PocketSVG is a lightweight Swift library for parsing and rendering Scalable Vector Graphics (SVG) files. With PocketSVG, you can easily import SVG files into your iOS projects and manipulate them as needed. This documentation will guide you through the installation process, provide an overview of the library’s capabilities, and explain how to use its various features.

Installation

To integrate PocketSVG into your iOS project, you can use CocoaPods or manually add the library to your project. Follow the steps below based on your preferred installation method:

Using CocoaPods

  1. Add the following line to your Podfile: 
    pod 'PocketSVG'
  2. Run the command: 
    pod install
  3. Import the library in your Swift files using: 
    import PocketSVG

Manual Installation

  1. Download the latest version of PocketSVG from the GitHub repository: https://github.com/pocketsvg/PocketSVG
  2. Drag and drop the PocketSVG.swift file into your Xcode project, ensuring “Copy items if needed” is checked.
  3. Make sure the file is added to your target’s “Compile Sources” build phase.
  4. You’re ready to start using PocketSVG in your project!

Usage

PocketSVG provides a simple and intuitive API for working with SVG files. The main features include parsing SVG paths, rendering paths to a CGContext, and manipulating paths programmatically. Here’s an overview of how to use PocketSVG in your iOS projects:

Parsing SVG Paths

To parse an SVG path, you can use the static `SVGBezierPath.paths(fromSVGFileAt: String)` method. This method takes the path to the SVG file as a parameter and returns an array of `UIBezierPath` objects representing the parsed paths. Here’s an example: 

let paths = SVGBezierPath.paths(fromSVGFileAt: "path/to/your/svg/file.svg")

Rendering Paths

To render a parsed SVG path to a `CGContext`, you can use the `UIBezierPath`’s `stroke()` and `fill()` methods. For example, you can render a path with a red stroke color and a blue fill color as follows: 

let path = SVGBezierPath.path(fromSVGFileAt: "path/to/your/svg/file.svg")
let context = UIGraphicsGetCurrentContext()
context?.setStrokeColor(UIColor.red.cgColor)
context?.setFillColor(UIColor.blue.cgColor)
path.stroke()
path.fill()

Manipulating Paths

PocketSVG also provides convenient methods for manipulating paths programmatically. You can transform, scale, translate, and manipulate path elements with ease. Here’s an example of scaling a path by a factor of 2: 

let path = SVGBezierPath.path(fromSVGFileAt: "path/to/your/svg/file.svg")
path.scale(to: CGSize(width: path.bounds.size.width * 2, height: path.bounds.size.height * 2))

Conclusion

PocketSVG offers a hassle-free solution for integrating SVG files into your iOS projects. With its lightweight and easy-to-use features, you can leverage the power of vector graphics in your app development. Whether you need to parse, render, or manipulate SVG paths, PocketSVG has got you covered. Start using PocketSVG today and unlock endless possibilities for creating stunning visual experiences!
