I would like to add a simple hidden data (could be comment or something) for generate pdf file through fpdf library. I need simple protection of authenticity, that this file has been generated through my application .
Thanks for answers
Option 1 :
You can set the pdf with below. (the properties only viewable at pdf reader)
$pdf->SetTitle("Any Title");
$pdf->SetAuthor("Any Author");
$pdf->SetSubject("Any Subject");
$pdf->SetCreator("Any Creator");
I think you need extend your FPDF class to FPDFP (Protection), If not will be able to change the setting.
Option 2 :
using Watermark class extension.
Option 3 :
generate some non-understand wording as your pdf signature at bottom page. If you don't want print out at the paper, set the text color. (look like cheat way but simple)
$pdf->SetTextColor(255,255,255);//Set to White color
$pdf->Cell(20,10,'onlyme_understand_signature',1,1,'C');
$pdf->SetTextColor(0,0,0);//Set to Black color
I don't see any way to add metadata (XMP) data using FPDF. TCPDF can do it:
TCPDF::setExtraXMP($someCustomString);
The only way to do this that I see (it's far from waterproof but adding something to XMP also isn't waterproof) is to set the creator of the file correctly using:
SetCreator(string creator [, boolean isUTF8])
This will allow you to have a specific string for who created the file which you could easily test for later. As most PDF consumers leave the creator string alone once it's there, this might be good enough for your purposes.

I am trying to convert a DOCX file to PDF with PHPWord. When I execute the script it looks like that some style elements are not converted. In the DOCX file I have one image, two tables with border 1px and hidden borders and I am using Tabs.
When I execute the script I get a PDF file without the image, all the Tabs are replaced with Space and all the tables have a border 3px.
Does someone know why I am missing these styles?
Here is my script:
while ($data2 = mysql_fetch_array($rsSql)){
$countLines=$countLines+1;
$templateProcessor->setValue('quantity#'.$countLines, $data2['quantity']);
$templateProcessor->setValue('name#'.$countLines, $data2['name']);
$templateProcessor->setValue('price#'.$countLines, "€ " .$data2['price'] ."");
}
\PhpOffice\PhpWord\Settings::setPdfRenderer('./dompdf');
\PhpOffice\PhpWord\Settings::setPdfRendererPath('./dompdf');
\PhpOffice\PhpWord\Settings::setPdfRendererName('DOMPDF');
$temp_file = tempnam(sys_get_temp_dir(), 'Word');
\$templateProcessor->saveAS($temp_file);
$phpWord = \PhpOffice\PhpWord\IOFactory::load($temp_file);
$xmlWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord , 'PDF');
$xmlWriter->save('result.pdf');
header("Content-type:application/pdf");
header("Content-Disposition:attachment;filename='result.pdf'");
readfile("result.pdf");
After a look on the source code, it seems that PHPWord previously converts the document into an HTML representation before letting it be saved it into PDF by dompdf, another converter.
That's what the opened issue #1139 confirms, moreover it deals with styles missing:
The PDF writers being used are taking in the HTML output, which also lacks the styling. The classes are being defined in the <style> tag, but they are just not being used.
Also the last message adds:
This still seems to be an issue. html and pdf outputs do not replicate the some styles in docx (header / footers).
Concerning your border problem, another SO question shows a similar issue in a conversion HTML -> PDF. A solution was to edit the CSS style, which you obviously cannot perform in your sample code, unless you proceed to pre-convert into HTML.
In conclusion, you may not solve your problem in the short term. If you won't be a part of the dev team, you could submit bug reports to them (and not to dompdf, since it's an HTML-to-PDF converter and they are outside the scope). Github lets you to add DOCX files to the issue report.
Alternatives
You could check out a SO question 204860 about server sides PDF editing library. Below two alternatives, one is free software, the other is closed source and priced.
LibreOffice
Another way is to use LibreOffice in headless mode (command line execution without interface):
libreoffice --headless --convert-to pdf <filename_to_convert>
A PHP wrapper for LibreOffice, Office Converter is also available here if you don't want to bother using libreoffice through exec().
Check if LibreOffice conversion will suit your needs (it may not cover all cases, but be satisfying your scope).
Aspose
The best converter I ever used at work is Aspose, an API covering Documents with Aspose.Words package, Worksheets with Aspose.Cells, Presentations with Aspose.Slides and so on. But it's closed-source and pretty expensive (and you'll pay for updates if you want them after your license expiration).
There is a way to use it in PHP through Java (Aspose.Words and Aspose.Cells) or .NET (Aspose.Words same seems to go with Aspose.Cells).
I'm attempting to create a thumbnail of a multi-page PDF document using Gmagick, however I only want the first page of the PDF, not all of them.
$thumb = new Gmagick();
$thumb->readImage("/path/to/file/document.pdf");
$thumb->setImageFormat('JPG');
$thumb->thumbnailimage(198, 255);
$thumb->writeImage("/path/to/file/document.jpg");
$thumb->destroy();
This code works, however instead of creating just 1 image 'document.jpg' it creates 'document.jpg.0', 'document.jpg.1', 'document.jpg.2', etc. for all of the PDF pages. I could go and delete all the additional pages and rename the first image just 'document.jpg' but that seems a bit hacky to me.
