    • layout

      public 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. 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.
      Parameters:
      layoutContext - the description of layout area and any other additional information
      Returns:
      result of the layout process

    • move

      public void move (float dxRight, float dyUp)
      Moves the renderer subtree by the specified offset. This method affects occupied area of the renderer.
      Specified by:
      move in interface IRenderer
      Overrides:
      move in class AbstractRenderer
      Parameters:
      dxRight - the x-axis offset in points. Positive value will move the renderer subtree to the right.
      dyUp - the y-axis offset in points. Positive value will move the renderer subtree to the top.

    • draw

      public void draw (DrawContext drawContext)
      Flushes the renderer subtree contents, i.e. draws itself on canvas, adds necessary objects to the PdfDocument etc.
      Specified by:
      draw in interface IRenderer
      Overrides:
      draw in class AbstractRenderer
      Parameters:
      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

    • getMinMaxWidth

      public MinMaxWidth getMinMaxWidth()
      Calculates min and max width values for current renderer.
      Overrides:
      getMinMaxWidth in class AbstractRenderer
      Returns:
      instance of MinMaxWidth

    • getMinMaxWidth

      public MinMaxWidth getMinMaxWidth (Float parentBoxWidth)
      Calculates min and max width values for current renderer.
      Overrides:
      getMinMaxWidth in class AbstractRenderer
      Parameters:
      parentBoxWidth - max width of the area on which current renderer will be laid out
      Returns:
      instance of MinMaxWidth

    • getNextRenderer

      public 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.
      Returns:
      new renderer instance

    • getFirstYLineRecursively

      protected Float getFirstYLineRecursively()
      Gets the first yLine of the nested children recursively. E.g. for a list, this will be the yLine of the first item (if the first item is indeed a paragraph). NOTE: this method will not go further than the first child.
      Overrides:
      getFirstYLineRecursively in class AbstractRenderer
      Returns:
      the first y line of the nested children, null if there is no text found

    • getLastYLineRecursively

      protected Float getLastYLineRecursively()
      Overrides:
      getLastYLineRecursively in class AbstractRenderer
