PathNode

public sealed class PathNode(
    public val isCurve: Boolean = false,
    public val isQuad: Boolean = false,
)

Represents a single command in a vector graphics path. Each node corresponds to a command in a standard path data specification.

Members

Close

@Immutable public object Close : PathNode()

Closes the current subpath by drawing a straight line from the current point to the initial point of the subpath. RelativeClose and Close are considered the same internally, so we represent both with Close for simplicity and to make equals comparisons robust.

Corresponds to the Z or z path data commands.

RelativeMoveTo

public data class RelativeMoveTo(public val dx: Float, public val dy: Float) : PathNode()

Starts a new subpath at a point defined by a relative offset from the current point. Corresponds to the m path data command.

Parameters

MoveTo

public data class MoveTo(public val x: Float, public val y: Float) : PathNode()

Starts a new subpath at the given absolute (x,y) coordinate. Corresponds to the M path data command.

Parameters

RelativeLineTo

public data class RelativeLineTo(public val dx: Float, public val dy: Float) : PathNode()

Draws a line from the current point to a new point, defined by a relative offset. Corresponds to the l path data command.

Parameters

LineTo

public data class LineTo(public val x: Float, public val y: Float) : PathNode()

Draws a line from the current point to the specified absolute (x,y) coordinate. Corresponds to the L path data command.

Parameters

RelativeHorizontalTo

public data class RelativeHorizontalTo(public val dx: Float) : PathNode()

Draws a horizontal line from the current point, offset by a relative distance dx. Corresponds to the h path data command.

Parameters

HorizontalTo

public data class HorizontalTo(public val x: Float) : PathNode()

Draws a horizontal line from the current point to the specified absolute x-coordinate. Corresponds to the H path data command.

Parameters

RelativeVerticalTo

public data class RelativeVerticalTo(public val dy: Float) : PathNode()

Draws a vertical line from the current point, offset by a relative distance dy. Corresponds to the v path data command.

Parameters

VerticalTo

public data class VerticalTo(public val y: Float) : PathNode()

Draws a vertical line from the current point to the specified absolute y-coordinate. Corresponds to the V path data command.

Parameters
