Yes.
If you use Delphi 2007 or newer, include RVGifAnimate2007 unit in your project
(for older versions, you need to use third-party gif classes)

Also, you can change RichViewEdit.AnimationMode to rvaniOnFormat to start animation automatically.

I confirm the problem: if you set cxrv.Properties.Properties.AnimationMode = rvaniOnFormat at designtime, it does not work.

Fix: open cxTRichView.pas, find procedure TcxCustomTRichViewEdit.Loaded, change it to:

Code: Select all

procedure TcxCustomTRichViewEdit.Loaded;
begin
  inherited;
  ShortRefreshContainer(False);
  if InnerEditor <> nil then
    InnerEditor.Loaded;
end;
This fix will be included in the next update.

How do you load the image? The animation is supported if it is loaded as TGifImage, not as DevExpress graphic class (TdxSmartImage)


If you load a gif file using TPicture.LoadFromFile or RVGraphicHandler.LoadFromFile, the most probably, the image is loaded as TdxSmartImage.

You can unregister TdxSmartImage by calling
TPicture.UnregisterGraphicClass(TdxSmartImage);
when the application starts (include dxGDIPlusClasses in "uses").

Thanks TPicture.UnregisterGraphicClass(TdxSmartImage); Works !

Also in some cases can help moving declaration of dx*** units before:
GifImg, RVGifAnimate2007
