This filter is similar to the plain RtfFilter, except if generates RTF fields with absolute positioning. The resulting files are more accurate than the ones created with the plain RTF filter, but they are harder to edit and can only be opened in Microsoft Word (WordPad and other simple editors do not support RTF absolute positioning).

Creating an RtfLabelFilter and using it in a call to the RenderToFilter(ExportFilter) method is similar to using the RenderToFile(String, FileFormatEnum) or RenderToStream(Stream, FileFormatEnum) methods, but offers some extra flexibility because you can set properties on the RtfLabelFilter before calling RenderToFilter.
