CGExtender

Useful extensions and functions used with coregraphics types like CGFloat, CGPoint, and CGSize

CGPoint

• VectorArithmetic Conformance
• Random Value in range

CGSize

• VectorArithmetic Conformance
• Random Value in range

Clamping Functions

Clamps within range of two given values

Geometry Functions

• atanP - function returns only positive values between [0, 2π]
• calculateDirection -Calculates the direction between two points relative to the vector pointing in the trailing direction
• project - Projects the point p onto the line segment defined by the points L1 and L2
• calculateParameter - Projects the point p onto the vector defined by the points L1 and L2, uses the parametric form of the line segment from L1 to L2 to constrain the projected point to be on the line segment
• distance - gets the distance between two points
