ROOT canvas save problem

At first I could not save the ROOT plots, error mesg
Error in <tunixsystem::dynamicpathname>: Postscript[.so | .dll | .dylib | .sl | .dl | .a] does not exist in <tunixsystem::dynamicpathname> ...

Then found this discussion about this very same issue.

sudo apt-get install libroot-graf2d-postscript5.34

Solved.

Now I can save as png or pdf / ps etc. But not gif. Error,
Error in <tasimage::writeimage>: error writing file

But pdf and png are fine for now :)
