded. Parses the Pages string to generate a list of zero-based page numbers.

Reset decoder options to their default values.
