Re: TRVReportHelper DrawPage do not draw "page header"

TRVReportHelper does not support headers, footers, footnotes, endnotes, sidenotes and text boxes. There are some examples using separate TRVReportHelpers for the main document and for headers and footers , but still they do not support notes, do not support all types of headers and footers, and do n...

Re: RichViewImportPicture - load Pictures from Web (emails)

You download picture in Graphics, and then delete this Graphic.
Remove the lines:

Code: Select all

Graphic.Free;
Graphic := nil;

Re: Need your advance

Do not create list marker items directly.
Use SetListMarkerInfo instead. If ItemNo parameter = -1, this method adds maker to the end of document.

Re: Are you interested in Lazarus version of TRichView?

Thank you! I do not plan to sell Lazarus version separately. May be in future, when not only Windows platform will be supported... You will be able to install the next update of TRichView both in Delphi and Lazarus from the same source code. Current progress: - normal and DB TRichView components are...

Re: Are you interested in Lazarus version of TRichView?

Yesterday I finally managed to compile TRichView in Lazarus, almost without hints and warnings. Lazarus-TRicView.png I still need to complete printing support and to test everything. Things that are not converted: - gif animations - metafiles (they are important for working with RTF and DocX) - GDI+...

Re: Try connect D-LINK DCS-931L

Unfortunately, this is a local IP address, so we cannot test it ourselves.

Which version of RVMedia do you use? Do you have FFmpeg available for this application?

Re: Image matting Filter

RVMedia does not include image filters. The demo in Cameras\Filters\ implements some filters, but they are implemented in this demo, not in RVMedia itself. The demo processes TRVCamView.OnPaint and modifies a bitmap that will be displayed. If you implement your own filter (or use a function from a t...

Re: [Demo] Storing TRichView using Synopse mORMot framework (SQLite3)

1. The actual document is stored in RVF format, which is binary format, and it is stored in BLOB field. I am afraid it is not possible to search for text in BLOB fields (especially considering the fact that it contains not only text but images, font properties, control codes, etc.). So I think a pla...
