layout
Description copied from class:BlockRenderer
This method simulates positioning of the renderer, including all of its children, and returns theLayoutResult
, 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
usesTextLayoutResult
as its result. This method can be called standalone to learn how much area the renderer subtree needs, or can be called beforeIRenderer.draw(DrawContext)
, to prepare the renderer to be flushed to the output stream.- Specified by:
-
layout
in interfaceIRenderer
- Overrides:
-
layout
in classBlockRenderer
- Parameters:
-
layoutContext
- the description of layout area and any other additional information - Returns:
- result of the layout process
-
draw
Description copied from class:AbstractRenderer
Flushes the renderer subtree contents, i.e. draws itself on canvas, adds necessary objects to thePdfDocument
etc.- Specified by:
-
draw
in interfaceIRenderer
- Overrides:
-
draw
in classBlockRenderer
- Parameters:
-
drawContext
- contains thePdfDocument
to which the renderer subtree if flushed, thePdfCanvas
on which the renderer subtree is drawn and other additional parameters needed to perform drawing
-
getNextRenderer
Description copied from class:DivRenderer
Gets a new instance of this class to be used as a next renderer, after this renderer is used, ifBlockRenderer.layout(LayoutContext)
is called more than once.If a renderer overflows to the next area, iText uses this method to create a renderer for the overflow part. So if one wants to extend
DivRenderer
, one should override this method: otherwise the default method will be used and thus the default rather than the custom renderer will be created.- Specified by:
-
getNextRenderer
in interfaceIRenderer
- Overrides:
-
getNextRenderer
in classDivRenderer
- Returns:
- new renderer instance
-
createSplitRenderer
Description copied from class:BlockRenderer
Creates a split renderer.- Overrides:
-
createSplitRenderer
in classBlockRenderer
- Parameters:
-
layoutResult
- the result of content layouting - Returns:
-
a new
AbstractRenderer
instance
-
createOverflowRenderer
Description copied from class:BlockRenderer
Creates an overflow renderer.- Overrides:
-
createOverflowRenderer
in classBlockRenderer
- Parameters:
-
layoutResult
- the result of content layouting - Returns:
-
a new
AbstractRenderer
instance
