Hello Paul,

can you help me with this issue. I have problem with parsing of pdf file below:
PHP Fatal error: Allowed memory size of ... bytes exhausted. Version of pdf file is 1.3.
https://drive.google.com/file/d/0BzI_iKD4AN2aSGpDeTVjZjI2dms/view?usp=sharing.

Thank you for your help.

Cannot read pdf 1.2 version. tcpdi_parser line:259 error in foreach.

Uninitialized string offset: 59 application/third_party/tcpdf/tcpdi_parser.php 828
The line on 828

$frag = $data{$offset} . @$data{$offset+1} . @$data{$offset+2} . @$data{$offset+3};

Should change to

$frag = isset($data{$offset}) ? $data{$offset} : '';
                $frag .= isset($data{$offset+1}) ? $data{$offset+1} : '';
                $frag .= isset($data{$offset+2}) ? $data{$offset+2} : '';
                $frag .= isset($data{$offset+3}) ? $data{$offset+3} : '';

Is it possible to make it composer autoload ready?

Dear Paul,

I can't merge the attached file because it stops with "Illegal string offset 'Type" at line 704 of the tcpdi_parser file.

protected function getRawObject($offset=0, $data=null) {
if ($data == null) {
$data =& $this->pdfdata;
}
$objtype = ''; // object type to be returned
$objval = ''; // object value to be returned
// skip initial white space chars: \x00 null (NUL), \x09 horizontal tab (HT), \x0A line feed (LF), \x0C form feed (FF), \x0D carriage return (CR), \x20 space (SP)
while (strspn($data{$offset}, "\x00\x09\x0a\x0c\x0d\x20") == 1) {
$offset++;
}

Can you help me in this problem?

Hello

I think I have a similar issue to #8 -

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 57065 bytes) in /var/www/html/rmtest/tcpdi_parser.php on line 852

I'm using raw data, but if you would like the pdf I can send it privately if required.

All the best

Ken

Hi,

I'm trying to write on a PDF file v.1.5, but it doesn't work. The original file has 7 pages, the new one has only one blank page except for a black line on the top. For privacy reason I can't attach the file.

I'm using a try - catch block to catch exceptions but I don't get any error...
Here is my code:
`
require('../../../lib/tcpdf/tcpdf.php');
require('../../../lib/tcpdf/tcpdi.php');
try{
$pdf = new TCPDI();
$pageCount = $pdf->setSourceData($content);

$pdf->SetDrawColor(255,0,0);
$pdf->SetTextColor(255,0,0);
$pdf->SetPrintFooter(false);

$pdf->SetFont('helvetica','',8);

for ($pageNo = 1; $pageNo <= $pageCount; $pageNo++) {
	$tplIdx = $pdf->importPage($pageNo);

	$size = $pdf->getTemplateSize($tplIdx);
	$w = $size[w];
	$h = $size[h];
					
	if ($h > $w ){ // Il PDF è Portrait 
		$pdf->AddPage("P");
	}else{	// Il PDF è Landscape
		$pdf->AddPage("L");
	}
					
	$pdf->useTemplate($tplIdx);							
	$pdf->SetXY(0.2,5,true);
	$larghezzaFoglio = $pdf->getPageWidth();
	$pdf->Cell($larghezzaFoglio-0.4, 5, "  ".$stringaTimbro, 1,1,'L');
}
$pdf->Output($name, "D");

} catch (Exception $e) {
echo($e);
}
`

I'm using FPDF_TPL - Version 1.2.3, TCPDF Version 6.2.12, TCPDF parser Version 1.0.16, TCPDI parser Version 1.1, TCPDI - Version 1.0.
Please let me know if you need more informations.

Hi,

I'm trying to use your tcpdi and tcpdi_parser for handling PDF files in PHP but I have some issue. I have old PDFs in 1.4 version, they're okay. But I have new PDFs in 1.5 version and there is some issue with them. I've got the following error message when I'm trying to import them with tcpdi:
TCPDF_PARSER ERROR: Unknown PNG predictor 1

Here is a code snipplet I used for importing:

My php script stops running after the $pagecount row.

