SwiftGraphicsCore

Core geometries & protocols for a pure-Swift implementation of 2D graphics rendering.

WIP. There are probably many convenience & efficient algorithms missing. There may be missing concepts or cases.

Linear Distance

typealias SGFloat = Float64

2D Coordinates

Coordinate system assumes x+ to the right, y+ is down the page. Placing (0,0) in the upper left hand corner.

struct Point

struct Size

struct Transform2D

Bezier paths

Check out Path, SubPath, PathSegment.

Precise algorithms for whether a point is in a SubPath is done, but algorithms for decomposiing the subpaths into sub-pixel triangles is not done.

Bitmap Images

SampledImage
