ScroogeXHTML for Delphi is a library which can convert a subset of the RTF standard to XHTML and HTML5. It is compatible with Delphi 2009+ and Free Pascal 3.0.
Version 6.14 introduces support for paragraph background colors and paragraph box borders. It also fixes Free Pascal warnings and Unicode character conversion.
