Error in generated pdf file using zend_pdf under Magento - php

I'm trying to create a PDF file, under a Magento phtml file, this is my code :
$pdf = new Zend_Pdf();
$pdf->pages[] = $pdf->newPage(Zend_Pdf_Page::SIZE_A4);
$page=$pdf->pages[0]; // this will get reference to the first page.
$style = new Zend_Pdf_Style();
$style->setLineColor(new Zend_Pdf_Color_Rgb(0,0,0));
$font = Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_TIMES);
$style->setFont($font,12);
$page->setStyle($style);
$page->drawText('example text here',100,($page->getHeight()-100));
$pdf->render();
$pdf->save('test.pdf','true');
My PDF file is created, but I can't open it with acrobat reader.
When I open it with a text editor and compare it with another simple pdf files, I noticed that in the first line was missing in my generated pdf file. it contains "%PDF-1.4"
How can I add this line programmatically with zend_pdf in my pdf file ?
Thanks for help.

According to the zend manual the second save parameter is only for updating files that already exist. In this case you are creating a new file so don't use that option.
$pdf->save('test.pdf');
PS. This answer is technically an RTM statement.

MPDF create read only pdf file?

I'm using mpdf to download an existing file like this-
$mpdf->Output('my_filename.pdf','D');
I need the file downloaded to be read only. Right now the downloaded files can be opened in word and edited, I wish to avoid that.
TL;DR :
I'm downloading an existing file from my system which my clients can edit by opening in word, need to avoid that.I can't have password protection for the files(client requirement)
Use the SetProtection() function as described here.
$filename = 'filename.pdf';
$html = 'Testing PDF protection.';
$mpdf = new mPDF('utf-8', 'A4-P');
$mpdf->SetProtection(array());
$mpdf->WriteHTML($html);
$mpdf->Output($filename,'D');

Generate PDF from .docx generated by PHPWord

I am creating .docx files from a template using PHPWord. It works fine but now I want to convert the generated file to PDF.
First I tried using tcpdf in combination with PHPWord
$wordPdf = \PhpOffice\PhpWord\IOFactory::load($filename.".docx");
\PhpOffice\PhpWord\Settings::setPdfRendererPath(dirname(__FILE__)."/../../Office/tcpdf");
\PhpOffice\PhpWord\Settings::setPdfRendererName('TCPDF');
$pdfWriter = \PhpOffice\PhpWord\IOFactory::createWriter($wordPdf , 'PDF');
if (file_exists($filename.".pdf")) unlink($filename.".pdf");
$pdfWriter->save($filename.".pdf");
but when I try to load the file to convert it to PDF I get the following exception while loading the file
Fatal error: Uncaught exception 'BadMethodCallException' with message 'Cannot add PreserveText in Section.'
After some research I found that some others also have this bug (phpWord - Cannot add PreserveText in Section)
EDIT
After trying around some more I found out, that the Exception only occurs when I have some mail merge fields in my document. Once I removed them the Exception does not come up anymore, but the converted PDF files look horrible. All style information are gone and I can't use the result, so the need for an alternative stays.
I thought about using another way to generate the PDF, but I could only find 4 ways:
Using OpenOffice - Impossible as I cannot install any software on the Server. Also going the way mentioned here did not work either as my hoster (Strato) uses SunOS as the OS and this needs Linux
Using phpdocx - I do not have any budget to pay for it and the demo cannot create PDF
Using PHPLiveDocx - This works, but has the limitation of 250 documents per day and 20 per hour and I have to convert arround 300 documents at once, maybe even multiple times a day
Using PHP-Digital-Format-Convert - The output looks better than with PHPWord and tcpdf, but still not usable as images are missing, and most (not all!) of the styles
Is there a 5th way to generate the PDF? Or is there any solution to make the generated PDF documents look nice?
I used Gears/pdf to convert the docx file generated by phpword to PDF:
$success = Gears\Pdf::convert(
'file_path/file_name.docx',
'file_path/file_name.pdf');
You're trying to unlink the PDF file before saving it, and you have also to unlink the DOCX document, not the PDF one.
Try this.
$pdfWriter = \PhpOffice\PhpWord\IOFactory::createWriter($wordPdf , 'PDF');
$pdfWriter->save($filename.".pdf");
unlink($wordPdf);
I don't think I'm correct..
You save the document as HTML content
$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'HTML');
After than you read the HTML file content and write the content as PDF file with the help of mPDF or tcPdf or fpdf.
Try this:
// get the name of the input PDF
$inputFile = "C:\\PHP\\Test1.docx";
// get the name of the output MS-WORD file
$outputFile = "C:\\PHP\\Test1.pdf";
try
{
$oLoader = new COM("easyPDF.Loader.8");
$oPrinter = $oLoader->LoadObject("easyPDF.Printer.8");
$oPrintJob = $oPrinter->PrintJob;
$oPrintJob->PrintOut ($inputFile, $outputFile);
print "Success";
}
catch(com_exception $e)
{
Print "error code".$e->getcode(). "\n";
print $e->getMessage();
}

