Since the code calling the function wants to use the bitmap, it MUST free it NOT your
function.
> function Tcamform.SizeFunc(BMap: Tbitmap): Tbitmap;
> var
> BMPtmp, BMPtmpB: TFastBMP;
> TempBMP: Tbitmap;
> wsize, hsize: word;
> fval1, fval2: single;
> begin
> // A whole lotta code goes here
> BMPtmpB := TfastBMP.CreateFromhBmp(BMap.handle); // Like a bitmap
1st Object Created
> BMPtmp := TfastBMP.Create(wsize, hsize);
2nd Object Created
> TempBMP := Tbitmap.Create;
3rd Object Created
> try
> TempBMP.Width := wsize;
> TempBMP.Height := hsize;
> BMPtmpB.SmoothResize(BMPtmp);
> BMPtmp.Draw(TempBMP.canvas.handle, 0, 0);
Ummm... This is drawnig TempBMP onto BMTTmp but neither one
have anything on them since they were _just_ created. ?
> result := TempBMP;
Result now POINTS to the 3rd Object
> finally
> begin
> TempBMP.FreeImage; // If I'm free then result=nil
I'm not sure this is what you're wanting to do.
This releases the memory image of the 3rd Object created
which is also the object pointed to by Result
> BMPtmp.Free;
Second Object freed
> BMPtmpB.Free;
1st Object freed
> end;
> end;
> end;
