Introduction

The goal of this project is to demonstrate how to use Go with chromedp to automate web browsing and screenshot capture. Additionally, it uses the go-qrcode library to generate a QR code for the webpage URL and overlays both the QR code and the URL text on the captured screenshot.

Features

  • Capture a screenshot of a webpage using headless Chrome.
  • Generate a QR code for a specified URL.
  • Overlay the QR code and URL text on the screenshot.
  • Save the final composite image as a PNG file.

Requirements

To run this program, you will need:

  • Go 1.16 or later
  • Headless Chrome
  • Fonts that support Truetype, like DejaVu Sans or any other Truetype font.
  • The following Go packages:
    • github.com/chromedp/chromedp
    • github.com/golang/freetype
    • github.com/golang/freetype/truetype
    • github.com/skip2/go-qrcode
    • golang.org/x/image/font

Installation

  1. Install Go: Ensure you have Go installed on your machine. You can download it from the official Go website.

  2. Install Headless Chrome: If you haven't installed Chrome or Chromium yet, you can download it from here or use your package manager.

  3. Get the required Go packages: Run the following command to install the necessary Go packages:

    go get -u github.com/chromedp/chromedp
go get -u github.com/golang/freetype
go get -u github.com/skip2/go-qrcode
go get -u golang.org/x/image/font

  4. Clone the repository:

  git clone https://github.com/logerror/url2img.git
  cd url2img
  1. Build the program:
  go build -o url2img main.go

Usage

Run the compiled binary with:

./url2img <Url> <Image Path: eg: screenshot_with_qrcode.png>

example:  ./url2img https://logerror.github.io screenshot_with_qrcode.png

The program will capture a screenshot of the specified URL, generate a QR code, overlay the QR code and the URL text on the screenshot, and save the final image as screenshot_with_qrcode.png.
