NAME

       Perlbal::Plugin::Palimg -  plugin that allows Perlbal to serve palette altered images

VERSION

       This documentation refers to "Perlbal::Plugin::Palimg" that ships with Perlbal 1.50

DESCRIPTION

       Palimg is a perlbal plugin that allows you to modify "GIF" and "PNG" on the fly.  Put the images you want to be able to modify into the
       "DOCROOT/palimg/" directory.  You modify them by adding "/pSPEC" to the end of the url, where SPEC is one of the below defined commands
       (gradient, tint, etc).

CONFIGURING PERLBAL

       To configure your Perlbal installation to use Palimg you'll need to "LOAD" the plugin then add a service parameter to a "web_server"
       service to activate it.

       Example "perlbal.conf":

	   LOAD palimg

	   CREATE SERVICE palex
	      SET listen	 = ${ip:eth0}:80
	      SET role		 = web_server
	      SET plugins	 = palimg
	      SET docroot	 = /usr/share/doc/
	      SET dirindexing	 = 0
	   ENABLE palex

GRADIENTS

       You can change the gradient of the image by adding "/pg0011111164ffffff" to the end of the url.	00 is the index where the gradient starts
       and 111111 is the color (in hex) of the beginning of the gradient.  64 is the index of the end of the gradient and "ffffff" is the color of
       the end of the gradient.  Note that all colors specified in hex should be lowercase.

       Example:

	       http://192.168.0.1/palimg/logo.gif/pg01aaaaaa99cccccc

TINTING

       You can tint the image by adding "/pt000000aaaaaa" to the end of the url.  000000 should be replaced with the color to tint towards.
       "aaaaaa" is optional and defines the "dark" tint color.	Both colors should be specified as lowercase hex numbers.

       Example:

	       http://192.168.0.1/palimg/logo.gif/pt1c1c1c22dba1

PALETTE REPLACEMENT

       You can specify a palette to replace the palette of the image.  Do this by adding up to six sets of seven hex lowercase numbers prefixed
       with "/p" to the end of the URL.

       Example:

	       http://192.168.0.1/palimg/logo.gif/p01234567890abcfffffffcccccccddddddd
