Path

open class Path
kotlin.Any
   ↳ android.graphics.Path

The Path class encapsulates compound (multiple contour) geometric paths consisting of straight line segments, quadratic curves, and cubic curves. It can be drawn with canvas.drawPath(path, paint), either filled or stroked (based on the paint's Style), or it can be used for clipping or to draw text on a path.

open fun rLineTo(
    dx: Float, 
    dy: Float
): Unit

Same as lineTo, but the coordinates are considered relative to the last point on this contour. If there is no previous point, then a moveTo(0,0) is inserted automatically.

Parameters
dx Float: The amount to add to the x-coordinate of the previous point on this contour, to specify a line
dy Float: The amount to add to the y-coordinate of the previous point on this contour, to specify a line

rMoveTo

Added in API level 1
open fun rMoveTo(
    dx: Float, 
    dy: Float
): Unit

Set the beginning of the next contour relative to the last point on the previous contour. If there is no previous contour, this is treated the same as moveTo().

Parameters
dx Float: The amount to add to the x-coordinate of the end of the previous contour, to specify the start of a new contour
dy Float: The amount to add to the y-coordinate of the end of the previous contour, to specify the start of a new contour

rQuadTo

Added in API level 1
open fun rQuadTo(
    dx1: Float, 
    dy1: Float, 
    dx2: Float, 
    dy2: Float
): Unit

Same as quadTo, but the coordinates are considered relative to the last point on this contour. If there is no previous point, then a moveTo(0,0) is inserted automatically.

Parameters
dx1 Float: The amount to add to the x-coordinate of the last point on this contour, for the control point of a quadratic curve
dy1 Float: The amount to add to the y-coordinate of the last point on this contour, for the control point of a quadratic curve
dx2 Float: The amount to add to the x-coordinate of the last point on this contour, for the end point of a quadratic curve
dy2 Float: The amount to add to the y-coordinate of the last point on this contour, for the end point of a quadratic curve

reset

Added in API level 1
open fun reset(): Unit

Clear any lines and curves from the path, making it empty. This does NOT change the fill-type setting.

rewind

Added in API level 1
open fun rewind(): Unit

Rewinds the path: clears any lines and curves from the path but keeps the internal data structure for faster reuse.

set

Added in API level 1
open fun set(src: Path): Unit

Replace the contents of this with the contents of src.

Parameters
src Path: This value cannot be null.

setFillType

Added in API level 1
open fun setFillType(ft: Path.FillType): Unit

Set the path's fill type. This defines how "inside" is computed.

Parameters
ft Path.FillType: The new fill type for this path This value cannot be null.

setLastPoint

Added in API level 1
open fun setLastPoint(
    dx: Float, 
    dy: Float
): Unit

Sets the last point of the path.

Parameters
dx Float: The new X coordinate for the last point
dy Float: The new Y coordinate for the last point

toggleInverseFillType

Added in API level 1
open fun toggleInverseFillType(): Unit

Toggles the INVERSE state of the filltype

transform

Added in API level 1
open fun transform(matrix: Matrix): Unit

Transform the points in this path by matrix.

Parameters
matrix Matrix: The matrix to apply to the path This value cannot be null.

transform

Added in API level 1
open fun transform(
    matrix: Matrix, 
    dst: Path?
): Unit

Transform the points in this path by matrix, and write the answer into dst. If dst is null, then the the original path is modified.

Parameters
matrix Matrix: The matrix to apply to the path This value cannot be null.
dst Path?: The transformed path is written here. If dst is null, then the the original path is modified
