12

DESCRIPTION

14       Palimg is a perlbal plugin that allows you to modify "GIF" and "PNG" on
15       the fly.  Put the images you want to be able to modify into the
16       "DOCROOT/palimg/" directory.  You modify them by adding "/pSPEC" to the
17       end of the url, where SPEC is one of the below defined commands
18       (gradient, tint, etc).
19

CONFIGURING PERLBAL

21       To configure your Perlbal installation to use Palimg you'll need to
22       "LOAD" the plugin then add a service parameter to a "web_server"
23       service to activate it.
24
25       Example "perlbal.conf":
26
27           LOAD palimg
28
29           CREATE SERVICE palex
30              SET listen         = ${ip:eth0}:80
31              SET role           = web_server
32              SET plugins        = palimg
33              SET docroot        = /usr/share/doc/
34              SET dirindexing    = 0
35           ENABLE palex
36

GRADIENTS

38       You can change the gradient of the image by adding
39       "/pg0011111164ffffff" to the end of the url.  00 is the index where the
40       gradient starts and 111111 is the color (in hex) of the beginning of
41       the gradient.  64 is the index of the end of the gradient and "ffffff"
42       is the color of the end of the gradient.  Note that all colors
43       specified in hex should be lowercase.
44
45       Example:
46
47               http://192.168.0.1/palimg/logo.gif/pg01aaaaaa99cccccc
48

TINTING

50       You can tint the image by adding "/pt000000aaaaaa" to the end of the
51       url.  000000 should be replaced with the color to tint towards.
52       "aaaaaa" is optional and defines the "dark" tint color.  Both colors
53       should be specified as lowercase hex numbers.
54
55       Example:
56
57               http://192.168.0.1/palimg/logo.gif/pt1c1c1c22dba1
58

PALETTE REPLACEMENT

60       You can specify a palette to replace the palette of the image.  Do this
61       by adding up to six sets of seven hex lowercase numbers prefixed with
62       "/p" to the end of the URL.
63
64       Example:
65
66               http://192.168.0.1/palimg/logo.gif/p01234567890abcfffffffcccccccddddddd
