Pixie - A full-featured 2D graphics library for Nim

⚠️ WARNING: This library is still in heavy development. ⚠️

Pixie is a 2D graphics library similar to Cairo and Skia written (almost) entirely in Nim.

This library is being actively developed and is not yet ready for use. Since you've managed to stumble onto it, give it a star and check back soon!

nimble install pixie

• Drawing paths, shapes and curves, with even-odd and non-zero windings.
• Strokes with joins and caps.
• Shadows, glows and blurs.
• Complex masking: Subtract, Intersect, Exclude.
• Complex blends: Darken, Multiply, Color Dodge, Hue, Luminosity... etc.
• Pixel perfect AA quality.
• Supported file formats: PNG, BMP, JPG, SVG + more in development.

Examples

Blur

examples/blur.nim

var p: Path
p.polygon(100, 100, 70, sides=6)
p.closePath()

let mask = newMask(200, 200)
mask.fillPath(p)

blur.blur(20)
blur.draw(mask, blendMode = bmMask)

image.draw(trees)
image.draw(blur)

Rounded rectangle

examples/rounded_rectangle.nim

let
  x = 50.0
  y = 50.0
  w = 100.0
  h = 100.0
  r = 25.0

var path: Path
path.roundedRect(vec2(x, y), vec2(w, h), r, r, r, r)

image.fillPath(path, rgba(255, 0, 0, 255))

Square

examples/square.nim

var p: Path
p.rect(50, 50, 100, 100)

image.fillPath(p, rgba(255, 0, 0, 255))

Tiger

examples/tiger.nim

let tiger = readImage("examples/data/tiger.svg")

image.draw(
  tiger,
  translate(vec2(100, 100)) *
  scale(vec2(0.2, 0.2)) *
  translate(vec2(-450, -450))
)
