T1

GetFirstYLineRecursively()

GetLines()

Gets the lines which are the result of the Layout(LayoutContext).

public virtual IList<LineRenderer> GetLines()

Returns

IList<LineRenderer>

paragraph lines, or null if layout hasn't been called yet

GetMinMaxWidth() 

public override MinMaxWidth GetMinMaxWidth()

Returns

GetNextRenderer()

Gets a new instance of this class to be used as a next renderer, after this renderer is used, if Layout(LayoutContext) is called more than once.

public override IRenderer GetNextRenderer()

Returns

IRenderer

new renderer instance

Remarks

Gets a new instance of this class to be used as a next renderer, after this renderer is used, if 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 ParagraphRenderer , one should override this method: otherwise the default method will be used and thus the default rather than the custom renderer will be created.

Parameters

layoutContext LayoutContext

Returns

LayoutResult

public override void Move(float dxRight, float dyUp)
