RE: [hobbit] PDF Reports

[<wiskbroom (at) hotmail.com>]

[root (at) xymon-1 pdf]# grep "\$graphload-woalpha.png" report.skel.php

        imagePNG($img, "$graphload-woalpha.png");
        $pdf->Image("$graphload-woalpha.png",10,40,190,60,$extn,'', true, 72) ;
        unlink("$graphload-woalpha.png");

Thus, I only found one line containing:

imagePNG($img, "$graphload-woalpha.png"); 

Changing this one line to:

imagePNG($img, "$graphload");

Resulted in the same missing graphs.
