Constructor Details

PatternSvgNodeRenderer

public PatternSvgNodeRenderer()

Method Details

createDeepCopy

public ISvgNodeRenderer createDeepCopy()

Description copied from interface: ISvgNodeRenderer

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

Specified by:

createDeepCopy in interface ISvgNodeRenderer

Specified by:

createDeepCopy in class AbstractBranchSvgNodeRenderer

Returns:

deep copy of this renderer

createColor

public Color createColor(SvgDrawContext context,
 Rectangle objectBoundingBox,
 float objectBoundingBoxMargin,
 float parentOpacity)

Description copied from interface: ISvgPaintServer

Creates the Color that represents the corresponding paint server for specified object box.

Specified by:

createColor in interface ISvgPaintServer

Parameters:

context - the current svg draw context

objectBoundingBox - the coloring object bounding box without any adjustments (additional stroke width or others)

objectBoundingBoxMargin - the objectBoundingBoxMargin of the object bounding box to be colored (for example - the part of stroke width that exceeds the object bounding box, i.e. the half of stroke width value)

parentOpacity - current parent opacity modifier

Returns:

the created color

getObjectBoundingBox

public Rectangle getObjectBoundingBox(SvgDrawContext context)

Description copied from interface: ISvgNodeRenderer

Calculates the current object bounding box.

Specified by:

getObjectBoundingBox in interface ISvgNodeRenderer

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
