# TXIMAGE -- Extract image from 3D table row.
# Input tables are given by a filename template list. All row/column
# selection on input tables is performed by bracket-enclosed selectors
# appended to the file name. The output is either a matching list of
# images or a directory. Since one input table specification can generate
# multiple output images, a naming scheme for these is defined as follows:
#
# - if output name is a directory:
# output image names are built from input table names appended with
# a _rXXX suffix, where XXX is the row number in the input file
# where the data comes from.
#
# - if output image name comes from a paired root file name list:
# same suffixing scheme as above, but using the root file name
# extracted from the list.
#
# - if only one row is selected:
# no suffixing takes place.
#
#
# This code is a re-use of B.Simon's 04-Nov-94 version of tcopy.
#
#
#
# Revision history:
# ----------------
#
# 26-Nov-96 - Task created (I.Busko)
# 03-Jan-97 - Revised after code review (IB)
