Barcode Package

The Barcode Package is a simple yet powerful library written in Golang designed to handle barcode generation and decoding. This package provides functionalities to generate a 13-number barcode string, create barcode images, and decode barcode information from images.

Features

• Generate 13-digit barcode strings
• Encode barcode strings into images
• Decode barcode images to retrieve information

Installation

To install the Barcode Package, use go get:

go get github.com/myrachanto/barcode

Usage

First, import the package in your Go file:

import "github.com/myrachanto/barcode"

Generate Barcode String

The GenerateBarCodeNumber method generates a random 13-digit barcode string.

barcodeString := barcode.GenerateBarCodeNumber()
fmt.Println("Generated Barcode String:", barcodeString)

Encode Barcode String to Image

The Encode method encodes a 13-digit barcode string into an image and saves it as a PNG file.

barcodeString := barcode.GenerateBarCodeNumber()
err := barcode.Encode(barcodeString, "barcode_image")
if err != nil {
    // handle error
    fmt.Println("Error:", err)
} else {
    fmt.Println("Barcode image created successfully")
}

Decode Barcode Image

The Decode method reads a barcode image and returns the encoded information.

decodedString, err := barcode.Decode("barcode_image")
if err != nil {
    // handle error
    fmt.Println("Error:", err)
} else {
    fmt.Println("Decoded Barcode String:", decodedString)
}

Methods

GenerateBarCodeNumber

Generates a random 13-digit barcode string.

Signature:

func GenerateBarCodeNumber() string

Encode

Encodes a 13-digit barcode string into an image and saves it as a PNG file.

Signature:

func Encode(msg, filename string) error

Parameters:

• msg (string): The 13-digit barcode string to encode.
• filename (string): The name of the file (without extension) to save the barcode image.

Returns:

• error: An error if the encoding or file creation fails, otherwise nil.

Decode

Reads a barcode image and decodes it into a string.

Signature:

func Decode(filename string) (string, error)

Parameters:

• filename (string): The name of the file (without extension) to read the barcode image from.

Returns:

• string: The decoded barcode string.
• error: An error if the decoding or file reading fails, otherwise nil.
