Anti-aliasing is not supported in direct graphics. Everything is either
"pixel on" or "pixel off." There's no gray* area to allow for AA.

* = pun intended.

Object graphics won't work if you're tied to any direct graphics
routine, MAP_* or otherwise.

Not really. You just have to run your entire program and then just do a
quick command on the system to see the file. It's just one additional
line to type in. For example,

IDL> create_me_plot, data, FILENAME="myfile.ps"
IDL> $display myfile.ps

Of course, I'm assuming that the stated command creates a file for you.
And I'm also assuming that you're using an operating system that
allows you to quickly go to a command line like that. ;-)
