public class Path
extends Object

java.lang.Object
↳	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.

quadTo

Added in API level 1

public void quadTo (float x1, 
                float y1, 
                float x2, 
                float y2)

Add a quadratic bezier from the last point, approaching control point (x1,y1), and ending at (x2,y2). If no moveTo() call has been made for this contour, the first point is automatically set to (0,0).

Parameters
x1	float: The x-coordinate of the control point on a quadratic curve
y1	float: The y-coordinate of the control point on a quadratic curve
x2	float: The x-coordinate of the end point on a quadratic curve
y2	float: The y-coordinate of the end point on a quadratic curve

rConicTo

Added in API level 34

public void rConicTo (float dx1, 
                float dy1, 
                float dx2, 
                float dy2, 
                float weight)

Same as conicTo, 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 conic curve
dy1	float: The amount to add to the y-coordinate of the last point on this contour, for the control point of a conic curve
dx2	float: The amount to add to the x-coordinate of the last point on this contour, for the end point of a conic curve
dy2	float: The amount to add to the y-coordinate of the last point on this contour, for the end point of a conic curve
weight	float: The weight of the conic applied to the curve. A value of 1 is equivalent to a quadratic with the given control and anchor points and a value of 0 is equivalent to a line to the first and another line to the second point.

rCubicTo

Added in API level 1

public void rCubicTo (float x1, 
                float y1, 
                float x2, 
                float y2, 
                float x3, 
                float y3)

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

Parameters
x1	float
y1	float
x2	float
y2	float
x3	float
y3	float

rLineTo

Added in API level 1

public void rLineTo (float dx, 
                float dy)

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

public void rMoveTo (float dx, 
                float dy)

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

public void rQuadTo (float dx1, 
                float dy1, 
                float dx2, 
                float dy2)

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

public void reset ()

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

public void rewind ()

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

public void set (Path src)

Replace the contents of this with the contents of src.

Parameters
src	Path: This value cannot be null.

setFillType

Added in API level 1

public void setFillType (Path.FillType ft)

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

public void setLastPoint (float dx, 
                float dy)

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

public void toggleInverseFillType ()

Toggles the INVERSE state of the filltype

transform

Added in API level 1

public void transform (Matrix matrix)

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

public void transform (Matrix matrix, 
                Path dst)

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
