Simplify Barcode and QR Code Reading in Golang with Dynamsoft Barcode Reader

Integrating barcode and QR code reading capabilities into your Golang applications can enhance their functionality and streamline data processing. However, implementing such functionality from scratch can be complex and time-consuming. Enter the Golang Barcode QR Code Reader, a project that provides a Golang wrapper for the Dynamsoft Barcode Reader C++ SDK. With this module, developers can effortlessly read various types of barcodes and symbols, including QR Codes, Data Matrix, PDF417, Aztec Code, and more, from images and PDF files.

Prerequisites:

• Go
• Dynamsoft Barcode Reader v9.x trial license

Supported Platforms:

• Windows
• Linux
• macOS

Testing the Module:

To ensure the module works seamlessly, follow these steps for testing on different platforms:

For Windows:

.\run_windows_test.ps1

For Linux:

./run_linux_test.sh

For macOS:

chmod +x run_mac_test.sh

sudo ./run_mac_test.sh

How to Use the Go Module

To incorporate the Golang Barcode QR Code Reader into your project, follow these simple steps:

Download the Go module:

go get github.com/yushulx/goBarcodeQrSDK

Import the package in your Go file:

import (

"github.com/yushulx/goBarcodeQrSDK"

)

Specify the dynamic library path at runtime before running Go apps.

Parameter Configuration:

For detailed parameter configuration, refer to the official documentation.

Quick Start:

Get started quickly with the Golang Barcode QR Code Reader by setting the license key and providing the path to the image file you wish to decode:

package main

import (

"fmt"

"time"

"github.com/yushulx/goBarcodeQrSDK"

)

func main() {

ret, _ := goBarcodeQrSDK.InitLicense("LICENSE-KEY")

if ret != 0 {

fmt.Printf(`initLicense("") = %d`, ret)

}

obj := goBarcodeQrSDK.CreateBarcodeReader()

obj.SetParameters("{\"ImageParameter\":{\"BarcodeFormatIds\":[\"BF_ONED\",\"BF_PDF417\",\"BF_QR_CODE\",\"BF_DATAMATRIX\"],\"BarcodeFormatIds_2\":null,\"Name\":\"sts\",\"RegionDefinitionNameArray\":[\"region0\"]},\"RegionDefinition\":{\"Bottom\":100,\"Left\":0,\"MeasuredByPercentage\":1,\"Name\":\"region0\",\"Right\":100,\"Top\":0}}")

startTime := time.Now()

code, barcodes := obj.DecodeFile("image-file")

elapsed := time.Since(startTime)

fmt.Println("DecodeFile() time cost: ", elapsed)

if code != 0 {

fmt.Printf(`DecodeFile() = %d`, code)

}

for i := 0; i < len(barcodes); i++ {

barcode := barcodes[i]

fmt.Println(barcode.Text)

fmt.Println(barcode.Format)

fmt.Println(barcode.X1)

fmt.Println(barcode.Y1)

fmt.Println(barcode.X2)

fmt.Println(barcode.Y2)

fmt.Println(barcode.X3)

fmt.Println(barcode.Y3)

fmt.Println(barcode.X4)

fmt.Println(barcode.Y4)

}

}
