Svg.Editor.Skia

Svg.Editor.Skia contains the editing math and overlay-rendering helpers used by the interactive canvas.

Install

dotnet add package Svg.Editor.Skia

Choose this package when

you are building your own canvas or surface control,
you need reusable handle hit-testing, transform math, and path editing,
you want align/distribute helpers for selected SVG elements,
you want the editor overlay renderer without taking the Avalonia workspace.

Main types

Type	Role
`SvgEditorInteractionController`	Public adapter over selection and path-edit behavior
`SvgEditorOverlayRenderer`	Public adapter over overlay drawing
`SelectionService`	Bounds, transforms, resizing, skewing, flipping, and handle hit-testing
`PathService`	Editable path points and path operations
`AlignService`	Align and distribute commands
`RenderingService`	Grid, layer, selection, and path overlay drawing
`BoundsInfo`	Computed selection handles
`PathPoint`	Individual editable path point

Minimal setup

using Svg.Editor.Skia;

var interaction = new SvgEditorInteractionController
{
    SnapToGrid = true,
    GridSize = 10
};

var overlays = new SvgEditorOverlayRenderer();

In a custom surface, the interaction controller is the entry point for:

GetBoundsInfo(...)
HitHandle(...)
SetRotation(...)
SetTranslation(...)
SetScale(...)
SetSkew(...)
ResizeElement(...)
path-edit operations such as StartPathEditing(...), MoveActivePathPoint(...), and MakePathPointSmooth(...)

Relationship to the higher packages

Svg.Editor.Skia.Avalonia exposes these helpers on SvgEditorSurface through the InteractionController and OverlayRenderer properties. Use Svg.Editor.Skia directly only when the host owns the rest of the UI composition.
