Constructor Details

AbstractPathShape

public AbstractPathShape()

Creates new AbstractPathShape instance.

AbstractPathShape

public AbstractPathShape(boolean relative)

Creates new AbstractPathShape instance.

Parameters:

relative - boolean defining whether this is a relative operator

AbstractPathShape

public AbstractPathShape(boolean relative,
 IOperatorConverter copier)

Creates new AbstractPathShape instance.

Parameters:

relative - boolean defining whether this is a relative operator

copier - IOperatorConverter copier for converting relative coordinates to absolute coordinates

Method Details

isRelative

public boolean isRelative()

Description copied from interface: IPathShape

Returns true when this shape is a relative operator. False if it is an absolute operator.

Specified by:

isRelative in interface IPathShape

Returns:

true if relative, false if absolute

createPoint

protected Point createPoint(String coordX,
 String coordY)

Creates Point based on provided x and y coordinates.

Parameters:

coordX - x coordinate of the point

coordY - y coordinate of the point

Returns:

created Point instance

getEndingPoint

public Point getEndingPoint()

Description copied from interface: IPathShape

Gets the ending point on the canvas after the path shape has been drawn via the IPathShape.draw(PdfCanvas) method, in SVG space coordinates.

Specified by:

getEndingPoint in interface IPathShape

Returns:

The Point representing the final point in the drawn path. If the point does not exist or does not change null may be returned.

getPathShapeRectangle

public Rectangle getPathShapeRectangle(Point lastPoint)

Get bounding rectangle of the current path shape.

Specified by:

getPathShapeRectangle in interface IPathShape

Parameters:

lastPoint - start point for this shape

Returns:

calculated rectangle

draw

public void draw(PdfCanvas canvas)

Description copied from interface: IPathShape

Draws this instruction to a canvas object.

Deprecated in favour of draw() and later this method should be introduced in this interface, along with setContext(SvgDrawContext) method. Since canvas can be got from SvgDrawContext the PdfCanvas parameter is no more needed.

Specified by:

draw in interface IPathShape

Parameters:

canvas - to which this instruction is drawn

draw

public abstract void draw()

Draws this instruction to a canvas object.

setParent

public void setParent(PathSvgNodeRenderer parent)

Set parent path for this shape.

Parameters:

parent - PathSvgNodeRenderer instance

setContext

public void setContext(SvgDrawContext context)

Set svg draw context for this shape.

Parameters:

context - SvgDrawContext instance.

setTransform

public void setTransform(AffineTransform transform)

Sets AffineTransform to apply before drawing the shape.

Parameters:

transform - AffineTransform to apply before drawing

parseHorizontalLength

protected float parseHorizontalLength(String length)

Parse x axis length value.

Parameters:

length - String length for parsing

Returns:

absolute length in points

parseVerticalLength

protected float parseVerticalLength(String length)

Parse y axis length value.

Parameters:

length - String length for parsing

Returns:

absolute length in points

applyTransform

void applyTransform(double[] points)
