15\brief Save canvas as an image (GIF, JPEG, PNG, XPM, TIFF etc.).
16
17Example:
18~~~ {.cpp}
19 $ root -b
20 root [0] .x hsimple.C
21 root [1] c1->Print("c1.gif");
22~~~
23TImageDump 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();
