Intro and Info

Signature/Avatar Generator AddOn for Roster

Download ->
Support ->

Current version:
Documentation is for 0.3.0 and higher Updated: 01:26, 18 November 2008 (CST)
Author: Zanix

This is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY. So if it blows up your server it's not my fault
These signatures/avatars can be used for web forums, they will show a character's level, membership, rank, trade skill levels, and other such information.

The information in these signature graphics will be as up to date as the information in roster.
This is very configurable, everything can be moved fairly easily, text colors can be changed, almost everything can be displayed/hidden

To configure, open /roster/index.php?rostercp-addon-siggen (SEO: roster/rostercp/addon/siggen.html) in a web-browser

For members that haven't uploaded info, this will show limited information on a default background

To everyone else that I haven't mentioned
And all those that have tested the previous versions; sig1.5 : sig2.0 : sig2.0-gamma : etc...

Requirements Roster v2.0.0 or higher
PHP 4.3.2 or better
GD2 with PNG and Freetype Support

Advanced functions in SigGen Config may not work if safe_mode is turned on in your PHP config file
SigGen absolutely requires that your PHP installation supports the GD2 library, and that GD2 has PNG Support and FreeType Support turned on
RosterDiag MUST SAY FreeType Support: yes for you to use SigGen

FreeType Linkage: with freetype is best although with TTF may work ok

If you have trouble with the signature generator, first check RosterDiag for information about how the GD2 library is configured (or not available) on your web server

If you DO NOT want SigGen, or if you cannot get GD2 to work on your server, you can un-install SigGen via RosterCP -> Addon Management, then delete the folder from the addons directory /addons/siggen/ and that will remove all traces of SigGen

After installing SigGen, you will find a SigGen button on the character panel that will preview the signature and avatar images for that character as well as provide dynamic link URLs for each.

So if your roster URL is

Dynamic links:

SEO - Friendly Links Mode:

To get the graphic for a character named "Bob", use:

Now suppose you host multiple guilds or characters across multiple realms and there are characters with the same name.
You need to therefore be able to specify the realm in the URL to get the character of choice as follows:

If you host multiple guilds on multiple realms in multiple regions and have characters/guilds/realms that have the same name.
Then you need to specify the region as well:

For example:
To get the graphic for a character named "Bob" on the US realm called "MyRealm", use:

Alternatively, you can link directly to the generated image if you have chosen to save them on the server. The default file format is .png however this can be changed to .jpg or .gif.


For another method, you can use mod_rewrite to re-write the path to the generator files

Allows you to use

Replace MODE with the config setting (IE. signature | avatar) Replace Name@US-Realm with the character's name region and realm Replace EXT with the extension (IE. png | gif | jpg)

To use the this method, you must have an Apache server with mod_rewrite turned on
Or IIS users need an ISAPI filter

This only allows for the signature and avatar SigGen config designs
If you added other designs, you have to add them in the mod rewrite file

RewriteRule ^/?(signature|avatar|anotherconfig|more|purple)/(.*)

Apache and htaccess

Edit WoWRoster's .htaccess file


	RewriteEngine On


	RewriteRule ^/?(signature|avatar)/(.*)\.(.*)$ /index.php?p=util-siggen-$1&member=$2&format=$3

So the entire file looks like this

# WoWRoster .htaccess file
# $Id: .htaccess 1254 2007-08-19 16:41:28Z Zanix $

<IfModule mod_rewrite.c>
	RewriteEngine On
	RewriteRule ^/?(signature|avatar)/(.*)\.(.*)$ /index.php?p=util-siggen-$1&member=$2&format=$3

	RewriteCond %{REQUEST_FILENAME} -f [OR]
	RewriteCond %{REQUEST_FILENAME} -d

	RewriteRule ^(.+) - [PT,L]
	RewriteRule ^(.*) index.php

IIS and url-rewrite ISAPI filter

There is a way to mimic mod_rewrite on IIS using an ISAPI filter

One of these may work
You may need admin access to your IIS installation
I have not tested this, but I hear it does work

The original ISAPI filter I found some time ago has disappeared from the internet, so I have no clue how to configure these products


Now that you are sure that GD2 works properly on your server, here is how to get SigGen working

Before you even start trying to access the signatures/avatars, you need to run the configuration page in RosterCP

Log into SigGen Config

First you will need to get to SigGen config

Go to RosterCP, then click SigGen from the Addon Config menu
Or go to /roster/index.php?rostercp-addon-siggen (SEO: roster/rostercp/addon/siggen.html)

Install / Upgrade / Un-Install

Use RosterCP->Addon Management to install, upgrade, or un-install SigGen

SigGen Settings

Important Note
Alot of the settings on the SigConfig page have tooltips breifly describing what each function does
It's a VERY good idea to click Save Settings after you are done on each page, but it is not required
Note: Some settings will automatically "click" the Save Settings button

Advanced SigGen Options

The fine art of text placement

There are many options for adjusting the placement of the text within the image Here is a guide on how SigGen calculates where to draw the text

Alignment Horiz point Width of text Starts drawing Ends drawing
Left 200 50 200 250
0 30 0 30
395 10 395 405
Center 200 50 175 225
0 30 -15 15
350 10 345 355
Right 200 50 150 200
0 30 -30 0
350 10 340 350

