This example shows how a SCAN GQE is read from a disk file.
#!/usr/bin/perl
use Spectra;
use GQE;
cls();
#
# read t1.fio and name it t2
#
$t1 = SCAN->read( format => "fio",
name => "t2",
file_name => "t1.fio") or
die " Failed to read t1.fio";
#
# set the viewports and colours
#
$t1->set( at => "(2,2,1)", colour => "red");
Spectra::autoscale();
Spectra::display();
#
#
#
$t1 = SCAN->write( "file_name" => "t2.fio") or
die " Failed to create t2.fio";
#
# cleanup
#
$t1->delete();
