I'd like to add an item on the last page of an existing PDF. The Item is added by an commercial non modifiable API.
The positon and size is definied relative to the Page. To support diffrent page formats, I have to get the page size of the existing PDF.
I've tried it with FPDI/FPDF but there are warnings. I'm not allowed to update the version.
Next try with the TCPDF doesn't throw an exception but after the import the function getNumPages returns 0;
Is there a possibility to get the page size of a PDF without using a library or a command line tool?
I have solved the problem by fixing the existing fpdi library. There were only small problems with the compatibility with newer PHP Versions. I've solved them. So I could use the following snippet:
$oPDF = new fpdi();
$iPageCount = $oPDF->setSourceFile($sFileLocation);
$mTemplateId = $oPDF->importPage($iPageCount);
$aTemplateSize = $oPDF->getTemplateSize($mTemplateId);

We have a project where we merge different pdfs to create a catalog.
Right now it's running on myokyawhtun/pdfmerger, which runs fine, but it does not keep links set in acrobat.
We have tried different libraries we found (pure PHP, we cannot install or call applications from the command line via shell-exec or similar on this webspace, so no gs), even if we just import the pdf-files via fpdi and resave them, the hyperlinks get lost.
Is there any (pure PHP) library out there which can retain links inside the files? Or are there some special settings that we missed?
We have tried:
setasign/fpdi
iio/libmergepdf
jurosh/pdf-merge
Example code for the current lib (myokyawhtun/pdfmerger):
require('vendor/myokyawhtun/pdfmerger/tcpdf/tcpdf.php');
require('vendor/myokyawhtun/pdfmerger/tcpdf/tcpdi.php');
require('vendor/myokyawhtun/pdfmerger/PDFMerger.php');
$pdf = new \PDFMerger\PDFMerger;
foreach($sourcePdfs as $file)
{
$pdf->addPDF($pdfDir.'/source/'.$file);
}
$pdf->merge('download', 'Download.pdf');
All the mentioned libraries use FPDI under the hood, which simply does not support content outside of a pages content stream, such as links or any other annotation type.
We (author of FPDI) also offer non-free products which work on another level and which allow you keep all annotations including links and also forms when you concatenate the documents. This is possible with the SetaPDF-Merger component:
$merger = new SetaPDF_Merger();
foreach($sourcePdfs as $file) {
$merger->addFile($pdfDir . '/source/' . $file);
}
$merger->merge();
$document = $merger->getDocument();
$document->setWriter(new SetaPDF_Core_Writer_Http('Download.pdf'));
$document->save()->finish();
I've run into this weird issue with PDF file handling. Not sure if SO is the right place to ask this, but I couldn't find any specific sites for this. I hope that someone can shed some light on the issue.
This happens with the following specific process, if some of steps are omitted - the issue is not observed.
I have a PHP application that serves PDF files to users. These files are created by authors in MS Word 2007, then printed to protected PDF (using pdf995, most likely, I can confirm if needed).
I'll call this initial PDF file as 'source' hereinafter.
Upon request, the source file is processed in PHP the following way:
we decrypt it using qpdf:
qpdf --decrypt "source.pdf" "tmp_output.pdf"
Then we add security label / wartermark to it, encrypt and output to browser using mPDF 6.0:
$mpdf = new mPDF();
$mpdf->SetImportUse();
$pagecount = $mpdf->SetSourceFile($fpath);
if ($pagecount) {
for ($i=1;$i<=$pagecount;$i++){
$tplId = $mpdf->ImportPage($i);
$mpdf->UseTemplate($tplId);
$html = '[security label / watermark contents...]';
$mpdf->WriteHTML($html);
}
}
$mpdf->SetProtection(array('copy','print'), '', 'password',128);
$mpdf->Output('final_output.pdf','I');
With the exact steps described above, images in the output that were pasted in the Word doc appear as follows:
In the source PDF, tmp_output (qpdf decrypted file) the pasted images look correct:
The distortion doesn't take place if any of the following occurs:
Word doc printed to PDF without protection
mPDF output is not protected.
As you can see there too many factors, so I don't know where to look for a bug.
Each component works correctly on it's own and I cannot find any info on the issue. Any insights are greatly appreciated.
EDIT 1
After some more testing, it appears that this only happens to screenshots taken from web browser, Windows explorer, MS Word. Cannot reproduce this with screenshots from Gimp.
It appears that something along the way attempts to convert white to alpha and fails.
The current version (6.1) of Mpdf has a bug which does not handle escaped PDF strings (imported via FPDI) correct if they should be encrypted.
A pull request, which fixes this issue is available here.
I want to generate a PDF that will contain an image.
so i already tried this line of codes:
$pdf->Image('b.png',10,8,33);
the other is:
$pdf->Image('Project_ITCPH\images.jpg', 1, 10, 5.8, 1.5);
the problem here is this Error:
"Deprecated: Function set_magic_quotes_runtime() is deprecated in C:\xampp\htdocs\Project_ITCPH\reports\fpdf.php on line 931
FPDF error: Alpha channel not supported: b.png"
is there a problem with the fpdf.php? i only use it as include.
You have my regards.
This error simply means that FPDF is using a function call that is deprecated and outdated. This is shown because your PHP displays errors and warnings and deprecation notes. You should try turning off errors before generating the PDF or writing # before function calls (like here) when using FPDF.
By the way, I highly recommend you use mPDF for PDF generation with PDF, it's better supported in my opinion.
Upgrade your FPDF to 1.7. It now supports alpha channel in PNGs.
Check out this class it lets you add images to PDF's with PHP it has a lot of demo's
https://github.com/dompdf/dompdf
Try
$pdf->Image('..\Project_ITCPH\images.jpg', 1, 10, 5.8, 1.5);
this is some time happen cause server could not find the folder path hope this work for u
also try this
require('fpdf.php');

