The seach selects the found string.
Call ApplyTextStyle or ApplyStyleConversion to change the selection font.
A simple example can be found in Demos\Delphi\MultiDemo\, the last subdemo.

Should it be an editing operation (that can be undone/redone by user)? If not, the code is below: procedure DeleteBlankLines(RVData: TCustomRVData); var i,r,c: Integer; table: TRVTableItemInfo; begin for i := RVData.ItemCount-1 downto 0 do if RVData.IsParaStart(i) and (RVData.GetItemStyle(i)>=0) and...

Well, really?

It's not so hard to make a "quick and dirty" solution for this problem.
So, if you are satisfied with other TRichView feature, consider this function done

Yes, this is a limitation of the current version of TRichView.
I plan to fix it in very near future

Unfortunately, it's not so trivial.

OnSaveRTFExtra can be used to save plain text headers, or headers with some simple formatting.

Saving arbitrary TRichView document as RTF header is not possible in the current version.

It's included in the main set of demos, for example in http://www.trichview.com/rvfiles/rvhelp.zip The directrory inside this zip is Demos\Addins\ChartItem\ It does not provide RTF saving of charts, but I can modify it to save them as pictures, it's very easy. But they will not be loaded as TCharts ...

HTML does not support complex numbering.

It's only possible to export it as a text (and MS Word does it).
TRichView can do it too: include rvsoMarkersAsText in Options of SaveHTML/SaveHTMLEx

RVPrint.TransparentBackground affects only the background color.
To remove the bitmap, call
RVPrint.rv.BackgroundBitmap := nil
after calling AssignSource.

If this problem can be reproduced, I think the simplest way to find the bug is logging a sequence of undo operations - when they were added, grouped, executed. I'll add this log feature in the next update (I'll try to upload it tomorrow)

Well, really, on RTF import, TRichView adds the file path to relative links. In the next update for registered users (I hope to upload it today) I'll add a new property TRichView.RTFReadProperties.BasePathLinks: Boolean. It will work like the corresponding option of RVHtmlImporter - when set to Fals...

TRVColorMode type is defined in the Rvstyle unit.
Probably the problem is again with the headers.

DocRoot is taken from the XML tree:

DocRoot := MainRoot.Items[MainRoot.Items.Count-1];

No, it's not normal, SetHeader() is a public method of TRVPrint, and it must be in PtblRV.hpp. I checked the header included in the trial version, it's there: void __fastcall SetHeader(Crvfdata::TCustomRVFormattedData* RVData); May be you have duplicated HPP files (HPP files of older version of TRic...

Which format do you use to store files? When saving to RVF, tags (where hyperlinks are stored) are not modified.
If you save to HTML and use RvHtmlImporter to read them, it has Options for full/relative paths.
