createColor
public Color createColor(SvgDrawContext context, Rectangle objectBoundingBox, float objectBoundingBoxMargin, float parentOpacity) Description copied from interface:ISvgPaintServer
Creates theColor
that represents the corresponding paint server for specified object box.- Parameters:
context
- the current svg draw contextobjectBoundingBox
- 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
Description copied from interface:ISvgNodeRenderer
Creates a deep copy of this renderer, including it's subtree of children- Specified by:
createDeepCopy
in interfaceISvgNodeRenderer
- Specified by:
createDeepCopy
in classAbstractBranchSvgNodeRenderer
- Returns:
- deep copy of this renderer
-
getObjectBoundingBox
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
