Requirements:
-------------
Miminum:
* PHP 4.3.5 or higher
(earlier versions might work but is unsupported)
* GD 1.8.x or GD 2.15 or higher
Recommended:
* PHP 4.4.0
* PHP Builtin GD 2.28 library
Installation
------------
0. Make sure that the PHP version is compatible with the stated requirements
and that the PHP installation has support for the GD library.
Please run phpinfo() to check if GD library
is supported in the installation.
If the GD library doesn't seem to be installed
please consult the PHP manual under section "Image" for
instructions on where to find this library. Please refer to
the manual section "Verifying your PHP installation"
1. Unzip and copy the files to a directory of your choice where Your
httpd sever can access them.
For a global site installation you should copy the files to
somewhere in the PHP search path.
2. Check that the default directory paths in jpg-config.inc
for cache directory and TTF directory suits your installation.
Note1: The default directories are different depending on if
the library is running on Windows or UNIX.
Note2: Apache/PHP must have write permission to your cache
directory if you enable the cache feature. By default the cache
is disabled.
3. Check that all rest of the DEFINE in jpg-config.inc
is setup to your preference. The default should be fine
for most users. (See also Note 3. below)
4. If any problems are encounted please start by reading the FAQ on
http://www.aditus.nu/jpgraph/jpgraphfaq.php.
Documentation
-------------
The installation includes HTML documentation and reference guide for the
library. The portal page for all the documentation is
<YOUR-INSTALLATION-DIRECTORY>/docs/index.html
Troubleshooting
---------------
0. Make sure your PHP installation has the minimum requirements and has
the GD library enabled (most modern installations fulfills the minimmum
requirements). See chapter 3.1 in the manual.
1. If an empty page is returned back when running an example check
the following
i) Increase the maximum memory allowed by PHP (in php.ini) to at least 32MB
ii) Enable all error messages and notices in php.ini (error_reporting = E_ALL)
III) Make sure output buffering is disabled in php.ini (output_buffering = Off)
this will make it possible to see the errors more easily
IV) Disable any PHP accelerometer you may have installed (e.g. Zend Cache)
Then try running the example again. Most likely an error message will
now be shown that will give further information on what is wrong.
For further clarifiction on the casues for the error messages see
the FAQ section on the WEB site.
2. If you are running IIS and Win2k and get the error "Can't find
font' when trying to use TTF fonts then try to change you paths
to UNIX style, i.e. "/usr/local/fonts/ttf/". Remember that the
path is absolute and not relative to the htdocs catalogue. Some
versions of GD for Windows also need you to set the environment
variable GDFONTPATH for GD to find the fonts.
3. If you are using the cache please make sure that you have
set the permissions correctly for the cache directory so that
Apache/PHP can write to that directory.
