## com.lowagie.text.pdf.parser
Class SimpleTextExtractingPdfContentRenderListener

    java.lang.Object
      com.lowagie.text.pdf.parser.SimpleTextExtractingPdfContentRenderListener

All Implemented Interfaces:
  RenderListener, TextProvidingRenderListener

    public class SimpleTextExtractingPdfContentRenderListener

extends java.lang.Object
implements TextProvidingRenderListener

A simple text extraction renderer. This renderer keeps track of the current Y position of each string. If it detects that the y position has changed, it inserts a line break into the output. If the PDF renders text in a non-top-to-bottom fashion, this will result in the text not being a true representation of how it appears in the PDF. This renderer also uses a simple strategy based on the font metrics to determine if a blank space should be inserted into the output.

Since:
  2.1.5

Field Summary
`private Vector` | `lastEnd`
`private float` | `lastEndingXPos` keeps track of the X position of the end of the last rendered text
`private Vector` | `lastStart`
`private Matrix` | `lastTextLineMatrix`
`private float` | `lastYPos` keeps track of the Y position of the last rendered text
`private java.lang.StringBuffer` | `result` used to store the resulting String.

Constructor Summary
`SimpleTextExtractingPdfContentRenderListener()` Creates a new text extraction renderer.

Method Summary
`java.lang.String` | `getResultantText()` Returns the result so far.
`void` | `renderText(TextRenderInfo renderInfo)` Captures text using a simplified algorithm for inserting hard returns and spaces
`void` | `reset()` Resets the internal state of the RenderListener
