NAME

Gimp::Net - Communication module for the gimp-perl server.

SYNOPSIS

use Gimp;

DESCRIPTION

For Gimp::Net (and thus commandline and remote scripts) to work, you first have to install the "Perl-Server" extension somewhere where Gimp can find it (e.g in your .gimp/plug-ins/ directory). Usually this is done automatically while installing the Gimp extension. If you have a menu entry <Xtns/Perl-Server> then it is probably installed.

The Perl-Server can either be started from the <Xtns> menu in Gimp, or automatically when a perl script can't find a running Perl-Server.

When started from within The Gimp, the Perl-Server will create a unix domain socket to which local clients can connect. If an authorization password is given to the Perl-Server (by defining the environment variable GIMP_HOST before starting The Gimp), it will also listen on a tcp port (default 10009). Since the password is transmitted in cleartext, using the Perl-Server over tcp effectively lowers the security of your network to the level of telnet.

ENVIRONMENT

The environment variable GIMP_HOST specifies the default server to contact and/or the password to use. The syntax is [auth@][tcp/]hostname[:port] for tcp, [auth@]unix/local/socket/path for unix and spawn/ for a private gimp instance. Examples are:

www.yahoo.com               # just kidding ;)
yahoo.com:11100             # non-standard port
tcp/yahoo.com               # make sure it uses tcp
authorize@tcp/yahoo.com:123 # full-fledged specification

unix/tmp/unx                # use unix domain socket
password@unix/tmp/test      # additionally use a password

authorize@                  # specify authorization only

spawn/                      # use a private gimp instance

CALLBACKS

net()

is called after we have succesfully connected to the server. Do your dirty work in this function, or see Gimp::Fu for a better solution.

FUNCTIONS

server_quit()

sends the perl server a quit command.

get_connection()

return a connection id which uniquely identifies the current connection.

set_connection(conn_id)

set the connection to use on subsequent commands. conn_id is the connection id as returned by get_connection().

BUGS

(Ver 0.04) This module is much faster than it ought to be... Silly that I wondered wether I should implement it in perl or C, since perl is soo fast.
