Aspose.BarCode for Python via Java 25.7

This page contains release notes information for Aspose.BarCode for Python via Java 25.7.

All Changes

Key	Summary	Category
BARCODENET-39312	Improve Code128 recognition performance	Enhancement
BARCODENET-39313	GS1 DataMatrix: “Incorrect value 129 for C40 Shift” error	Bug
BARCODEPYTHON-718	Implement method BarcodeResult.getCodeText(encoding)	Enhancement

Public API changes and backwards compatibility

Added parameter encoding to the function BarcodeResult.getCodeText().

Method BarcodeGenerator.setCodeText(String codeText, Charset encoding) encodes the Unicode codeText into a byte sequence using the specified encoding. UTF-8 is the most commonly used encoding. Method setCodeText(String codeText, Charset encoding, boolean insertBOM) If the encoding supports it and insertBOM is set to true, the method includes a byte order mark (BOM)

This method is intended for use with 2D barcodes only (e.g., Aztec, QR, DataMatrix, PDF417, MaxiCode, DotCode, HanXin, RectMicroQR, etc.). It enables manual encoding of Unicode text using national or special encodings; however, this method is considered obsolete in modern applications. For modern use cases, ECI encoding is recommended for Unicode data.

Using this method with 1D barcodes, GS1-compliant barcodes (including 2D), or HIBC barcodes (including 2D) is not supported by the corresponding barcode standards and may lead to unpredictable results.

#Encode DataMatrix text using Shift-JIS (Japanese encoding)
generator = BarcodeGenerator(Generation.EncodeTypes.DATA_MATRIX, None)
generator.setCodeText("車種名", "Shift-JIS")
image_path = os.path.join(self.folder, "barcode1.png")
generator.save(image_path, BarCodeImageFormat.PNG)
reader = Recognition.BarCodeReader(image_path, None, Recognition.DecodeType.DATA_MATRIX)
results = reader.readBarCodes()
for result in results:
    text = result.getCodeText("Shift-JIS")
    print("Barcode CodeText:", text)

#Encode codetext using UTF-8 with BOM
generator = BarcodeGenerator(Generation.EncodeTypes.QR, None)
generator.setCodeText("車種名", "UTF-8", True)
image_path = os.path.join(self.folder, "barcode2.png")
generator.save(image_path, BarCodeImageFormat.PNG)
reader = Recognition.BarCodeReader(image_path, None, Recognition.DecodeType.QR)
results = reader.readBarCodes()
for result in results:
    text = result.getCodeText("UTF-8")
    print("Barcode CodeText:", text)

Code 128 recognition performance

Code 128 recognition performance is improved.

generator = BarcodeGenerator(Generation.EncodeTypes.CODE_128,"ASPOSE")
image_path = os.path.join(self.folder, "barcode3.png")
generator.save(image_path, BarCodeImageFormat.PNG)
reader = Recognition.BarCodeReader(image_path, None, Recognition.DecodeType.CODE_128)
results = reader.readBarCodes()
for result in results:
    text = result.getCodeText("UTF-8")
    print("Barcode CodeText:", text)

GS1 DataMatrix generation

GS1 DataMatrix generation corresponds to GS1 DataMatrix Guideline.

generator = BarcodeGenerator(Generation.EncodeTypes.GS_1_DATA_MATRIX,"(00)057139091004349375(241)24140053(91)SkamoDoor Board 225 P2(243)035402")
image_path = os.path.join(self.folder, "barcode4.png")
generator.save(image_path, BarCodeImageFormat.PNG)
reader = Recognition.BarCodeReader(image_path, None, Recognition.DecodeType.GS_1_DATA_MATRIX)
results = reader.readBarCodes()
for result in results:
    text = result.getCodeText("UTF-8")
    print("Barcode CodeText:", text)
