Core Graphics Extended Library is aiming to complete missing conveniences in Core Graphics.

Get Started

Cocoa Pods

pod "CoreGraphicsExt"

Manually Install

• Download Core Graphics Extended Library
• Drag Core Graphics Extended Library’s Xcode project file to your workspace
• Add Core Graphics Extended Library to yourEmebed Binaries field in your target’s general page if you are building an app. Or add Core Graphics Extended Library to your Linked Frameworks and Libraries field in your target’s general page if you are building a framework.
• Add import CoreGraphicsExt to your Swift source file
• Enjoy your journey of Core Graphics Extended Library

What This Library Extends With

Linear Mixing

You can now linear mix CGFloat, CGPoint and CGSize now

Geometric Position Detection

You can now check:

• If a CGPoint value is inside a circle which is the biggest circle inside the given CGRect value
• If a CGPoint value is on the circumference of a circle which is the biggest circle inside the given CGRect value
• If a CGPoint value is inside a CGRect value
• If a CGPoint value is on the circumference of a CGRect value
• If a CGRect value touches an other.

More Conveniences on Value Creation

You can now create CGRect value with:

• Center and size
• Center, width and height
• A given CGRect value and optional origin and size
• CGPoint values which require created CGRect value to cover
• CGRect values which require created CGRect value to cover

You also can now create CGRect value by:

• Swapping width and height
• Modify a given CGRect value’s origin or size

You can now create CGPoint value with

• Definite proportion and seperated points

Integral And Align to Screen Pixel

You can now integral CGFloat, CGPoint, CGSize and CGRect value by accessing their integral property.

You can now algin CGFloat, CGPoint, CGSize and CGRect value to screen pixel by calling func alignToScreenPixel(policy: ScreenPixelAlignmentPolicy) function on those value.

Arithmetic Operation on CGPoint And CGSize Value

You can +, - a CGPoint value with an other now. You can *, / a CGPoint value with a CGFloat value now You can make a dot product with two CGPoint values now.

You can +, - a CGSize value with an other now. You can *, / a CGSize value with a CGFloat or an Int value now

More Functionalities Can Be Found Inside The Library

• Get distance between two CGPoint values
• Get mid point between two CGPoint values
• Get max and min side length of CGSize value
• Enumerate each vertex on a CGRect value
