Teechart memory leak when writing PDF?

Hi,
I have added PDF export to my list of exported chart format and notice that there seems to be a memory leak with OffsetList - see below. Is it the way I'm using it or do I see OffsetList is not being freed, only cleared in Destroy?
Regards,
Brian

constructor TTeePDFPage.Create;
begin
inherited Create;
IObjCount := 0;
FChartObject := TPDFChartObject.Create;
OffsetList := TStringList.Create;
end;

destructor TTeePDFPage.Destroy;
begin
FChartObject.Free;
OffsetList.Clear;
inherited;
end;

Hi Pep,

Sorry to have taken so long to reply. I dont have a clean and simple chart to give you to demo the problem, but am I being naieve? Surely OffsetList is never Free'd anywhere? I entered OffsetList.Free in Destroy and the problem goes away fine.

Does this help?
Regards,
Brian

Hi Brian,

yes, this could be the cause, I'll review and change in the sources.
Thanks!.
