Hi,

it seems there is a memory leak when using TTeeGDIPlus. It can be reproduced in the sample project (Delphi 2010) I've attached.
Just run the code and then resize the form a couple of times and then close it. I've also attached a screenshot of the FastMM report that pops up.

I think it's caused by TGDIPlusCanvas.InitWindow() which is called by the draw routine.

It creates a TTeeCanvas3D object each time it is called but doesn't free it
...
begin
IXORCanvas:=TTeeCanvas3D.Create;

Could you please take a look at it?

Regards,
Amadeus

While I'm at it: seems there's another one in Chart.pas ->TLegendSymbol.Draw()

OldBrush:=TBrush.Create;

OldBrush doesn't get freed.

Hi Amadeus,

You are right. I could reproduce it so I've added it to the defect list to be revised in future releases (TV52014961).
Thanks for reporting it.

Yes, we found that some weeks ago and fixed it for the next maintenance release.

Hi Amadeus,

Just wanted to let you know that TV52014961 has been fixed for the next maintenance release. To fix this you can add line below to GDI+ canvas constructor (TGDIPlusCanvas.Create) and remove it from TGDIPlusCanvas.InitWindow.

Yes, this does the trick.
Thanks for the quick help. It's appreciated

Kubach,

You're very welcome. Thanks for your feedback too!
