This method simulates positioning of the renderer, including all of its children, and returns the iText.Layout.Layout.LayoutResult , representing the layout result, including occupied area, status, i.e. if there was enough place to fit the renderer subtree, etc. iText.Layout.Layout.LayoutResult can be extended to return custom layout results for custom elements, e.g. TextRenderer uses iText.Layout.Layout.TextLayoutResult as its result. This method can be called standalone to learn how much area the renderer subtree needs, or can be called before Draw(DrawContext) , to prepare the renderer to be flushed to the output stream.
layoutContext | the description of layout area and any other additional information |
Implements iText.Layout.Renderer.AbstractRenderer.
Reimplemented in iText.Layout.Renderer.ParagraphRenderer, iText.Layout.Renderer.ListItemRenderer, iText.Layout.Renderer.ListRenderer, and iText.Layout.Renderer.LineSeparatorRenderer.
