Doggie - A Cross-platform Library for Swift

Doggie is a foundational library for Apple's swift. It includes mathematics, accelerate, signal processing and graphic functions.

Apps Using This Library

Features

accelerate, signal processing, fourier and convolution
complex number, point, vector and 2D/3D transformation
bezier curve
polynomial
color and color space
shape and boolean operation

let shape = try Shape(code: "M100 0c0-100-236.60 36.60-150 86.60S36.60-136.60-50-86.60 100 100 100 0z")

let region = ShapeRegion(shape, winding: .nonZero)
let ellipse = ShapeRegion(ellipseIn: shape.boundary)

operation	preview
`region.union(ellipse)`
`region.intersection(ellipse)`
`ellipse.subtracting(region)`
`region.subtracting(ellipse)`
`region.symmetricDifference(ellipse)`

font

let collection = try FontCollection(data: fontFileData)

if let font = collection.first?.with(size: 64) {

    let string = "Doggie\u{0301}".precomposedStringWithCanonicalMapping

    let glyphs = font.glyphs(with: string.unicodeScalars)
    let advances = glyphs.map { font.advance(forGlyph: $0) }.reductions(0, +)

    var shape = Shape()

    for (advance, glyph) in zip(advances, glyphs) {
        var outline = font.shape(forGlyph: glyph)
        outline.center.x += advance
        shape.append(contentsOf: outline.identity)
    }

    print(shape.encode())
}

image and graphics with 2D/3D drawing

let context = ImageContext<ARGB32ColorPixel>(width: 100, height: 100, colorSpace: ColorSpace.sRGB)

let ellipse1 = Shape(ellipseIn: Rect(x: 10, y: 35, width: 55, height: 55))
let ellipse2 = Shape(ellipseIn: Rect(x: 35, y: 10, width: 55, height: 55))

context.draw(shape: ellipse1, winding: .nonZero, color: RGBColorModel(red: 247/255, green: 217/255, blue: 12/255))
context.draw(shape: ellipse1, stroke: Stroke(width: 1, cap: .round, join: .round, color: RGBColorModel()))
context.draw(shape: ellipse2, winding: .nonZero, color: RGBColorModel(red: 234/255, green: 24/255, blue: 71/255))
context.draw(shape: ellipse2, stroke: Stroke(width: 1, cap: .round, join: .round, color: RGBColorModel()))

let image: Image<ARGB32ColorPixel> = context.image
