I find this works best if we enter the pip environment:
and we get better screen grabs if we edit the rigol_grab.py script and change the image format to JPG instead of PNG. However, so far, I cannot get 100% perfect images each time without disconnecting and reconnecting the USB cable.
This is a known bug with this script, and I'm not sure how much time I will spend debugging this at this time.
I was wondering is there something out there for Solaris 7 for screen capture?
Also it would really help if there was some software out there that can record whats happens on the screen for like 10 seconds or how ever long I need it to.
I did a search but doesn't seem to be alot out there. (10 Replies)

io::capture::stdout
IO::Capture::Stdout(3pm) User Contributed Perl Documentation IO::Capture::Stdout(3pm)NAME
IO::Capture::Stdout - Capture any output sent to STDOUT
SYNOPSIS
# Generic example (Just to give the overall view)
use IO::Capture::Stdout;
$capture = IO::Capture::Stdout->new();
$capture->start(); # STDOUT Output captured
print STDOUT "Test Line One
";
print STDOUT "Test Line Two
";
print STDOUT "Test Line Three
";
$capture->stop(); # STDOUT output sent to wherever it was before 'start'
# In 'scalar context' returns next line
$line = $capture->read;
print "$line"; # prints "Test Line One"
$line = $capture->read;
print "$line"; # prints "Test Line Two"
# move line pointer to line 1
$capture->line_pointer(1);
$line = $capture->read;
print "$line"; # prints "Test Line One"
# Find out current line number
$current_line_position = $capture->line_pointer;
# In 'List Context' return an array(list)
@all_lines = $capture->read;
# More useful example 1 - "Using in module tests"
# Note: If you don't want to make users install
# the IO::Capture module just for your tests,
# you can just install in the t/lib directory
# of your module and use the lib pragma in
# your tests.
use lib "t/lib";
use IO::Capture::Stdout;
use Test::More;
my $capture = IO::Capture::Stdout->new;
$capture->start
# execute with a bad parameter to make sure get
# an error.
ok( ! $test("Bad Parameter") );
$capture->stop();
DESCRIPTION
The module "IO::Capture::Stdout", is derived from the abstract class "IO::Capture". See IO::Capture. The purpose of the module (as the
name suggests) is to capture any output sent to "STDOUT". After the capture is stopped, the STDOUT filehandle will be reset to the previ-
ous location. E.g., If previously redirected to a file, when "IO::Capture->stop" is called, output will start going into that file again.
Note: This module won't work with the perl function, system(), or any other operation
involving a fork(). If you want to capture the output from a system command,
it is faster to use open() or back-ticks.
my $output = `/usr/sbin/ls -l 2>&1`;
METHODS
new
o Creates a new capture object.
o An object can be reused as needed, so will only need to do one of these.
o Be aware, any data previously captured will be discarded if a new capture session is started.
start
o Start capturing data into the "IO::Capture" Object.
o Can not be called on an object that is already capturing.
o Can not be called while STDOUT tied to an object.
o "undef" will be returned on an error.
stop
o Stop capturing data and point STDOUT back to it's previous output location I.e., untie STDOUT
read
o In Scalar Context
o Lines are read from the buffer at the position of the "line_pointer", and the pointer is incremented by one.
$next_line = $capture->read;
o In List Context
o The array is returned. The "line_pointer" is not affected.
@buffer = $capture->read;
o Data lines are returned exactly as they were captured. You may want to use "chomp" on them if you don't want the end of line charac-
ter(s)
while (my $line = $capture->read) {
chomp $line;
$cat_line = join '', $cat_line, $line;
}
line_pointer
o Reads or sets the "line_pointer".
my $current_line = $capture->line_pointer;
$capture->line_pointer(1);
SUB-CLASSING
Adding Features
If you would like to sub-class this module to add a feature (method) or two, here is a couple of easy steps. Also see IO::Capture::Over-
view.
1 Give your package a name
package MyPackage;
2 Use this "IO::Capture::Stdout" as your base class like this:
package MyPackage;
use base qw/IO::Capture::Stdout/;
3 Add your new method like this
package MyPackage;
use base qw/IO::Capture::Stdout/;
sub grep {
my $self = shift;
for $line (