Import / Export Settings

You can export and import your SigGen settings for backup or sharing with others


When exporting, SigGen will only export that config mode
So if you are in Signature config mode, hitting Export will save the config settings for Signatures
The file saved will be siggen_signature.txt


When importing, SigGen will only accept text files name like this


Where configname is the name of the config mode you are currently in

SigGen will also deny importing of newer DB version setting files
So if you saved from SigGen 0.2.5 (which is DB version 1.3) you cannot upload a saved config from this version to 0.2.0, which is DB version 1.2

Starting with SigGen 0.3.0, SigGen will accept a settings file with an older DB version

Image Packs

Image packs have a limited "themeing" ability in that you can specify code to handle how images are selected

Image packs are structured like so

  • img/
    • background/
      • pack1/
        • (image files)
      • pack2/
        • (image files)
    • character/
      • pack1/
        • (image files)
      • pack2/
        • (image files)
    • class/
      • pack1/
        • (image files)
      • pack2/
        • (image files)
    • pvp/
      • pack1/
        • (image files)
      • pack2/
        • (image files)
    • frame
      • (image files)
    • level
      • (image files)

Background image packs do not have a config file, there is no need for one since the Web config is already there

Class and PvP image packs have a file called
In this file, you specify the image extension tha will be used, either .png, .gif, or .jpg/.jpeg

Character image packs have a file called
Now this is where is gets interesting
(Some future version of SigGen will have a web config for this part, but not right now)

The file allows you to make an if statement to tell siggen.php how to pick a character image

If you do not include this file with a pack, then the default code will pick an image like this if character has race and gender, get race-gender.png

$char_ext = '.png';
if( !empty($sig_race) )
	// Set race-gender based image
	if( !empty($sig_gender) )
		// Set race-gender based image
		$im_user_file = $configData['image_dir'].$configData['char_dir'].$sig_race.'-'.$sig_gender.$char_ext;
	// Set race only image
		$im_user_file = $configData['image_dir'].$configData['char_dir'].$sig_race.$char_ext;
}	// Set default character image
	$im_user_file = $configData['image_dir'].$configData['char_dir'].$configData['charlogo_default_image'];

Image packs like the teir3 pack pick an image based on race-gender-class.png

if ( !defined('ROSTER_INSTALLED') )
    exit('Detected invalid access to this file!');
$char_ext = '.png';
if( !empty($sig_race) )
	// Set race-gender based image
	if( !empty($sig_gender) )
		// Set race-gender-class based image
		if( !empty($sig_class) )
			$im_user_file = $configData['image_dir'] . $configData['char_dir'] . $sig_race . '-' . $sig_gender . '-'
					. strtolower(getEnglishValue($sig_class,$sig_char_locale)) . $char_ext;
			$im_user_file = $configData['image_dir'] . $configData['char_dir'] . $sig_race . '-' . $sig_gender . $char_ext;
	// Set race only image
		$im_user_file = $configData['image_dir'].$configData['char_dir'].$sig_race.$char_ext;
}	// Set default character image
	$im_user_file = $configData['image_dir'].$configData['char_dir'].$configData['charlogo_default_image'];

siggen.php Direct Access and URL Switches

These are the URL arguments SigGen will accept

Custom Member Images

File:Addon siggen member-up-del.png
Custom Member Image Control


You can set custom images for each character for SigGen, and you can set a custom background as well

Getting images of characters
  1. Take a screenshot of your character in WoW
    Or even better, use WoW Model Viewer -
  2. Open your screenshot in your favorite image editor
  3. Edit out the background (make it transparent) and resize to fit inside the signature
    (With SigGen default settings, a good size is h-120px w-120px)
  4. Save it as .png, .gif, or .jpg format (24-bit .png with alpha transparency is best and recommended)
Uploading to SigGen Config

The images you upload can be in .png, .gif, or .jpg format (24-bit .png with alpha transparency is best and recommended)

Delete Member Images

This box will let you delete any currently uploaded images

Save Image Mode

File:Addon siggen savemode.png
SigGen Save Image Mode

This is how "Save Image Mode" works

When activated, every visit to SigGen when a name is specified, will generate the image and save it to the server as a static image

This mode is generally used in conjunction with the "Addon Update Trigger"

Auto-Save on Guild Update

Character Update

Auto-Save images for signatures and avatars

Combining the powers of "Save Image Mode" and "Addon Update Triggers", images can be automaticaly generated and saved on the server everytime update.php is ran

Turning these on will generate and save an image to the server's disk when a player updates their data
Only turn these on after you have configured the signatures

The "Saved Images Directory" has to exist for this to work

To activate, turn on "Auto-save image on character update" on the Main Settings page

Guild Update

This "auto-save mode" can also run during a guild update, which generates an image for every guild memeber

To activate, turn on "Auto-save images on guild update" on the Main Settings page

Important Note
You must also enable "Addon Update Triggers" in RosterCP->Configure Main Roster to activate this mode

WARNING: This can take a very long time.
Expect to wait up to 10 minutes, maybe even longer for larger amounts of characters when this is activated

An image is generated and placed on the update page for every member in the guild
Please wait for the page to fully finish downloading all the images to have all of them saved correctly
