TRVHtmlImporter can still only import CSS saved by RichView.SaveHTMLEx.
But the new importer was developed: TRVHtmlViewImporter. It uses the components from
http://www.pbear.com (they are freeware with source code).
TRVHtmlViewImporter is here:
http://www.trichview.com/resources/html ... import.zip (free with source code too).
Before installing the PBear's components and this importer, please read ReadMe.txt from rvhtmlviewimport.zip.
TRVHtmlViewImporter requires the latest version of TRichView, available for registered users. If you want to use it with older (for example, trial) version, open rvHtmlViewImport.pas and remove the line:
{$DEFINE RVFULL}
