public interface ISvgNodeRenderer

Interface for SvgNodeRenderer, the renderer draws the SVG to its Pdf-canvas passed in SvgDrawContext, applying styling (CSS and attributes).

Method Detail

setParent

void setParent(ISvgNodeRenderer parent)

Sets the parent of this renderer. The parent may be the source of inherited properties and default values.

Parameters:

parent - the parent renderer

getParent

ISvgNodeRenderer getParent()

Gets the parent of this renderer. The parent may be the source of inherited properties and default values.

Returns:

the parent renderer; null in case of a root node

draw

void draw(SvgDrawContext context)

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

Parameters:

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

setAttributesAndStyles

void setAttributesAndStyles(java.util.Map<java.lang.String,java.lang.String> attributesAndStyles)

Sets the map of XML node attributes and CSS style properties that this renderer needs.

Parameters:

attributesAndStyles - the mapping from key names to values

getAttribute

java.lang.String getAttribute(java.lang.String key)

Retrieves the property value for a given key name.

Parameters:

key - the name of the property to search for

Returns:

the value for this key, or null

setAttribute

void setAttribute(java.lang.String key,
                  java.lang.String value)

Sets a property key and value pairs for a given attribute

Parameters:

key - the name of the attribute

value - the value of the attribute

getAttributeMapCopy

java.util.Map<java.lang.String,java.lang.String> getAttributeMapCopy()

Get a modifiable copy of the style and attribute map

Returns:

copy of the attributes and styles-map

createDeepCopy

ISvgNodeRenderer createDeepCopy()

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

Returns:

deep copy of this renderer

getObjectBoundingBox

Rectangle getObjectBoundingBox(SvgDrawContext context)

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
