This property select the format used by the properties Text and Text2. You can use the strings "ANSI", "RTF", "HTML" to select the major file formats but also "UNICODE" and "WPT". The WPT format is our proprietary fileformat which is also used by the product WPTools.
If not format or "AUTO" was specified the reading process will check the format automatically, this works for RTF, HTML and WPT format. All other text will be loaded as ANSI.
After the name of the format options are possible, for example "RTF-ignorepagesize". See http://www.wpcubed.com/manuals/formatstr.htm.