Reported as pauln/tcpdi#7 - but actually related to this project.

I'm attempting to merge/combine TWO pdf files. They are encoded/text PDF files so I'm using "setSourceData". Also, I'm using a modified example file

code here:
http://paste.ofcode.org/vVb6tf83tcWj8mGBYRJxea

I'm getting this error:
TCPDI_PARSER ERROR [tcpdi-56a25ce24b2d6]: Unable to find startxref

I have problem when use tcpdi parser. Error happend when I parse this file.
W8 Ben-E.pdf

How can I solve this error.

Thank you so much!

I've got a special set of pdfs which cause this error in the following line:

It should be related to the warning here: http://php.net/manual/en/migration71.other-changes.php

According to XDebug it tries to do the following but fails:

$this->objstreamobjs["x��XmO#G��޿��/�Ec�K�[�EbḠܲ(���"] = [[3, 0], 218];

This trailer section will cause parsing to fail with an Unable to find trailer error:

trailer
<</Root 71 0 R/ID [<301161dc6cb4aa570159c409124baab9>]/Info 72 0 R/Size 73>>
%comments-here
startxref
143557
%%EOF

The regex pattern in line 408 can be changed to allow comment lines:
old:

'/trailer[\s]<<(.)>>[\s][\r\n]+startxref[\s][\r\n]+/isU'

new:

'/trailer[\s]<<(.)>>[\s][\r\n]+(?:[%].[\r\n])startxref[\s][\r\n]+/isU'

I'm not 100% certain that comments are allowed in the trailer section, but I've encountered some files that have them. These files appear to have been created by iText.

I've been using this library for a while and has been great so far. Today I got an error after a user tried to upload a PDF made using LaTeX.

A Screenshot of the error:

Here are the PDF properties:

Hope you guys can help.

I've been using this package for over a year now and suddenly started getting memory exhaustion errors
PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 20480 bytes) in <[...]>/tcpdi_parser.php on line 882
Here's my code

public function downloadFiles($files, $name = 'name.pdf'){
      $pdf = new \TCPDI();
      $pdf->SetPrintHeader(false);
      $pdf->SetPrintFooter(false);
      $filesArr = [];
      $pdf->SetTitle($name);
      foreach($files as $f){
        $filePath = $f->getFirstMedia('pdf')->getFullUrl();
        $width = $f->sheetsize->width;
        $height = $f->sheetsize->height;
        $port_land = ($width > $height) ? "landscape" : "portrait";
        $pdf->AddPage($port_land, array($width, $height));

  	$pageCount = $pdf->setSourceFile($filePath);
        for($i = 1; $i <= $pageCount; $i+=1)
        {
          $tplId = $pdf->importPage($i);
          $pdf->useTemplate($tplId, 0, 0, $width);
          if($pageCount > $i){
            $pdf->AddPage();
          }
        }

      }
      $name = str_replace('.pdf', '', $name).'.pdf';
      $pdf->Output($name, "I");
    }

I'm attaching one of the pdfs that causes this error, I'm really lost at where should I even begin to look for the problem.
problems.pdf

I've not read anything that's led me to believe that TCPDI shouldn't work with v1.3 PDFs but each time we try to setSourceFile to a PDF generated by DOMPDF I get "TCPDF_PARSER ERROR: Invalid object reference: Array". The PDFs will open in Acrobat Reader without complaint.

Example PDF here:
http://test.semlyen.net/problematic-PDF.pdf
(not from a real rent agreement!)

Any ideas?

I couldn't find any mention of this in the code, but does this currently support the ability to parse form fields and get their x,y positions or even better allow the ability fill them in?

Since switching to PHP 7.2.4, we discovered this problem with our PDF merging tool, that makes use of this library.

The line in tcpdi_parser.php is this one:

    } elseif (($key == '/Index') AND ($v[0] == PDF_TYPE_ARRAY AND count($v[1] >= 2))) {

count($v[1] >= 2) is the cause of error here.

PHP 7.2 Backward incompatible changes:

http://php.net/manual/en/migration72.incompatible.php

The count() functions need to be replaced, or the objects used in them need to be Countable.