According to the FPDF documentation here: http://www.fpdf.org/en/doc/image.htm
You are supposed to be able to use an Image from a dynamic source.. however, as per the first link, i'm getting an fopen error.
Any suggestions?
Code Snippet:
// Overlay Text & Images
$pdf->Image($conf['rbase'].'page_maker/image_hr.php?id=5&side=1&bg=cover_pink&lo=0_1&imgtxt=0|0|u5_1310329746.jpg##1|1|Elina\'s Puppies 9/2/2010|15|arial_bi.ttf|db0ddb|fedfe4&applet_type=cover',$sx,$sh,(0-$dpi), 0, 'png');
You are trying to open a local php file with get parameters - try instead to open the image file as a url. For example :
http://domain.com/image.php?id=5
Or in your case...
http://babymoments.co/preview/page_maker/image_hr.php?id=5&side=1&bg=cover_pink&lo=0_1&imgtxt=0|0|u5_1310329746.jpg##1|1|Elina's%20Puppies%209/2/2010|15|arial_bi.ttf|db0ddb|fedfe4&applet_type=cover
I wouldn't fetch the preview over HTTP but would include the required code and generate the image in the same script that generates the PDF. That way there is no problems with setups that have disabled fopen()-usage with URLs.
I was implementing a barcode for a label printer. So I was using the 'barcodegen' library and 'fpdf' library for this project, but I was having problems including dynamically the image generated with barcodegen, giving me the following error:
FPDF error: Not a PNG file: ./misc/barcodegen/mostrar-codigo-bcgcode39.php
Afeter that, I use one of the answers described here, and I solved the problem using the full URL of the image, like this:
$pdf->Image("http://localhost/caaf/misc/barcodegen/mostrar-codigo-bcgcode39.php",0,0,20,0,'PNG');
And it worked for me.
I'm trying to merge 2 PDF, one on my server (not dynamically generated) and one generated just before the merge and not saved anywhere on the server (I just want my client to download it). So I only have the pdf's content. Both PDF have the same format (A4).
The merged file will have 2 pages and won't be saved on server as well.
Since, I'm using Zend Framework, I would prefer a solution with it (can't find one online...) else any advice ?
(common solution found online but doesn't work)
Edit : because people are lazy to click. The code is in the link anyway since it's wrong and doesn't work.
I try the script below, but I get the
error:
Uncaught exception
'Zend_Pdf_Exception' with message
'Page is attached to one documen, but
rendered in context of another
Alright, with the guide from #Gordon 's comment in my question, I got a solution.
You must have at least Zend Framework 1.11 (I was in 1.9, first error) (found thanks to the 3rd comment to this question)
You must clone page from the PDF you want to merge, else, your application will print an error (self explanatory one) (found thanks to this slideshare which is very interesting for Zend_Pdf)
The static PDF must be a PDF <= 1.4 (mine was 1.6). Zend_Pdf can't parse PDF which version is > 1.4
I used this application to convert the static files I had in version 1.6 to 1.4.
Here's the rough code I have and work (I know it's not optimised, I'll do it later; but still, it can be useful)
$pdf2show = new Zend_Pdf(); // Initializing the merged PDF
$pdf1 = Zend_Pdf::parse($pdfContent, 1); // $pdfContent is the generated one, got the content...
$template = clone $pdf1->pages[0]; // cloning the page (a must do)
$page1 = new Zend_Pdf_Page($template); // Creating the first page of the merged PDF with the previous content
$pdf2show->pages[] = $page1; // Adding this page to the final PDF
$pdf2 = Zend_Pdf::load('urlToYourPDF.pdf'); // Loading the statif PDF
$template2 = clone $pdf2->pages[0]; // cloning the page (a must do)
$page2 = new Zend_Pdf_Page($template2); // Creating the second page of the merged PDF with the previous content
$pdf2show->pages[] = $page2; // Adding this page to the final PDF
sendToWebBrowser('title', $pdf2show->render());
sendToWebBrowser is a function sending the PDF content to browser with the title as... title.
$pdf2show->render() produces the merged PDF content as a string.
$extractor = new Zend_Pdf_Resource_Extractor();
$clone_page_to_use_in_any_pdf = $extractor->clonePage($original_pdf->pages[0]);
This is how I did it.
Hope this helps everyone.
TJ
$extractor = new Zend_Pdf_Resource_Extractor();
$page1 = $extractor->clonePage($pdf->pages[$templatePageIndex1]);
$page2 = $extractor->clonePage($pdf->pages[$templatePageIndex2]);
$page1->drawText('Some text...', $x, $y);
$page2->drawText('Another text...', $x, $y);
$pdf = new Zend_Pdf();
$pdf->pages[] = $page1;
$pdf->pages[] = $page2;
Right from the horses mouth.

My experience in merging pdfs :
Zend_Pdf is slow and not efficient for large compilations,
pdftk loose document's bookmarks and crashed if document's size is larger than document merged,
pdflib is really fast and preserve bookmarks, is efficient for large compilations.
Have you tried merging them using the PDF toolkit?
Merging multiple PDFs with it can be achieved using :
pdftk 1.pdf 2.pdf 3.pdf cat output 123.pdf
123.pdf will be the resulting PDF. You can temporarily store the resulting PDF on the server, send it to the browser and remove it when it's no longer needed.
