Run testsuit.php to get a list of all files and you can easily click on a file to see the code and the resulting image. /docs Directory with all documentation /docs/index.html Documentation portal Requirements: ------------- Miminum: * PHP 5.1.0 or higher * GD 2.28 or higher Note: Earlier versions might work but is unsupported. Recommended: * PHP 5.1.2 * PHP Builtin GD 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. Read (really!) the FAQ on http://www.aditus.nu/jpgraph/jpg_faq.php. Documentation ------------- The installation includes HTML documentation and reference guide for the library. The portal page for all the documentation is /docs/index.html Troubleshooting --------------- 1. If an empty page is returned back when running an example check the following i) Make sure output_buffer is disabled in php.ini ii) Increase the maximum memory allowed by PHP (in php.ini) to at least 32MB iii) Enable all error messages and notices in php.ini (error_reporting = E_ALL) 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. 1. 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. 2. 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. 3. 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
