[hobbit] PDF Reports

[Thomas Séglard]

I think something is broken - again - in the transparency conversion. I 
quote Johan Grotherus (thanks to him) who said something very useful 
about this. Could you try his workaround, please ?

I have checked the scripts and found the problem to be in the 
analysis.skel.php and report.skel.php files.

This is the original code from report.skel.php

//
// Place the cpu load graph and text here
//
       $pdf->SetXY(25,30);
       $pdf->Image($imageload,10,26,0,13) ;
       $pdf->Titre($titreload);
       if (file_exists($graphload)) {
               $img = ImageCreateFromPNG($graphload) ;
               imageAlphaBlending($img, false);
               imageSaveAlpha($img, false);
               imagePNG($img, "$graphload-woalpha.png");
               
$pdf->Image("$graphload-woalpha.png",10,40,190,60,$extn,'', true, 72) ;
               unlink("$graphload-woalpha.png");
       } else {
               $pdf->Cell(10,20,$nograph,0,1) ;
               $pdf->Ln(80);
       }

I simply used the sed command to change the imagePNG($img, 
"$graphload-woalpha.png"); to imagePNG($img, "$graphload"); to get it to 
work. I did that for every section.
