# To subscribers of the xforms list from "T.C. Zhao" <tc_zhao@yahoo.com> :
Can't see obvious errors from the code below except
that you should not be setting image->display_type, which
is not meant to be used by the application. One of these
days, I'll make an opaque structure to hold all of these
internal variables.
If punting setting image->display_type does not help,
try to comment out the add_text() and postscript dump and
see if it displays correctly.
