Doggie is a foundational library for Apple's swift. It includes mathematics, accelerate, signal processing and graphic functions.
## Apps Using This Library
[
](https://apps.apple.com/hk/app/doggie-graffiti/id1465865578)
## Features
- accelerate, signal processing, fourier and convolution
- complex number, point, vector and 2D/3D transformation
- bezier curve
- [polynomial](docs/Polynomial.md)
- [color](docs/Color.md) and [color space](docs/ColorSpace.md)
- [shape](docs/Shape.md) and [boolean operation](docs/ShapeRegion.md)
```swift
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](docs/Font.md)
```swift
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](docs/Image.md) and [graphics](docs/ImageContext.md) with 2D/3D drawing
```swift
let context = ImageContext(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 = context.image
```
- others
```svg
```
```swift
let context = ImageContext(width: 220, height: 220, colorSpace: .default)
context.draw(ellipseIn: Rect(x: 0, y: 0, width: 200, height: 200), color: .black)
var image = context.image
let turbulence: Image = SVGTurbulence(220, 220, .turbulence, nil, .identity, 0, 0.05, 2)
image = DisplacementMap(image, turbulence, 0, 1, 50)
```
