Memory Leak GDI+

[José Araújo]

I'd removed the line IXORCanvas:=TTeeCanvas3D.Create from InitWindow and put in the Constructor Create and trouble keep on.
What should I do now? Any solve else?

I'd sent a print screen from MM4.

thanks

Hi Fausto,

Why do you want to remove that line? We added it to fix these memory leaks.

I´m using the >>>TeeChart Pro 2010 Full Source Code >>>Version 0.4455.0.0 and like you can see the Memory Leak keep on. Have you see the atachment file (print mm4) wich I sent you?

Hi Fausto,

You may be doing something different than me. Here is what I'm doing:

Code: Select all

uses Series, TeeGDIPlus;

procedure TForm1.FormCreate(Sender: TObject);
var FGDIPlus: TTeeGDIPlus;
begin
  with Chart1.AddSeries(TBarSeries) as TBarSeries do FillSampleValues();

  FGDIPlus := TTeeGDIPlus.Create(Self);
  FGDIPlus.TeePanel := Chart1;

  ReportMemoryLeaksOnShutdown := True;
end;

Could you please modify the example above so we can reproduce the error here?

[José Araújo]

If you change the transparency of the WALLS you can memory on. In your example you forgot put the GDIPlus (Active = True).
I'd attached other example. I my example you should use the ROTATE TOOL and you can see the memory usage UP and UP UP UP UP.

In transparency in SERIES I´d found problems too

Hi Fausto,

I my example you should use the ROTATE TOOL and you can see the memory usage UP and UP UP UP UP.

So it's with most probability related with the problem discussed here and here (TV52014993). It has been already fixed for the next maintenance release.
I could reproduce the problem with the latest published version but with the actual sources it seems to work fine.

In transparency in SERIES I´d found problems too

Could you please explain us how can we reproduce it?

[José Araújo]

When the next release will be available? I nedd this urgently.

Here the problem has been reproduced with the code:

///////////////////////////////////////////////////////////////////////////
uses
Series, TeeGDIPlus;

procedure TForm1.FormCreate(Sender: TObject);
var
FGDIPlus: TTeeGDIPlus;
begin
with Chart1.AddSeries(TBarSeries) as TBarSeries do FillSampleValues();

TBarSeries(Chart1.Series[0]).Transparency := 50; // THIS LINE INVOKE MEMORY LEAK (USE ROTATE TOOL TO SEE MEMORY USAGE UP UP...)

FGDIPlus := TTeeGDIPlus.Create(Self);
FGDIPlus.TeePanel := Chart1;
FGDIPlus.Active:=true;
end;

Hi Fausto,

As you are source code customer, I've sent the actual sources to the mail you have registered in this forums.
Could you please check if they correct the problem?

[José Araújo]

Could you re-send me the email? I changed my email because the older was written wrong.
Apologies!!!

Hi Fausto,

Just done!

[José Araújo]

Yeray,

Thanks a lot buddy. Now, it's stable. And my boss is very happy.

Thankful,
Fausto Jr.
