Generate a Code-128 Barcode in Python

from spire.barcode import *

# Function to write all bytes to a file
def WriteAllBytes(fname: str, data):
    with open(fname, "wb") as fp:
        fp.write(data)
    fp.close()

# Create an instance of BarcodeSettings
barcodeSettings = BarcodeSettings()

# Set the type of barcode to Code128
barcodeSettings.Type = BarCodeType.Code128

# Set the data for the barcode
barcodeSettings.Data = "12345"

# Set the Code128SetMode type of barcode to Auto
barcodeSettings.Code128SetMode = Code128SetMode.Auto

# Create an instance of BarCodeGenerator with the specified settings
barCodeGenerator = BarCodeGenerator(barcodeSettings)

# Generate the image for the barcode
barcodeimage = barCodeGenerator.GenerateImage()

# Write the PNG image to disk
WriteAllBytes("Code128.png", barcodeimage)

Generate QR Code with a Logo Image in Python

from spire.barcode import *

# Function to write all bytes to a file
def WriteAllBytes(fname:str,data):
    fp = open(fname,"wb")
    fp.write(data)
    fp.close()

# Initialize a new instance of BarcodeSettings
barcodeSettings = BarcodeSettings()

# Set the barcode type to QR Code
barcodeSettings.Type = BarCodeType.QRCode

# Specify the background color as WhiteSmoke
barcodeSettings.BackColor = Color.get_WhiteSmoke()

# Set the QR Code data mode to Byte
barcodeSettings.QRCodeDataMode = QRCodeDataMode.Byte

# Choose the error correction level (ECL) as M
barcodeSettings.QRCodeECL = QRCodeECL.M

# Set whether to display text at the bottom of the barcode
barcodeSettings.ShowTextOnBottom = True

# Define the horizontal offset (not sure what this does exactly)
barcodeSettings.X = 3

# Store the data to be encoded in variables and set it on the settings
data = "ABC 123456789"
barcodeSettings.Data2D = data
barcodeSettings.Data = data

# Add a logo image to the QR Code
barcodeSettings.SetQRCodeLogoImage("data/Logo.png")

# Create a new instance of BarCodeGenerator using the provided settings
barCodeGenerator = BarCodeGenerator(barcodeSettings)

# Generate the barcode image
barcodeimage = barCodeGenerator.GenerateImage()

# Write the resulting image to a file
WriteAllBytes("AddLogoImageQRCode.png", barcodeimage)

Scan a Barcode Image in Python

from spire.barcode import *

# Function to append all lines of text to a file
def AppendAllText(fname: str, text: List[str]):
    # Open the file in write mode
    fp = open(fname, "w")

    # Iterate over each line of text
    for s in text:
        # Write the line to the file
        fp.write(s)

    # Close the file handle
    fp.close()

# Use BarcodeScanner class to scan a file using the specified barcode type 
strCode = BarcodeScanner.ScanFileWithBarCodeType("data/QRCode.png",BarCodeType.QRCode)

# Append all scanned strings to a text file
AppendAllText("ScanFileWithBarCodeType.txt",strCode)
