goFractal

Description

The goFractal library is a Go package for generating fractals. This library provides support for both PNG and GIF formats. You can specify the focus points and zoom level for more detailed fractals.

Installation

To install the package, run:

go get -u github.com/leorighi/goFractal

Usage

Import the Package

First, import the package in your Go file:

import "github.com/leorighi/goFractal"

Initialize Mandelbrot struct

Initialize a new Mandelbrot struct with your preferred dimensions:

m := &goFractal.Mandelbrot{
    Width:  800,
    Height: 800,
}

Generate PNG Image

To generate a PNG image:

err := m.GeneratePNG("mandelbrot.png", 0.0, 0.0)
if err != nil {
    return err
}

Generate GIF Animation

To generate a GIF animation:

err := m.GenerateGIF("output.gif", 30, -1.4017, 0.0, 0.20)
if err != nil {
    // Handle error
}

Methods

GeneratePNG

Generates a PNG image file of the Mandelbrot fractal.

• filename: The name of the output PNG file.
• focusX: X-coordinate of the focus point.
• focusY: Y-coordinate of the focus point.

Returns an error if the operation fails.

func (m *Mandelbrot) GeneratePNG(filename string, focusX float64, focusY float64) error

GenerateGIF

Generates a GIF image file with animated zoom of the Mandelbrot fractal.

• filename: The name of the output GIF file.
• frames: Number of frames in the animation.
• focusX: X-coordinate of the focus point.
• focusY: Y-coordinate of the focus point.
• zoomSpeed: Zoom speed for animation.

Returns an error if the operation fails.

func (m *Mandelbrot) GenerateGIF(filename string, frames int, focusX float64, focusY float64, zoomSpeed float64) error
