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
