## RSKCoreGraphics
RSKCoreGraphics is a comprehensive library for working with Core Graphics in iOS. This library provides an easy and convenient way to handle and manipulate different components of Core Graphics.
## Features
– **RSKBezierPath**: A utility class for creating complex bezier paths with ease.
– **RSKGradientLayer**: A subclass of `CAGradientLayer` that allows for easy creation and customization of gradients.
– **RSKPDFRenderer**: A utility class for rendering PDF files from multiple views.
– **RSKImageMasking**: A set of methods for masking images based on alpha, luminance, and transparency.
– **RSKNibSizeCalculator**: A utility class for calculating the size of views from their NIB files, taking autolayout into account.
## Installation
To install RSKCoreGraphics, simply follow these steps:
1. Open your Terminal and navigate to your project directory.
2. Run the following command to clone the RSKCoreGraphics repository:
“`bash
git clone https://github.com/your-username/RSKCoreGraphics.git
“`
3. Drag and drop the RSKCoreGraphics folder into your Xcode project.
4. In Xcode, go to your project’s **Build Phases**.
5. Expand the **Compile Sources** section.
6. Add the necessary `.m` files from the RSKCoreGraphics folder to the list of compiled sources. Make sure these files are included in your project’s **Target Membership** as well.
## Usage
RSKCoreGraphics provides a variety of classes and utilities to enhance your Core Graphics workflows. Here are some examples of how to use them:
### RSKBezierPath
RSKBezierPath allows you to create and manipulate complex bezier paths. Here’s an example of how to draw a rounded rectangle:
“`swift
import RSKCoreGraphics
let roundedRect = RSKBezierPath(roundedRect: CGRect(x: 0, y: 0, width: 200, height: 100), cornerRadius: 10)
roundedRect.lineWidth = 2
roundedRect.stroke()
“`
### RSKGradientLayer
RSKGradientLayer makes it simple to create and customize gradients. Here’s an example of how to create and add a gradient layer to a view:
“`swift
import RSKCoreGraphics
let gradientLayer = RSKGradientLayer()
gradientLayer.frame = view.bounds
gradientLayer.startColor = UIColor.red.cgColor
gradientLayer.endColor = UIColor.blue.cgColor
view.layer.addSublayer(gradientLayer)
“`
### RSKPDFRenderer
RSKPDFRenderer allows you to render multiple views into a PDF file. Here’s an example of how to generate a PDF from multiple views:
“`swift
import RSKCoreGraphics
let renderer = RSKPDFRenderer()
renderer.include(view1, view2, view3)
let pdfData = renderer.renderPDF()
“`
### RSKImageMasking
RSKImageMasking provides methods for masking images based on their alpha, luminance, and transparency. Here’s an example of how to mask an image with transparency:
“`swift
import RSKCoreGraphics
let maskedImage = RSKImageMasking.maskImage(image, withMask: maskImage)
“`
### RSKNibSizeCalculator
RSKNibSizeCalculator helps calculate the size of views loaded from NIB files, taking auto layout into account. Here’s an example of how to calculate the size of a view from its NIB file:
“`swift
import RSKCoreGraphics
let sizeCalculator = RSKNibSizeCalculator(nibName: “CustomView”)
let viewSize = sizeCalculator.calculateSize()
“`
## Compatibility
RSKCoreGraphics is compatible with iOS 9.0 and above. It is written in Swift and requires Swift 4.2 or later.
