Img2QR

---

Overview

Img2QR is a command-line tool designed to convert image files into QR codes. This utility takes image files from the current directory, converts them into base64-encoded strings, and then encodes these base64 strings into QR codes. The resulting QR code images are saved in the same directory, providing a convenient way to encode and distribute image data via QR codes.

Features

• Directory Scanning: Automatically scans the current directory for image files with extensions .jpg, .jpeg, and .png.
• Base64 Encoding: Converts each image file into a base64-encoded string.
• QR Code Generation: Encodes the base64 string into a QR code.
• Customizable Output: Allows customization of QR code dimensions (width and height) and colors via command-line flags.
• Batch Processing: Processes all supported image files in the specified directory.

Usage

To use the utility, compile the Go program and run the executable with the desired flags.

Compiling the Program

go build -o img2qr main.go

Running the Executable

./img2qr -width 512 -height 512 -color green

Command-Line Flags

• -width: Specifies the width of the QR code (default: 256 pixels).
• -height: Specifies the height of the QR code (default: 256 pixels).
• -color: Specifies the color of the QR code. Options are black (default), green, red, and blue.

Example

./img2qr -width 512 -height 512 -color red

This command will scan the ./images directory for image files, convert each image to a base64 string, generate a QR code of size 512x512 pixels for each base64 string, with the QR code color set to red, and save the QR codes in the same directory.
