SVG to PNG

A Rust CLI tool that watches a folder for .svg file changes and automatically converts them to .png files using the resvg rendering engine.

Features

• File Watching: Monitors a specified directory for new or modified SVG files.
• Automatic Conversion: Instantly converts detected SVGs to PNG format.
• Batch Processing: Optional flag to convert all existing SVGs on startup.
• Cross-Platform: Works on Windows, macOS, and Linux.

Installation

Ensure you have Rust installed. Then, clone the repository and build the project:

git clone <repository-url>
cd svg-to-png
cargo build --release

Usage

Run the tool using cargo run or the built binary.

# Basic usage (watches current directory, outputs to ./out)
cargo run

# Specify input and output directories
cargo run -- --input ./svgs --output ./pngs

# Convert existing files on startup
cargo run -- --input ./svgs --output ./pngs --convert-existing

Command Line Arguments

• -o, --output <DIR>: Output folder for PNG files (default: out)
• -e, --convert-existing: Convert all existing SVG files on startup (default: false)
• -n, --no-watch: One-time conversion without watching (no file watcher)
• -v, --version: Print version information
