Hi There,

in our company, we use the quickpdflibrary to print text to existing pdfs on our Webserver via php.

Now I have to edit or to fix files that were created by other guys.

I´m absolutely new to the pdflibrary and need some help.

I used the search- function to figure out how to enable an errorlog or something else, but there was no matching result for me.

My problem:

# using a ttf-font, wich is in the same folder like the script - SPK Logos.ttf

# --------------------------------------------------------------------------------------

$slogo = $qp->AddTrueTypeFont("SPK Logos",1);

$qp->SelectFont($slogo);

$qp->SetTextColorCMYK(0,0,0,0);

$qp->SetTextSize(30*$faktor);

$qp->DrawText($posx-(4.8*$faktor), $posy-10, 'p');

The rendered Letter 'p' in my pdf-file used the default font and not the selected font SPK Logos.

The php-errorlog is empty an in the quickpdf programfolder is no logfile.

Any ideas?

thx marco

Hi Marco,

QuickPDF offers LastErrorCode:

http://www.debenu.com/docs/pdf_library_reference/LastErrorCode.php" rel="nofollow - http://www.debenu.com/docs/pdf_library_reference/LastErrorCode.php

You can use this function after important process-steps to see if it's still alright.

Another idea is to check the returning values from the functions.

For example the returning value 0 by LoadFromFile means that there's an error...

Cheers and welcome here,

Ingo

HI Ingo,

thanks for your idea. That was the first thing I tried. The return values were all id numbers. No 0 value and when I called LastErrorCode the whole script stopped.

In the meantime I fixed the problem by using the method AddOpenTypeFontFromFile instead of addTrueTypeFont . That is working, but I don´t understand why the old function isn´t working anymore.

regards,

Marco
