The method TWinControl.PaintTo doesn't refresh the RawImage.Data, like
it is done in TRasterImage.Draw. It isn't only a issue for the method
GetFormImage. I fixed it in revision 53790. As far as I can see, there
are no additional calls done, as the needed one (e.g.

Just adding a line to GetFormImage does the trick:
function TForm1.GetFormImage: TBitmap;
var
ARect: TRect;
begin
R

That's a good idea. The current behavior is confusing.

Please try this:
var
bmp: TBitmap;
begin
bmp:=Form1.GetFormImage;
try
*bmp.Canvas.Changed;*
bmp.SaveToFile(ExtractFilePath(Application.ExeName)+'form.bmp');
finally
FreeAndNil(bmp);
end;
end;
But Delphi does not require the bmp.Canvas.Changed. Shouldn't it be
added to the GetFormI
It worked. Thanks!
Why is necessary to call the TCanvas.Changed after TForm1.GetFormImage?

Please try this:

finally

Hi!
Currently I'm trying to use TForm.GetFormImage method to make a minimap
(something similar to Sublime Text editor) of a big form (the parent of
this big form is a TScrollbox on this application).
But, using Qt or GTK2, Lazarus 1.6.3 or trunk, I got the same black bitmap.
So, I created a empt
