AddCurve

voidAddCurve(PointPoint1, PointPoint2, PointPoint3)

Parameters

Point1: Point

first Bezier control point

Point2: Point

second Bezier control point

Point3: Point

the ending Point of the Bezier curve which will also be the current point of the current path.

Returns:

void

Adds a Bezier curve from the current path using the first two points specified as Bezier control points ending at the third point. The new current point is then set to the third point.

AddCurveV

voidAddCurveV(PointPoint1, PointPoint2)

Parameters

Point1: Point

first Bezier control point

Point2: Point

the ending Point of the Bezier curve which will also be the new current point of the path.

Returns:

void

Adds a Bezier curve from the current path. This extends from the current path to the point Point2 using the current point and the first point specified as Bezier control points ending at the second point. The new current point is then set to the second point.

AddCurveY

voidAddCurveY(PointPoint1, PointPoint2)

Parameters

Point1: Point

first Bezier control point

Point2: Point

second Bezier control point and the ending Point of the Bezier curve which will also be the new current point of the path.

Returns:

void

Adds a Bezier curve from the current path. This extends from the current path to the point Point2 using the two points specified as Bezier control points ending at the second point. The new current point is then set to the second point.

AddLine

voidAddLine(PointPoint)

Parameters

Point: Point

the coordinates of the endpoint of the new line.

Returns:

void

Adds a line to the current path from the current path position. The given point becomes the new current position.

AddRect

voidAddRect(PointPoint, doubleWidth, doubleHeight)

Parameters

Point: Point

the coordinates of the lower left corner of the new rectangle.

Width: double

the width of the new rectangle.

Height: double

the height of the new rectangle.

Returns:

void

Adds a rectangle to the current path with the lower left corner at the give point, and with the width and height specified.

Clone

new PathClone()

Returns:

The copied path.

Makes a copy of the path.

Make a copy of an path to obtain a new path that has a distinct set of attributes.

Clone

new PathClone(ElementCloneFlagscloneFlags)

Parameters

cloneFlags: ElementCloneFlags

Flags that modify the cloning operation.

Returns:

The copied path.

Makes a copy of the path.

Make a copy of an path to obtain a new path that has a distinct set of attributes.

ClosePath

voidClosePath()

Returns:

void

Closes the current subpath.

ColorConvert

PathColorConvert(Documentdocument, ColorProfileprof, RenderIntentintent, boolembed)

Parameters

document: Document

The document the element belongs to.

prof: ColorProfile

The ICC ColorProfile to be applied.

intent: RenderIntent

The ICC Rendering Intent for the ColorProfile

embed: bool

If true, embed the color space and make the object calibrated. If it is false and the target profile is CMYK, RGB, or Gray, the colors space of the resulting object, after conversion, will be DeviceCMYK, DeviceRGB, or DeviceGray, respectively.

Returns:

A new Path with the applied ICC ColorProfile.

Applies the specified ICC ColorProfile to the Path

ConstructorRetrieve

Returns:

void

MoveTo

voidMoveTo(PointPoint)

Parameters

Point: Point

Rotate

voidRotate(doubletheta)

Parameters

theta: double

Returns:

void

Rotate an element by T degrees counterclockwise units using the matrix [ cos T sin T -sin T cos T 0 0 ].

Scale

voidScale(doublesx, doublesy)

Parameters

sx: double
sy: double

Returns:

void

Scale an element by (sx,sy) units using the matrix [ sx 0 0 sy 0 0 ].

Translate
