Mandelbrot Set Renderer

This Rust program generates grayscale images of the Mandelbrot set and saves them as PNG files. It uses multi-threading for efficient rendering and supports custom image dimensions and complex plane coordinates.

Features

• Renders Mandelbrot set images in PNG format
• Multi-threaded rendering for performance
• Customizable image size and complex plane region
• Simple command-line interface

Usage

./mandelbrot FILE PIXELS LEFT,TOP RIGHT,BOTTOM

• FILE: Output PNG filename (e.g., mandel.png)
• PIXELS: Image dimensions in the format WIDTHxHEIGHT (e.g., 1000x750)
• LEFT,TOP: Upper-left complex coordinate (e.g., -1.20,0.35)
• RIGHT,BOTTOM: Lower-right complex coordinate (e.g., -1,0.20)

Example

./mandelbrot mandel.png 1000x750 -1.20,0.35 -1,0.20

This command generates a 1000x750 PNG image of the Mandelbrot set covering the specified region of the complex plane.

Building

Make sure you have Rust installed.

cargo build --release

The executable will be located at target/release/mandelbrot.

Running

After building, run the program as shown in the usage section. The output image will be saved to the specified file.
