PHP 8 error

[IXBONE IXBONE]

Fatal error: Uncaught Error: Undefined constant "IMG_PNG" in C:\PHP\jpgraph\src\jpgraph_errhandler.inc.php:282 Stack trace: #0 C:\PHP\jpgraph\src\jpgraph_errhandler.inc.php(156): JpGraphErrObjectImg->Raise('This PHP instal...') #1 C:\PHP\jpgraph\src\jpgraph_errhandler.inc.php(161): JpGraphException->Stroke() #2 [internal function]: JpGraphException::defaultHandler(Object(JpGraphExceptionL)) #3 {main} thrown in C:\PHP\jpgraph\src\jpgraph_errhandler.inc.php on line 282

Any suggestions? Thanks!

In jpgraph.php near line 162 you may try adding the code shown below. None of the image types were defined so using another image type would throw an error too. Not 100% sure this will solve the issue but it should.

define('IMG_JPG',false);
define('IMG_GIF',false);
define('IMG_PNG',false);
define('IMG_WBMP',false);
define('IMG_XPM',false);