Is there a way to designate just the first page of the PDF? I can't seem to find anything, and Gmagick's documentation seems to be lacking.
Pekka is right. GraphicsMagick - just like ImageMagick - accepts the special pdf file name notation filename.pdf[0] which would render only the first page, filename.pdf[1] for the second page, and so on.
I am using PDF Jam for manipulating pdf. I need to add a text line at the bottom of generated file. I tried it but not able to made it.
Can anybody guide me how to do it?
I did in my php code as
$command = '-----------------';
exec($command);
As you know, PDFJAM is for manipulating pds. It is a small collection of shell scripts which provide a simple interface to much of the functionality of the excellent pdf pages. See the Ubuntu Manual
pdfjam - A shell script for manipulating PDF files
You should create your sheet as your doing (5x6) and create a separate sheet of minimal page size with required information than merge both the file into one.
Else in first step create your sheet and use pdflib to add text as second step. It very good tool. I hope its a good solution of your problem.
I love pdftk and so wanted to find a solution using that. The following worked for me.
pdfjam --preamble '\usepackage{fancyhdr} \topmargin 85pt \oddsidemargin 140pt \cfoot{\thepage}' --pagecommand '\thispagestyle{plain}' --landscape --nup 2x1 --frame false --clip true --trim ".5in 0.5in 0.5in .65in" --delta '-0.25in 0' tmp.pdf
I cribbed it from: Page Numbering with the "{page} of {pages}", removing the "of pages" part.
Command converts pdf to 2x1, trims margins, and crops. Output is landscape.
\topmargin and \oddsidemargin seem to tell pdflatex where to put the numbers.
I want to modify a PDF document with PHP. I found the libs FPDF and FPDI which allows to create and modify PDF files. Here is my very simple code:
<?php
require_once('include/fpdf.php');
require_once('include/fpdi.php');
// initiate FPDI
$pdf = new FPDI();
// add a page
$pdf->AddPage();
// set the sourcefile
$pdf->setSourceFile('input.pdf');
// import page 1
$page1 = $pdf->importPage(1);
// insert the page
$pdf->useTemplate($page1);
// now write some text above the imported page
$pdf->AddFont('calibri');
$pdf->SetFont('calibri','',11);
$pdf->Write(0, "This is just a simple text");
header("Content-Type: application/pdf");
$pdf->Output();
That works very well, but I see that the inserted text adds something like a reference to the system font instead of the already embedded font. How can I simply reuse the embedded font?
If that is not possible with that libs feel free to point me to a third free lib.
I know that I can just use characters which are already used, but this is no problem in my special case. I have checked that all possible characters are used in the right case sensitivity.
I bet your embedded font from the imported PDF page is not called calibri. (Lower-case only spelling of fontnames in PDFs is very rare.)
And I also bet, that the PDF will not have Calibri embedded as a full set. It's rather likely that it is a subset only. And as a subset, the fontname will be composed of a random 6 letter uppercase prefix + the original font name, like this:
AXBTZV+Calibri
You have to find that exact name and try with this. (However, I'm not sure if how your PHP library works, if it can do that at all, and if it would handle the modification of the PDF text writing code in the correct way. Gimme the PDF and I most likely can do it in a Text Editor, though...)
Reusing fonts in PDFs is mostly not possible since only the characters that are used in the PDF are stored. So if you never used an uppercase W in your PDF template and want to add text with one, then it cannot be displayed.
This does not answer your question but rather tells you not to try it at all.
I have a pdf file of a logo, about 1"x2" in dimension. Can anybody provide the code snippet to import that PDF logo into another PDF file using the Zend_PDF API's?
Ideally, I'd like to be able to place it like the PNG, TIFF or JPG objects with the Zend_Pdf_Image object.
In other words, I want to be able to place the little 1x2" pdf document on top of a 8.5x11" page, not use the original pdf as a background.
Thanks!
It looks like as of this date, there's no way to do it using the Zend_PDF API's. The Zend_Pdf_Page class has a drawContentStream() which looked promising, but when I checked into it, the method body was empty. Maybe a later release of the API will support it.
So, if you want place another PDF inside another dynamically generated PDF document like an image, use FPDI + FPDF/TCPDF.
$pdf = & new FPDI ('P', 'in', 'Letter' );
$pagecount = $pdf->setSourceFile ( APP . 'logo.pdf' );
$tplidx = $pdf->importPage ( 1, '/MediaBox' );
$pdf->addPage ();
$pdf->useTemplate ( $tplidx, 1, 1 );
$pdf->Output ( 'output.pdf', 'F' );
I believe you can clone a page --like a template. Not sure if this is enough for you, it does look like the preferred way to do things. Of course, if you have a pdf that you want to add a, say, watermark, to, uhh, this is clearly insufficient --but in this case a hi-res png would probably suffice.
Not what you asked for, but probably what you need (:
Convert the smaller logo pdf to a TIFF/PNG/WhatEver (using, for example, imagemagick's convert, or the GIMP). Then, place this image with the normal Zend API.
This conversion could also be done on the fly, using the Imagick php class, I would imagine.
