17 Example:
18 ~~~ {.cpp}
19  $ root -b
20  root [0] .x hsimple.C
21  root [1] c1->Print("c1.gif");
22 ~~~
23 TImageDump can be used in any mode (batch, interactive) as follows
24 ~~~ {.cpp}
25  TCanvas *c1;
26  TImageDump *imgdump = new TImageDump("test.png");
27  c1->Paint();
28  imgdump->Close();
