Drawing

pub struct Drawing {
  // private fields
}

A prepared SVG snapshot with immutable semantic hit targets and no UI types.

Drawing::height

source

fn Drawing::height(self : Drawing) -> Int

Drawing::hit_info

source

fn Drawing::hit_info(self : Drawing, point : HitPoint) -> HitInfo?

Look up metadata by exact point equality within this prepared frame.

Drawing::hit_test

source

fn Drawing::hit_test(self : Drawing, x : Double, y : Double, radius? : Double, mode? : HitMode) -> HitPoint?

Hit-test intrinsic drawing coordinates. Areas win in reverse paint order; point anchors use radius and stable distance ties. XNearest prioritizes nearby non-line points, then selects line samples by screen X inside the panel. Legacy drawings without semantic targets retain nearest-point behavior.

Drawing::hit_test_client

source

fn Drawing::hit_test_client(self : Drawing, client_x : Double, client_y : Double, left : Double, top : Double, width : Double, height : Double, radius? : Double, mode? : HitMode) -> HitPoint?

Hit-test client coordinates with a radius measured in CSS pixels.

Drawing::points

source

fn Drawing::points(self : Drawing) -> Array[HitPoint]

Return a copy; mutating it cannot change this drawing's hit targets.

Drawing::svg

source

fn Drawing::svg(self : Drawing) -> String

Drawing::targets

source

fn Drawing::targets(self : Drawing) -> Array[HitTarget]

Return an independent array; target values contain no mutable collections.

Drawing::viewport_point

source

fn Drawing::viewport_point(self : Drawing, client_x : Double, client_y : Double, left : Double, top : Double, width : Double, height : Double) -> (Double, Double)?

Convert client coordinates for an SVG viewBox="0 0 width height" with preserveAspectRatio="xMidYMid meet". Outside and letterbox hits are absent. The rectangle must be the actual SVG viewport's client rectangle.

Drawing::width

source

fn Drawing::width(self : Drawing) -> Int

HitInfo

source

pub struct HitInfo {
  point : HitPoint
  kind : HitKind
  series : String
  category : String?
  value : Double
  interval : (Double, Double)?
  fraction : Double?
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

Semantic values captured with the same immutable frame as its hit point.

HitInfo::equal

source

fn HitInfo::equal(HitInfo, HitInfo) -> Bool

HitInfo::not_equal

source

fn HitInfo::not_equal(x : HitInfo, y : HitInfo) -> Bool

HitInfo::to_repr

source

fn HitInfo::to_repr(HitInfo) -> @moonbitlang/core/debug.Repr
Repr

HitKind

source

pub(all) enum HitKind {
  Line
  Scatter
  Bar
  BarH
  Histogram
  Pie
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

The plotted primitive described by a hit target.

HitKind::equal

source

fn HitKind::equal(HitKind, HitKind) -> Bool

HitKind::not_equal

source

fn HitKind::not_equal(x : HitKind, y : HitKind) -> Bool

HitKind::to_repr

source

fn HitKind::to_repr(HitKind) -> @moonbitlang/core/debug.Repr
Repr

HitMode

source

pub(all) enum HitMode {
  Nearest
  XNearest
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

XNearest falls back to a real line sample nearest in screen X inside a panel.

HitMode::equal

source

fn HitMode::equal(HitMode, HitMode) -> Bool

HitMode::not_equal

source

fn HitMode::not_equal(x : HitMode, y : HitMode) -> Bool

HitMode::to_repr

source

fn HitMode::to_repr(HitMode) -> @moonbitlang/core/debug.Repr
Repr

HitPoint

source

pub struct HitPoint {
  panel_index : Int
  artist_index : Int
  point_index : Int
  data_x : Double
  data_y : Double
  screen_x : Double
  screen_y : Double
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

A data-point anchor and its intrinsic drawing coordinates. Indices identify a point within this frame's panel and artist ordering.

HitPoint::equal

source

fn HitPoint::equal(HitPoint, HitPoint) -> Bool

HitPoint::not_equal

source

fn HitPoint::not_equal(x : HitPoint, y : HitPoint) -> Bool

HitPoint::to_repr

source

fn HitPoint::to_repr(HitPoint) -> @moonbitlang/core/debug.Repr
Repr

HitShape

source

pub(all) enum HitShape {
  Point
  Rectangle(Double, Double, Double, Double)
  Sector(Double, Double, Double, Double, Double)
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

Intrinsic drawing geometry. Rectangles use left, top, width, height. Sectors use center X/Y, radius, start degrees and positive CCW sweep degrees; angles follow mathematical coordinates, with the screen Y direction reversed. Nonpositive sizes/sweeps and nonfinite geometry do not hit; rectangle and sector edges are included, and sweeps of at least 360 degrees are full circles.

HitShape::equal

source

fn HitShape::equal(HitShape, HitShape) -> Bool

HitShape::not_equal

source

fn HitShape::not_equal(x : HitShape, y : HitShape) -> Bool

HitShape::to_repr

source

fn HitShape::to_repr(HitShape) -> @moonbitlang/core/debug.Repr
Repr

HitTarget

source

pub struct HitTarget {
  info : HitInfo
  shape : HitShape
  bounds : (Double, Double, Double, Double)
} derive(Eq, @moonbitlang/core/debug.Debug
Debug)

A hit geometry and the displayed panel rectangle that clips it.

HitTarget::equal

source

fn HitTarget::equal(HitTarget, HitTarget) -> Bool

HitTarget::not_equal

source

fn HitTarget::not_equal(x : HitTarget, y : HitTarget) -> Bool

HitTarget::to_repr

source

fn HitTarget::to_repr(HitTarget) -> @moonbitlang/core/debug.Repr
Repr

drawing

source

fn drawing(width : Int, height : Int, svg : String, points : Array[HitPoint], targets? : Array[HitTarget], exclusions? : Array[(Int, (Double, Double, Double, Double))]) -> Drawing

Capture independent copies of point, semantic-target and exclusion arrays. Exclusions are (panel index, intrinsic left/top/width/height) overlay rectangles.

hit_info

source

fn hit_info(point : HitPoint, kind : HitKind, value~ : Double, series? : String, category? : String?, interval? : (Double, Double)?, fraction? : Double?) -> HitInfo

hit_point

source

fn hit_point(panel_index : Int, artist_index : Int, point_index : Int, data_x : Double, data_y : Double, screen_x : Double, screen_y : Double) -> HitPoint

hit_target

source

fn hit_target(info : HitInfo, shape : HitShape, bounds : (Double, Double, Double, Double)) -> HitTarget
