AndroidPath(internalPath: Path = android.graphics.Path())

addArc

fun addArc(
    oval: Rect, 
    startAngleDegrees: Float, 
    sweepAngleDegrees: Float
): Unit

Adds a new subpath with one arc segment that consists of the arc that follows the edge of the oval bounded by the given rectangle, from startAngle degrees around the oval up to startAngle + sweepAngle degrees around the oval, with zero degrees being the point on the right hand side of the oval that crosses the horizontal line that intersects the center of the rectangle and with positive angles going clockwise around the oval.

addArcRad

fun addArcRad(
    oval: Rect, 
    startAngleRadians: Float, 
    sweepAngleRadians: Float
): Unit

Adds a new subpath with one arc segment that consists of the arc that follows the edge of the oval bounded by the given rectangle, from startAngle radians around the oval up to startAngle + sweepAngle radians around the oval, with zero radians being the point on the right hand side of the oval that crosses the horizontal line that intersects the center of the rectangle and with positive angles going clockwise around the oval.

addOval

fun addOval(oval: Rect): Unit

Adds a new subpath that consists of a curve that forms the ellipse that fills the given rectangle.

To add a circle, pass an appropriate rectangle as oval. Rect can be used to easily describe the circle's center Offset and radius.

addPath

fun addPath(
    path: Path, 
    offset: Offset
): Unit

Adds a new subpath that consists of the given path offset by the given offset.

If matrix4 is specified, the path will be transformed by this matrix after the matrix is translated by the given offset. The matrix is a 4x4 matrix stored in column major order.

addRect

fun addRect(rect: Rect): Unit

Adds a new subpath that consists of four lines that outline the given rectangle.

addRoundRect

fun addRoundRect(roundRect: RoundRect): Unit

Add a round rectangle shape to the path from the given RoundRect

arcTo

fun arcTo(
    rect: Rect, 
    startAngleDegrees: Float, 
    sweepAngleDegrees: Float, 
    forceMoveTo: Boolean
): Unit

If the forceMoveTo argument is false, adds a straight line segment and an arc segment.

If the forceMoveTo argument is true, starts a new subpath consisting of an arc segment.

In either case, the arc segment consists of the arc that follows the edge of the oval bounded by the given rectangle, from startAngle degrees around the oval up to startAngle + sweepAngle degrees around the oval, with zero degrees being the point on the right hand side of the oval that crosses the horizontal line that intersects the center of the rectangle and with positive angles going clockwise around the oval.

The line segment added if forceMoveTo is false starts at the current point and ends at the start of the arc.

close

fun close(): Unit

Closes the last subpath, as if a straight line had been drawn from the current point to the first point of the subpath.

cubicTo

fun cubicTo(
    x1: Float, 
    y1: Float, 
    x2: Float, 
    y2: Float, 
    x3: Float, 
    y3: Float
): Unit

Adds a cubic bezier segment that curves from the current point to the given point (x3, y3), using the control points (x1, y1) and (x2, y2).

getBounds

fun getBounds(): Rect

Compute the bounds of the control points of the path, and write the answer into bounds. If the path contains 0 or 1 points, the bounds is set to (0,0,0,0)

lineTo

fun lineTo(
    x: Float, 
    y: Float
): Unit

Adds a straight line segment from the current point to the given point

moveTo

fun moveTo(
    x: Float, 
    y: Float
): Unit

Starts a new subpath at the given coordinate

op

fun op(
    path1: Path, 
    path2: Path, 
    operation: PathOperation
): Boolean

Set this path to the result of applying the Op to the two specified paths. The resulting path will be constructed from non-overlapping contours. The curve order is reduced where possible so that cubics may be turned into quadratics, and quadratics maybe turned into lines.

quadraticBezierTo

fun quadraticBezierTo(
    x1: Float, 
    y1: Float, 
    x2: Float, 
    y2: Float
): Unit

Adds a quadratic bezier segment that curves from the current point to the given point (x2, y2), using the control point (x1, y1).

relativeCubicTo

fun relativeCubicTo(
    dx1: Float, 
    dy1: Float, 
    dx2: Float, 
    dy2: Float, 
    dx3: Float, 
    dy3: Float
): Unit

Adds a cubic bezier segment that curves from the current point to the point at the offset (dx3, dy3) from the current point, using the control points at the offsets (dx1, dy1) and (dx2, dy2) from the current point.

relativeLineTo

fun relativeLineTo(
    dx: Float, 
    dy: Float
): Unit

Adds a straight line segment from the current point to the point at the given offset from the current point.

relativeMoveTo

fun relativeMoveTo(
    dx: Float, 
    dy: Float
): Unit

Starts a new subpath at the given offset from the current point

relativeQuadraticBezierTo

fun relativeQuadraticBezierTo(
    dx1: Float, 
    dy1: Float, 
    dx2: Float, 
    dy2: Float
): Unit

Adds a quadratic bezier segment that curves from the current point to the point at the offset (dx2, dy2) from the current point, using the control point at the offset (dx1, dy1) from the current point.

reset

fun reset(): Unit

Clears the Path object of all subpaths, returning it to the same state it had when it was created. The current point is reset to the origin.

translate

fun translate(offset: Offset): Unit

Translates all the segments of every subpath by the given offset.

fillType

var fillType: PathFillType

Determines how the interior of this path is calculated.

Defaults to the non-zero winding rule, PathFillType.NonZero.

internalPath

val internalPath: Path

isConvex

val isConvex: Boolean

Returns the path's convexity, as defined by the content of the path.

A path is convex if it has a single contour, and only ever curves in a single direction.

This function will calculate the convexity of the path from its control points, and cache the result.

isEmpty

val isEmpty: Boolean

Returns true if the path is empty (contains no lines or curves)
