Method Detail

createColor

public com.itextpdf.kernel.colors.Color createColor(SvgDrawContext context,
                                                    com.itextpdf.kernel.geom.Rectangle objectBoundingBox,
                                                    float objectBoundingBoxMargin,
                                                    float parentOpacity)

Description copied from interface: ISvgPaintServer

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

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

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

getObjectBoundingBox

public com.itextpdf.kernel.geom.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

isHidden

protected boolean isHidden()

Description copied from class: AbstractSvgNodeRenderer

Check if this renderer should draw the element based on its attributes (e.g. visibility/display)

Overrides:

isHidden in class AbstractSvgNodeRenderer

Returns:

true if element won't be drawn, false otherwise
