I responded to your post on GIMPtalk but thought I'd echo it here for
posterity's sake...
You will need to start the GIMP's Script-fu server plug-in and then
have your PHP program talk to the server over a TCP port. Script-fu
commands are sent over the TCP port prefixed by "Gxy" where x and y
together specify the length of the command in bigEndian-style.
Here is a quick run-through (for GNU/Linux using BASH):
1. As root, create a file /dev/tcp/127.0.0.1/10008
2. As root, chmod the mode of that file to 666
3. start the GIMP in the background with the server plug-in being
the only interface:
gimp -i -b '(plug-in-script-fu-server 1 10008
"/home/cuongvt/script-fu-server.log")' &
4. To monitor the activity, run
tail -f /home/cuongvt/script-fu-server.log (you will need
to wait a while for GIMP to start up)
5. From another shell, type the following:
echo -e "G\0000\0015(gimp-quit 0)" >/dev/tcp/127.0.0.1/10008
(The '\0000\0015' part is the string length of "(gimp-quit 0)" as
characters specified in octal.)
You should see messages similar to the following appear in the log file:
Server: connect from host 127.0.0.1, port XXXXX.
Received request #0 from IP address 127.0.0.1: (gimp-quit 0) on
Thu Dec 11 16:44:57 2008
,[Request queue length: 1]Processing request #0
Of course, you will want to use a PHP client (instead of "echo") and
to have it count the string lengths and provide the proper prefix
automatically. Also, I don't use PHP and don't know how it sends and
receives data over a TCP port.
