38f83b8: #### Bump
zxing-wasmto v3 with finer-grained barcode format detectionThis release upgrades the underlying
zxing-wasmdependency from v2 to v3, which brings more precise barcode format identification. The decoder now distinguishes sub-variants within certain symbology families, so theformatfield in detection results may return more specific values than before.Detection result
formatchangesPreviously, the decoder reported the base symbology name for all variants within a family. With this release, detection results use the specific sub-variant format for the following symbologies:
Previously returned Now returns (depending on the actual barcode) "databar""databar_omni"or"databar_stacked""databar_expanded""databar_expanded"or"databar_expanded_stacked""code_39""code_39","code_39_extended","code_32", or"pzn"Note: If your code matches on exact
formatvalues (e.g.,result.format === "databar"), you may need to update it to account for the new sub-variant names. The original base format names ("databar","code_39", etc.) are still valid as input hints in theformatsoption of theBarcodeDetectorconstructor, but"databar"will no longer appear in detection output."databar_expanded"and"code_39"can still appear in output when the detected barcode is the base variant.New supported formats
The following format names are now accepted in
BarcodeDetectorOptions.formatsand may appear in detection results:"code_39_extended","code_32","pzn"— Code 39 sub-variants"databar_omni","databar_stacked","databar_expanded_stacked"— DataBar sub-variants
The following format names are now accepted in
BarcodeDetectorOptions.formatsas input hints (they do not currently appear in detection output, but requesting them may filter detection to the appropriate symbology family):"aztec_code","aztec_rune"— Aztec sub-variants"code_39_standard"— Code 39 standard variant"databar_stacked_omni"— DataBar Stacked Omni variant"ean_upc","isbn"— EAN/UPC family"itf_14"— ITF sub-variant"compact_pdf417"— PDF417 sub-variant"qr_code_model_1","qr_code_model_2"— QR Code sub-variants"other_barcode"— catch-all for unclassified formats
New shorthand formats
Three new shorthand (meta) formats can be used in the
formatsoption:"gs1_codes"— all GS1-compatible barcode formats"retail_codes"— all retail barcode formats (EAN, UPC, DataBar, etc.)"industrial_codes"— all industrial barcode formats (Code 39, Code 128, ITF, etc.)
