PDF Reports

[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.

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.

1) could you please, try an older version of TCPDF ? I suspect an
incompatibility between your RRDTOOL version and TCPDF.

I haven't done this yet, but I will try after sending you the data below, but I am only able to see the two most recent at http://sourceforge.net/projects/tcpdf/files/

2) could you give me the output for this command :
shell$ file pdf/graphrrd/CLIENT/load.CLIENT-year.png

[root at xymon-1 graphrrd]# file ./CLIENT/load.CLIENT-2week.png
./CLIENT/load.CLIENT-2week.png: PNG image data, 697 x 193, 8-bit/color RGBA, non-interlaced

For your information, here is mine :
graphrrd/www01/cputil.www01-2day.png: PNG image data, 697 x 255,
8-bit/color RGBA, non-interlaced

Looks quite similiar.

Then, green circle you saw on second page, is generated with the values
on the left. These values are calculated by the "master.sh" script. You
should see in your "graphrrd" directory csv files. You can open csv to
look at the values. If you have none, maybe something has changed in
Xymon 4.3.x ? I'm using the following command to generate csv :

Not sure about this, BUT if I point my browser at:

http://xymon-1.example.com/pdf/graphrrd/CLIENT/load.CLIENT-2week.png

It displays a beautiful graph generated using RRD. I am not sure why it is not displaying properly within the tcpdf report, perhaps a misconfiguration somewhere? (I've searched hard..)
