Hallo, ich habe mir folgendes Script runtergeladen (es soll Barcodes erzeugen)
Problem: Auf meinem Webserver gehts, lokal (Hab dieses Xampp PAket installiert) gehts nicht. Er kann die Grafik nicht darstellen, kommt immer nur ein rotes Kreuz. Kann es daran liegen, das ic hirgendso eine Grafikbibiliotek nicht habe? Wo bekomme ich die, und wie installiere ich die? Danke!
PHP-Code:
<?php
$text = implode($argv, " ");
$barcodeheight=40;
$barcodethinwidth=2;
$barcodethickwidth=$barcodethinwidth*3;
$codingmap = Array( "0"=> "000110100", "1"=> "100100001",
"2"=> "001100001", "3"=> "101100000", "4"=> "000110001",