I don't have a solution to drop here yet. Any ideas, why the count is there?

If I just copy paste this instead of the parcer in mpdf , would it work?

I get this error
Uninitialized string offset: 35 application/third_party/tcpdf/tcpdi_parser.php 725

The line on 725 is in method getRawObject

while (strspn($data[$offset], "\x00\x09\x0a\x0c\x0d\x20") == 1) {
    $offset++;
}

Some idea how to change it? I don't understand what getRawObject should return in this cases.

Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, true given in ../tcpdi_parser.php:503

I've been trying to import PDF files using the following code:

$pdf = new TCPDI(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

// Import template
$pdf->AddPage ();
$pdf->setSourceFile ($path);
$idx = $pdf->importPage (1);
$pdf->useTemplate ($idx);

echo $pdf->Output ();

I had no problems with 1.5 and 1.7 PDF versions, but when I try it with 1.3 or 1.4 versions, the loop in getIndirectObject() never ends.

An example of a PDF not working: https://www.dropbox.com/s/9ax2lc5fed4erit/1.pdf

I've been trying to understand what is wrong, but I don't know enough about PDF formats.

Thanks

the parser crashes because it is not able to parse correctly this kind of PDF objects:

I have fixed it (only to avoid the crash) changing the **protected function getRawObject() from line 851 adding a check for an hypotetical fixed string object.

default: if (preg_match('/^([0-9]+)[\s]+([0-9]+)[\s]+([Robj]{1,3})/i', substr($data, $offset, 33), $matches) == 1) { if ($matches[3] == 'R') { // indirect object reference $objtype = PDF_TYPE_OBJREF; $offset += strlen($matches[0]); $objval = array(intval($matches[1]), intval($matches[2])); } elseif ($matches[3] == 'obj') { // object start $objtype = PDF_TYPE_OBJECT; $objval = intval($matches[1]).'_'.intval($matches[2]); $offset += strlen ($matches[0]); } } elseif (($numlen = strspn($data, '0123456789ABCDEF', $offset)) > 0) { // fixed string object if ($numlen == 6) { $objval = substr($data, $offset, $numlen); $objtype = PDF_TYPE_STRING; $offset += 6; } elseif (($numlen = strspn($data, '+-.0123456789', $offset)) > 0) { // numeric object $objval = substr($data, $offset, $numlen); $objtype = (intval($objval) != $objval) ? PDF_TYPE_REAL : PDF_TYPE_NUMERIC; $offset += $numlen; } } elseif (($numlen = strspn($data, '+-.0123456789', $offset)) > 0) { // numeric object $objval = substr($data, $offset, $numlen); $objtype = (intval($objval) != $objval) ? PDF_TYPE_REAL : PDF_TYPE_NUMERIC; $offset += $numlen; } unset($matches); break;

If a pdf has such an object like the followings, tcpdf_parser fails to continue parsing the data.

2 0 obj
<< /Type /Page % 1
   /Parent 1 0 R
   /MediaBox [ 0 0 839.314286 1186.971429 ]
   /Contents 4 0 R
   /Group <<
      /Type /Group
      /S /Transparency
      /I true
      /CS /DeviceRGB
   >>
   /Resources 3 0 R
>>

getRawObject() is expected to return an array which contains an object and its offset, but it currently returns an object without its offset if the pdf has % comments. It causes Illegal string offset warnings.

I've created a compact example. Would you please check it?

Hello,
I am trying to add watermarks to a an existing PDF by using this library:

$pdf = new TCPDI(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);  
if (file_exists(WatermarkPDF::$tmp_file)){  
    $pagecount = $pdf->setSourceFile($tmp_file);  
} else {  
    clear();  
    return FALSE;  
}

Unfortuantely I am getting an error:

Notice (8): Array to string conversion [APP/Vendor/WatermarkPDF/tcpdi_parser.php, line 951]  
TCPDI_PARSER ERROR: Invalid object reference: Array

The file is a valid PDF (v1.5) created by Latex so I am wondering whats wrong here..
