Requirements:
-------------
Miminum:
* PHP 4.3 or higher
(earlier versions might work but is not actively tested)
* GD 1.8.x or GD 2.15 or higher
Recommended:
* PHP 4.3.7
* Builtin GD library in PHP 4.3.x
Installation
------------
0. Make sure your PHP is 4.3 (preferable 4.3.7)
and that you have compiled support for GD library.
You must make absolutely sure that you have GD working.
Please run phpinfo() to check if GD library
is supported in your installation. If you don't have the GD library
please consult the PHP manual under section "Image" for
instructions on where to find this library.
1. Unzip and copy the files to a directory of your choice. For
a global 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. Make sure PHP have write privileges to your cache directory if
you plan on using the cache feature.
5. Read (really!) the FAQ on http://www.aditus.nu/jpgraph/jpg_faq.php.
Troubleshooting
---------------
1. If you don't get any background images (but rather a solid black
box) you are using GD 2.x but have forgotten to enable truecolor
support. Correct this by enabling the USE_TRUECOLOR define.
2. If background images does not work make sure the settings of
USE_GD2_LIBRARY corresponds to your installation, i.e. If you
don't have GD2 then this define must be false!
3. 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.
4. 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.
5. Some windows installations seems to have a problem with a PHP
script ending in a newline (This newline seems to be sent to the
browser and will cause a Header already sent error).
If you have this problem try remove all trailing newlines in the
jpgraph* files
