Is TASImage streamable?

ROOT

Is the TASImage class meant to be streamed to/from a file?

When I try to read this class back from a file which I saved one to, it doesn’t have the image information anymore. For example, the TASImage::Draw() command won’t work on the streamed-in object.

Here’s a simple example:

gSystem->Load("$ROOTSYS/lib/libASImage.so")
TASImage i("$ROOTSYS/tutorials/rose512.jpg")
i.SetName("rose")
i.Draw()
TFile f("test.root","RECREATE")
i.Write()
f.Close()

Then, when you try to read it in a different root session,

gSystem->Load("$ROOTSYS/lib/libASImage.so")
TFile f("test.root")
f.ls()
rose.Draw()

 *** Break *** bus error

This is with ROOT version 4.04/02 on Mac OS X.

Should I just not try to save these objects to a file, or am I doing something wrong?

Thanks,

TASimage persistence was only implemented in version 5.02