Export a html page to pdf with everything that's written on it, after submit button

I need to export html page to pdf file with everything that's written in it, after I press submit button. It will open new page, with info, and I need for script to automatically make .pdf file (already uploaded to webserver), and get the link from file. Could you give me some easy example (if available, without any plugins, or other features that I must download, I would prefer clean PHP).
Just try this
HTML to PDF with PHP
Using open-source HTML2FPDF project
This solution uses HTML2PDF project (sourceforge.net/projects/html2fpdf/). It simply gets a HTML text and generates a PDF file. This project is based upon FPDF script (www.fpdf.org), which is pure PHP, not using the PDFlib or other third party library. Download [HTML2PDF][1], add it to your projects and you can start coding.
Code example
require("html2fpdf.php");
$htmlFile = "your link";
$buffer = file_get_contents($htmlFile);
$pdf = new HTML2FPDF('P', 'mm', 'Letter');
$pdf->AddPage();
$pdf->WriteHTML($buffer);
$pdf->Output('test.pdf', 'F');

Bloated PDF created by TCPDF

In a web app developed in PHP we are generating Quotations and Invoices (which are very simple and of single page) using TCPDF lib.
The lib is working just great but it seems to generate very large PDF files. For example in our case it is generating PDF files as large as 4 MB (+/- a few KB).
How to reduce this bloating of PDF files generated by TCPDF?
Here is code snippet that I am using
ob_start();
include('quote_view_bag_pdf.php'); //This file is valid HTML file with PHP code to insert data from DB
$quote = ob_get_contents(); //Capture the content of 'quote_view_bag_pdf.php' file and store in variable
ob_end_clean();
//Code to generate PDF file for this Quote
//This line is to fix a few errors in tcpdf
$k_path_url='';
require_once('tcpdf/config/lang/eng.php');
require_once('tcpdf/tcpdf.php');
// create new PDF document
$pdf = new TCPDF();
// remove default header/footer
$pdf->setPrintHeader(false);
$pdf->setPrintFooter(false);
// add a page
$pdf->AddPage();
// print html formated text
$pdf->writeHtml($quote, true, 0, true, 0); //Insert Variables contents here.
//Build Out File Name
$pdf_out_file = "pdf/Quote_".$_POST['quote_id']."_.pdf";
//Close and output PDF document
$pdf->Output($pdf_out_file, 'F');
$pdf->Output($pdf_out_file, 'I');
///////////////
enter code here
Hope this code fragment will give some idea?
You need to see what it is putting inside the PDF. Is it embedding lots of images or fonts?
You can examine the contents with lots of PDFtools. If you have Acrobat 9.0, there is a blog article showing how to do this at http://pdf.jpedal.org/java-pdf-blog/bid/10479/Viewing-PDF-objects
Finally I have managed to solve the problem.
The problem was that by mistake I had inserted a link to email id in the web page that was getting rendered to PDF. By just removing this link the size of the generated PDF went down to just 260 kb!
Thanks everyone who tried to help me out in solving this problem.
Current TCPDF version now includes font subsetting by default to dramatically reduce PDF size.
Check the TCPDF website at http://www.tcpdf.org and consult the official forum for further information.

Add 1 Page to each PDF in folder

I have a folder with 100s of PDF versions of PPT presentations. I also have a one page PDF file that I want to add to the beginning of each PDF file. Is there a way I can do this with PHP? Could I maybe use the Zend Framework?
It certainly can be done by Zend_Framework!
$pdf = Zend_Pdf::load($fileName);
$frontPdf = Zend_Pdf::load('/path/to/template.pdf');
$frontPage = $frontPdf->pages[0];
//prepend our template front page to PDF
array_unshift($pdf->pages, $frontPage);
//update original document
$pdf->save($fileName, true);
I haven't tested the code here but we have an application working on the same principle.
Check the documentation for pages within Zend_Pdf if you have any problems.
