原始的东西是什么,在Canvas上面吗?
有个打印网页的例子,可以参考一下

procedure TForm1.Button1Click(Sender: TObject);
var
do
c: IHTMLDocument2;
ViewObject: IViewObject;
sourceDrawRect: TRect;
a, getjpg: TBitMap;
i, m: integer;
pdest, psour: hbitmap;
jpg: tjpegimage;
begin
do
c := WebBrowser.Document as IHTMLDocument2;
if Webbrowser.Document <> nil then
try
webbrowser.Document.QueryInterface(IViewObject, ViewObject);
if ViewObject <> nil then
try
do
c.Get_ParentWindow.Scroll(0, 0);
//跳到网页头
getjpg := TBitMap.Create();
getjpg.PixelFormat := pf24bit;

c.Body.getAttribute('scrollHeight', 0);

end;

finally
ViewObject._Release;
end;
except
end;
end;
