JPEG-AddOn for Rave 7.7 and Delphi 2010

The christmas-vacation is a good time to look into Delphi 2010 & Rave 7.7 BE and try to create an update of the AddOn from Rave Reports. I started with the JPEG-AddOn and I remembered that the VCLJPG-package is changed since 2009 because Embarcadero adds new GIF and PNG-format. Here you'll find a beta-version of the JPEG-AddOn for Rave 7.7 and Delphi 2010 for testing (and using, on your own risk, of course). Thx for a feedback if it works in your environment..

    If I compile for XE6 / Rave 11 no components appear in Rave even thought the package appears in the list? Has anyone had luck with Rave 11?

    @Tristan Marlow: I've compiled in the meantime nearly all AddOns and will publish the Rave11 version in the next weeks here on the blog.

    Thanks Thomas, I have worked around it for now by changing LoadFromStream in RvCsStd for TRaveGraphicImage.

    Uses a TWICImage to convert the stream. http://docwiki.embarcadero.com/Libraries/XE6/en/Vcl.Graphics.TWICImage

    This may only work Delphi 2010 upwards.

    procedure TRaveGraphicImage.LoadFromStream(Stream: TStream);
    var
    WicImage: TWICImage;
    begin { LoadFromStream }
    UnloadAltImage;
    FAltImage := CreateGraphic;

    // Use new TWICImage to convert images.
    WicImage := TWICImage.Create;
    try
    WicImage.LoadFromStream(Stream);
    FAltImage.Assign(WicImage);
    finally
    FreeAndNil(WicImage);
    end;

    // FAltImage.LoadFromStream(Stream);

    if not ImageValid then
    begin { Invalid image format }
    UnloadAltImage;
    end; { if }
    end; { LoadFromStream }
