Re: Problem with RVPrint and PDF export

1) Sorry, I do not understand what's the problem with the preview dialog, because this dialog does not allow copying text. 2) In the new demo, margins are loaded from files (RVF or RTF). After loading: FDocument.MainDoc.RichView.LoadRTF(FileName) , margins are loaded in FDocument.MainDoc.RichView.Do...

Re: Problem with RVPrint and PDF export

By default, TRichView, TRVPrint and TRVReportHelper use an advanced text drawing method, which draws text using indexes of character glyphs (indexes of character images in fonts) instead of character codes. This method is the best for drawing multilanguage texts, and it must not cause problems in dr...

Re: RVCamera

In the next update, I'll add a new event to TRVCamRecorder: OnFirstFrame. It will occur after recording the first video frame. You will be able to stop the previous recorder after this event in the new recorder.

But when the first frame is received, it restarts recording with the frame size (and updates VideoWidth and VideoHeigh...

But I'll try to investigate further...

Re: How to save fixed length video files

We never tested TRVCamRecorder in this mode, so this is not a simple question. I'll try to answer till the end of this week. Sorry for the delay.
