Why don't you post your simple example? Then we can see what you might be
doing wrong. At this point all you want to do is texture map a polygon with
an image containing an alpha channel. Your example should only be 5 or so
lines. Use XOBJVIEW to display it.

As for examples, I don't know of any in the IDL distribution. I know this
has been covered in depth before in this group. You could use google to
search the archives.
