Public API changes and backwards compatibility

Pdf417 recognition performance

Pdf417 barcode recognition performance has been enhanced, with better results on mobile devices and in document processing scenarios.

from aspose.barcode.barcoderecognition import BarCodeReader, DecodeType, MultyDecodeType

reader = BarCodeReader("Pdf417.png", MultyDecodeType(
                [
                    DecodeType.PDF417,
                    DecodeType.CompactPdf417,
                ]
            ))
for result in reader.read_bar_codes():
    print(result.code_text)

Han Xin code recognition performance

Han Xin code recognition performance has been refined, leading to more consistent decoding.

from aspose.barcode.barcoderecognition import BarCodeReader, DecodeType

reader = BarCodeReader("HanXinCode.png", DecodeType.HAN_XIN)
for result in reader.read_bar_codes():
    print(result.code_text)

Aztec Code recognition performance

Aztec Code barcode recognition performance has been enhanced, with better results on mobile devices and in document processing scenarios.

from aspose.barcode.barcoderecognition import BarCodeReader, DecodeType

reader = BarCodeReader("Aztec.png", DecodeType.AZTEC)
for result in reader.read_bar_codes():
    print(result.code_text)

GS1 Composite Barcode recognition process

GS1 Composite Barcode recognition process has been updated to eliminate delays when using DecodeType.Types2D.

from aspose.barcode.generation import BarcodeGenerator, EncodeTypes, TwoDComponentType, CodeLocation
from aspose.barcode.barcoderecognition import BarCodeReader, DecodeType

gen = BarcodeGenerator(EncodeTypes.GS1_COMPOSITE_BAR, "(01)13112345678906|(17)010615(10)A123456")
gen.parameters.barcode.gs1_composite_bar.linear_component_type = EncodeTypes.GS1_CODE_128
gen.parameters.barcode.gs1_composite_bar.two_d_component_type = TwoDComponentType.CC_C
gen.parameters.barcode.gs1_composite_bar.is_allow_only_gs1_encoding = True
gen.parameters.barcode.code_text_parameters.location = CodeLocation.NONE

reader = BarCodeReader(gen.generate_bar_code_image(), DecodeType.GS1_COMPOSITE_BAR)
for result in reader.read_bar_codes():
    print(result.code_text)

Inverted Barcodes Recognition Performance

The recognition performance for inverted barcodes, where foreground and background colors are swapped, has been significantly improved. These enhancements provide more reliable decoding:

on mobile devices under variable lighting conditions,
in scanned documents that contain negative or inverted images,
in high-contrast PDF files and document-processing workflows. The feature can be enabled via the InverseImage quality setting:

from aspose.barcode.generation import BarcodeGenerator, EncodeTypes
from aspose.barcode.barcoderecognition import BarCodeReader, DecodeType, InverseImageMode
from aspose.pydrawing import Color

gen = BarcodeGenerator(EncodeTypes.DATA_MATRIX, "0126789ABCDEFabcdef")
gen.parameters.barcode.bar_color = Color.white
gen.parameters.back_color = Color.black

reader = BarCodeReader(gen.generate_bar_code_image(), DecodeType.DATA_MATRIX)
reader.quality_settings.inverse_image = InverseImageMode.ENABLED

for result in reader.read_bar_codes():
    print(result.code_text)

AAMVA DL/ID Card Barcode Support

Support for encoding and decoding AAMVA-compliant Driver License and Identification Card barcodes has been added through the new USADriveIdCodetext class. This enables working with the structured data embedded in U.S. Driver License PDF417 barcodes, including:

standardized mandatory fields,
optional AAMVA elements,
jurisdiction-specific subfiles,
automatic subfile construction (types, offsets, lengths),
full parsing and reconstruction of the codetext. The implementation follows the AAMVA DL/ID Card Design Standard (2025).

Specification: AAMVA DL/ID Card Design Standard (2025)
