// Directories for cache and font directory. 
//
// CACHE_DIR:
// The full absolute name of the directory to be used to store the
// cached image files. This directory will not be used if the USE_CACHE
// define (further down) is false. If you enable the cache please note that
// this directory MUST be readable and writable for the process running PHP.
// Must end with '/'
//
// TTF_DIR:
// Directory where TTF fonts can be found. Must end with '/'
//
// The default values used if these defines are left commented out are:
//
// UNIX:
//   CACHE_DIR /tmp/jpgraph_cache/
//   TTF_DIR   /usr/X11R6/lib/X11/fonts/truetype/
//
// WINDOWS:
//   CACHE_DIR $SERVER_TEMP/jpgraph_cache/
//   TTF_DIR   $SERVER_SYSTEMROOT/fonts/
//

// DEFINE("CACHE_DIR","/tmp/jpgraph_cache/");
// DEFINE("TTF_DIR","/usr/X11R6/lib/X11/fonts/truetype/");


//-------------------------------------------------------------------------
// Cache directory specification for use with CSIM graphs that are
// using the cache.
// The directory must be the filesysystem name as seen by PHP
// and the 'http' version must be the same directory but as 
// seen by the HTTP server relative to the 'htdocs' ddirectory. 
// If a relative path is specified it is taken to be relative from where
// the image script is executed.
// Note: The default setting is to create a subdirectory in the 
// directory from where the image script is executed and store all files
// there. As ususal this directory must be writeable by the PHP process.
DEFINE("CSIMCACHE_DIR","csimcache/"); 
DEFINE("CSIMCACHE_HTTP_DIR","csimcache/");

//------------------------------------------------------------------------
// Defines for font setup
//------------------------------------------------------------------------

// Actual name of the TTF file used together with FF_CHINESE aka FF_BIG5
// This is the TTF file being used when the font family is specified as
// either FF_CHINESE or FF_BIG5
DEFINE('CHINESE_TTF_FONT','bkai00mp.ttf');

// Special unicode cyrillic language support
DEFINE("LANGUAGE_CYRILLIC",false);

// If you are setting this config to true the conversion
// will assume that the input text is windows 1251, if
// false it will assume koi8-r
DEFINE("CYRILLIC_FROM_WINDOWS",false);

//------------------------------------------------------------------------
// Various JpGraph Settings. Adjust accordingly to your
// preferences. Note that cache functionality is turned off by
// default (Enable by setting USE_CACHE to true)

// Deafult graphic format set to "auto" which will automatically
// choose the best available format in the order png,gif,jpeg
// (The supported format depends on what your PHP installation supports)
DEFINE("DEFAULT_GFORMAT","auto");

// Should the image be a truecolor image? 
// Note 1: Has only effect with GD 2.0.1 and above.
// Note 2: GD 2.0.1 + PHP 4.0.6 on Win32 crashes when trying to use 
// trucolor.
// Note 3: MUST be enabled to get background images working with GD2
DEFINE('USE_TRUECOLOR',true);

// Specify what version of the GD library is installed.
// If this is set to 'auto' the version will be automatically 
// determined.
// However since determining the library takes ~1ms you can also 
// manually specify the version if you know what version you have. 
// This means that you should 
// set this define to true if you have GD 2.x installed to save 1ms. 
DEFINE("USE_LIBRARY_GD2",'auto');

// Should the cache be used at all? By setting this to false no
// files will be generated in the cache directory.  
// The difference from READ_CACHE being that setting READ_CACHE to
// false will still create the image in the cache directory
// just not use it. By setting USE_CACHE=false no files will even
// be generated in the cache directory.
DEFINE("USE_CACHE",false);

// Should we try to find an image in the cache before generating it? 
// Set this define to false to bypass the reading of the cache and always
// regenerate the image. Note that even if reading the cache is 
// disabled the cached will still be updated with the newly generated
// image. Set also "USE_CACHE" below.
DEFINE("READ_CACHE",true);

// Determine if the error handler should be image based or purely
// text based. Image based makes it easier since the script will
// always return an image even in case of errors.
DEFINE("USE_IMAGE_ERROR_HANDLER",true);

// Determine if the library should also setup the default PHP
// error handler to generate a graphic error mesage. This is useful
// during development to be able to see the error message as an image
// instead as a "red-cross" in a page where an image is expected.
DEFINE("INSTALL_PHP_ERR_HANDLER",false);

// If the color palette is full should JpGraph try to allocate
// the closest match? If you plan on using background images or
// gradient fills it might be a good idea to enable this.
// If not you will otherwise get an error saying that the color palette is 
// exhausted. The drawback of using approximations is that the colors 
// might not be exactly what you specified. 
// Note1: This does only apply to paletted images, not truecolor 
// images since they don't have the limitations of maximum number
// of colors.
DEFINE("USE_APPROX_COLORS",true);

// Should usage of deprecated functions and parameters give a fatal error?
// (Useful to check if code is future proof.)
DEFINE("ERR_DEPRECATED",true);

// Should the time taken to generate each picture be branded to the lower
// left in corner in each generated image? Useful for performace measurements
// generating graphs
DEFINE("BRAND_TIMING",false);

DEFINE("BRAND_TIME_FORMAT","(%01.3fs)");

//------------------------------------------------------------------------
// The following constants should rarely have to be changed !
//------------------------------------------------------------------------

// What group should the cached file belong to
// (Set to "" will give the default group for the "PHP-user")
// Please note that the Apache user must be a member of the
// specified group since otherwise it is impossible for Apache
// to set the specified group.

// (Set to "" will give the default persmissions for the "PHP-user")
DEFINE("CACHE_FILE_MOD",0664);

// Decide if we should use the bresenham circle algorithm or the
// built in Arc(). Bresenham gives better visual apperance of circles 
// but is more CPU intensive and slower then the built in Arc() function
// in GD. Turned off by default for speed
DEFINE("USE_BRESENHAM",false);

// Special file name to indicate that we only want to calc
// the image map in the call to Graph::Stroke() used
// internally from the GetHTMLCSIM() method.
DEFINE("_CSIM_SPECIALFILE","_csim_special_");

// HTTP GET argument that is used with image map
// to indicate to the script to just generate the image
// and not the full CSIM HTML page.
DEFINE("_CSIM_DISPLAY","_jpg_csimd");

// Special filename for Graph::Stroke(). If this filename is given
// then the image will NOT be streamed to browser of file. Instead the
// Stroke call will return the handler for the created GD image.
