Annotation and ChartFX

[User (Legacy)]

Hi,

I'm using Delphi 2005 with ChartFX and the Annotation extension to add a 

couple of JPG images to a chart.  However, I want to be able to load the 

images from a database, a resource or a control rather than the actual 

picture file itself.  I have been unable to find a way of doing this - there 

only seems to be the option to LoadFromFile.

Is there a way I can create a Picture object without referencing a filename?

Thanks in advance!

Assuming you are using .NET and Chart FX 6.x:

The annotation picture class has a Picture property of type 

System.Drawing.Image, this allows you to assign an image object that you 

have previously loaded (from your DD, file, etc.)

If you are using the COM version (Chart FX 5.x):

Similar except that the Picture property is of type TPicture instead.

Hi Francisco,

Have tried using Picture but can't seem to get it to display.  I'm loading 

it from a stream ( have checked it by loading it into a Timage as well and 

it does that fine).  Here's my code - would you mind having a look and 

seeing if I've missed something?

var

  annotPic : AnnPicture;

  AnnotX: AnnotationX;

  aPic : TBitmap;

  AnnotX := AnnotationX.Create;

  ChartFXCS1.AddExtension(AnnotX.InterfacePtr);

  AnnotX.ToolBarObj.Visible := false;

  annotPic := AnnPicture.Create(AnnotX.Add(OBJECT_TYPE_PICTURE,0));

  aPic := Tbitmap.Create;

    if LoadAPicResource(PicStream,'BMP') then                    // this 

returns a resource stream via PicStream - this part works!

    begin

      aPic.LoadFromStream(PicStream);

      annotPic.Picture.Assign(aPic);

    end;

Have also tried loading directly using   :- 

annotPic.Picture.Bitmap.LoadFromStream(PicStream);

and also tried using TPicture instead of TBitmap.

Nothing seems to work, and I'm left with a blank dotted outline on the chart 

where the picture should be.

Any thoughts?
