Basic Usage

Vector{
    width: 48 height: 48
    viewbox: vec4(0 0 24 24)
    Path{
        d: "M12 2L2 7l10 5 10-5-10-5zM2 17l10 5 10-5M2 12l10 5 10-5"
        fill: false
        stroke: #4488ff
        stroke_width: 2.0
        stroke_linecap: "round"
        stroke_linejoin: "round"
    }
}

Key Properties

CRITICAL: Shape Properties vs Widget Properties

Vector shapes use SVG-style properties, NOT draw_bg.* widget properties:

// CORRECT — SVG properties
Path{d:"M 0 0 L 10 10" stroke:#x66aaff stroke_width:2.5}
Circle{cx:10 cy:10 r:5 fill:#x44ddaa}

// WRONG — these do nothing on Vector shapes!
Path{d:"..." draw_bg.stroke_color:#x66aaff draw_bg.stroke_width:2.}
Circle{cx:10 cy:10 r:5 draw_bg.fill_color:#x44ddaa}

Shape Types

Path (SVG path data)

Path{
    d: "M10 10 L20 20 L10 20 Z"
    fill: #f00
    stroke: #000
    stroke_width: 1.5
}

Built-in Shapes

Rect{x: 0 y: 0 width: 100 height: 50 fill: #f00 rx: 5}
Circle{cx: 50 cy: 50 r: 25 fill: #00f}
Ellipse{cx: 50 cy: 30 rx: 40 ry: 20 fill: #0f0}
Line{x1: 0 y1: 0 x2: 100 y2: 100 stroke: #fff stroke_width: 2}
Polyline{points: "0,0 50,25 100,0" fill: false stroke: #fff}
Polygon{points: "50,0 100,100 0,100" fill: #f0f}

Gradients

Linear Gradient

Gradient{
    id: "myGrad"
    x1: 0 y1: 0 x2: 1 y2: 1
    Stop{offset: 0 color: #ff0000}
    Stop{offset: 1 color: #0000ff}
}
Path{d: "..." fill: "url(#myGrad)"}

Radial Gradient

RadGradient{
    id: "radGrad"
    cx: 0.5 cy: 0.5 r: 0.5
    Stop{offset: 0 color: #ffffff}
    Stop{offset: 1 color: #000000}
}

Groups & Transforms

Group{
    transform: "translate(10 20) rotate(45 50 50)"
    opacity: 0.8

    Circle{cx: 0 cy: 0 r: 10 fill: #f00}
    Rect{x: 20 y: 0 width: 20 height: 20 fill: #0f0}
}

Filters

Filter{
    id: "shadow"
    DropShadow{dx: 2 dy: 2 blur: 4 color: #0008}
}
Path{d: "..." fill: #fff filter: "url(#shadow)"}

Tween Animation (SVG Property Animation)

CRITICAL: Tween is a property value, NOT a container. It replaces a shape property (fill, stroke, opacity, cx, cy, r, etc.) with an animated value.

Basic Syntax

// Animate opacity (pulse effect)
Circle{cx:8 cy:8 r:6 fill:#x44ddaa opacity:Tween{from:0.3 to:1.0 dur:1.5 loop_:true}}

// Animate position (moving dot)
Circle{cx:Tween{from:20 to:380 dur:3.0 loop_:true} cy:25 r:5 fill:#x66aaff}

// Animate color
Circle{fill:Tween{from:#x44ddaa to:#x6688dd dur:3.0 loop_:true} cx:10 cy:10 r:8}

// Animate stroke
Path{d:"M 0 0 L 100 0" stroke:Tween{from:#x333333 to:#x66aaff dur:2.0 loop_:true} stroke_width:2.}

CRITICAL: loop_ Must Be Boolean

// CORRECT — indefinite loop
