Constructor Details

EllipseSvgNodeRenderer

public EllipseSvgNodeRenderer()

Method Details

doDraw

protected void doDraw(SvgDrawContext context)

Description copied from class: AbstractSvgNodeRenderer

Draws this element to a canvas-like object maintained in the context.

Specified by:

doDraw in class AbstractSvgNodeRenderer

Parameters:

context - the object that knows the place to draw this element and maintains its state

getObjectBoundingBox

public Rectangle getObjectBoundingBox(SvgDrawContext context)

Description copied from interface: ISvgNodeRenderer

Calculates the current object bounding box.

Parameters:

context - the current context, for instance it contains current viewport and available font data

Returns:

the Rectangle representing the current object's bounding box, or null if bounding box is undefined

setParameters

@Deprecated
protected boolean setParameters()

Deprecated.

Fetches a map of String values by calling getAttribute(String s) method and maps it's values to arc parameter cx, cy , rx, ry respectively

This method is deprecated in favour of setParameters(SvgDrawContext), because x/y/rx/ry can contain relative values which can't be resolved without SvgDrawContext.

Returns:

boolean values to indicate whether all values exit or not

setParameters

protected boolean setParameters(SvgDrawContext context)

Fetches a map of String values by calling getAttribute(String s) method and maps it's values to arc parameter cx, cy , rx, ry respectively

Parameters:

context - the SVG draw context

Returns:

boolean values to indicate whether all values exit or not

initCenter

protected void initCenter(SvgDrawContext context)

Initialize ellipse cx and cy.

Parameters:

context - svg draw context

createDeepCopy

public ISvgNodeRenderer createDeepCopy()

Description copied from interface: ISvgNodeRenderer

Creates a deep copy of this renderer, including it's subtree of children

Returns:

deep copy of this renderer

doStrokeOrFill

void doStrokeOrFill(String fillRuleRawValue,
 PdfCanvas currentCanvas)

Description copied from class: AbstractSvgNodeRenderer

Do stroke or fill based on doFill/doStroke fields.

Overrides:

doStrokeOrFill in class AbstractSvgNodeRenderer

Parameters:

fillRuleRawValue - fill rule attribute value.

currentCanvas - current canvas to draw on.
