Flushes the renderer subtree contents, i.e.

getOccupiedAreaBBox()
Gets the bounding box that contains all content written to the DrawContext by this IRenderer .
|
LayoutResult |
layout(LayoutContext layoutContext)
This method simulates positioning of the renderer, including all of its children, and returns the LayoutResult , representing the layout result, including occupied area, status, i.e.

protected BlockRenderer(IElement modelElement)
public LayoutResult layout(LayoutContext layoutContext)
IRenderer
LayoutResult
, representing the layout result, including occupied area, status, i.e. if there was enough place to fit the renderer subtree, etc. LayoutResult
can be extended to return custom layout results for custom elements, e.g. TextRenderer
uses TextLayoutResult
as its result. This method can be called standalone to learn how much area the renderer subtree needs, or can be called before IRenderer.draw(DrawContext)
, to prepare the renderer to be flushed to the output stream.
layoutContext
- the description of layout area and any other additional information
protected AbstractRenderer createSplitRenderer(int layoutResult)
protected AbstractRenderer createOverflowRenderer(int layoutResult)
public void draw(DrawContext drawContext)
AbstractRenderer
PdfDocument
etc.
draw
in interface IRenderer
draw
in class AbstractRenderer
drawContext
- contains the PdfDocument
to which the renderer subtree if flushed, the PdfCanvas
on which the renderer subtree is drawn and other additional parameters needed to perform drawing
public Rectangle getOccupiedAreaBBox()
AbstractRenderer
DrawContext
by this IRenderer
.
getOccupiedAreaBBox
in class AbstractRenderer
Rectangle
that surrounds the content
protected void applyVerticalAlignment()
protected void applyRotationLayout(Rectangle layoutBox)
@Deprecated protected float[] applyRotation()
protected AffineTransform createRotationTransformInsideOccupiedArea()
AffineTransform
instance that could be used to rotate content inside the occupied area. Be aware that it should be used only after layout rendering is finished and correct occupied area for the rotated element is calculated.
AffineTransform
that rotates the content and places it inside occupied area.
