Constructor and Description |

ImageRenderer(Image image)
Creates an ImageRenderer from its corresponding layout object.

Modifier and Type | Method and Description |
---|---|
protected ImageRenderer |
autoScale(LayoutArea area) |
void |
draw(DrawContext drawContext)
Flushes the renderer subtree contents, i.e.
|
IRenderer |
getNextRenderer()
Gets a new instance of this class to be used as a next renderer, after this renderer is used, if IRenderer.layout(LayoutContext) is called more than once.
|
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.

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
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 IRenderer getNextRenderer()
IRenderer
IRenderer.layout(LayoutContext)
is called more than once.
