SimpleTextExtractingPdfContentRenderListener (iText, a Free Java-PDF library 4.2.0 API)

java.lang.Object
- com.itextpdf.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
