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.

Previously i was working with dompdf in laravel application to generate invoices.. Its taking time in generating invoices but working perfectly . Below is the code of dompdf to generate invoice by just sending the view.
PDF::setOptions(['dpi' => 150, 'defaultFont' => 'sans-serif']);
// pass view file
view()->share('account_invoice',$account_invoice);
view()->share('account_invoice_item',$account_invoice_item);
$pdf = PDF::loadView('admin/invoice/InvoiceTemplate/template');
But now i am working with FPDF. Is there anything like dompdf to pass view to generate PDF.
$pdf = new FPDF();
View::make('admin/invoice/InvoiceTemplate/template');
I know my code is incorrect for FPDF but any idea how can i pass view to FPDF to generate pdf so i can send it by attactment.
It looks like your goal is to dump raw html onto the pdf and have it be formatted accordingly? Take a look at this tutorial, it might help, but I'd actually recommend a different approach.
Basically, fpdf is has no html writer built in, at least none as far as I'm aware. So I'd recommend a pdf writer with better out of the box support for your needs. Take a look at Snappy and wkhtmltopdf. With Snappy and wkhtmltopdf you can pretty easily generate pdfs on the fly by passing it html, as you're attempting to in your examples.
<?php
use Knp\Snappy\Pdf;
$snappy = new Pdf('/path/to/wkhtmltopdf');
$snappy->generateFromHtml(View::make('admin/invoice/InvoiceTemplate/template'), '/tmp/invoice.pdf');
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.

Does anyone know of a good method for editing PDFs in PHP? Preferably open-source/zero-license cost methods. :)
I am thinking along the lines of opening a PDF file, replacing text in the PDF and then writing out the modified version of the PDF?
On the front-end
If you are taking a 'fill in the blank' approach, you can precisely position text anywhere you want on the page. So it's relatively easy (if not a bit tedious) to add the missing text to the document. For example with Zend Framework:
<?php
require_once 'Zend/Pdf.php';
$pdf = Zend_Pdf::load('blank.pdf');
$page = $pdf->pages[0];
$font = Zend_Pdf_Font::fontWithName(Zend_Pdf_Font::FONT_HELVETICA);
$page->setFont($font, 12);
$page->drawText('Hello world!', 72, 720);
$pdf->save('zend.pdf');
If you're trying to replace inline content, such as a "[placeholder string]," it gets much more complicated. While it's technically possible to do, you're likely to mess up the layout of the page.
A PDF document is comprised of a set of primitive drawing operations: line here, image here, text chunk there, etc. It does not contain any information about the layout intent of those primitives.
There is a free and easy to use PDF class to create PDF documents. It's called FPDF. In combination with FPDI (http://www.setasign.de/products/pdf-php-solutions/fpdi) it is even possible to edit PDF documents.
The following code shows how to use FPDF and FPDI to fill an existing gift coupon with the user data.
require_once('fpdf.php');
require_once('fpdi.php');
$pdf = new FPDI();
$pdf->AddPage();
$pdf->setSourceFile('gift_coupon.pdf');
// import page 1
$tplIdx = $this->pdf->importPage(1);
//use the imported page and place it at point 0,0; calculate width and height
//automaticallay and ajust the page size to the size of the imported page
$this->pdf->useTemplate($tplIdx, 0, 0, 0, 0, true);
// now write some text above the imported page
$this->pdf->SetFont('Arial', '', '13');
$this->pdf->SetTextColor(0,0,0);
//set position in pdf document
$this->pdf->SetXY(20, 20);
//first parameter defines the line height
$this->pdf->Write(0, 'gift code');
//force the browser to download the output
$this->pdf->Output('gift_coupon_generated.pdf', 'D');
If you need really simple PDFs, then Zend or FPDF is fine. However I find them difficult and frustrating to work with. Also, because of the way the API works, there's no good way to separate content from presentation from business logic.
For that reason, I use dompdf, which automatically converts HTML and CSS to PDF documents. You can lay out a template just as you would for an HTML page and use standard HTML syntax. You can even include an external CSS file. The library isn't perfect and very complex markup or css sometimes gets mangled, but I haven't found anything else that works as well.
Don't know if this is an option, but it would work very similar to Zend's pdf library, but you don't need to load a bunch of extra code (the zend framework). It just extends FPDF.
http://www.setasign.de/products/pdf-php-solutions/fpdi/
Here you can basically do the same thing. Load the PDF, write over top of it, and then save to a new PDF. In FPDI you basically insert the PDF as an image so you can put whatever you want over it.
But again, this uses FPDF, so if you don't want to use that, then it won't work.
Zend Framework can load and edit existing PDF files. I think it supports revisions too.
I use it to create docs in a project, and it works great. Never edited one though.

Tcpdf is also a good liabrary for generating pdf in php
http://www.tcpdf.org/
We use pdflib to create PDF files from our rails apps. It has bindings for PHP, and a ton of other languages.
We use the commmercial version, but they also have a free/open source version which has some limitations.
Unfortunately, this only allows creation of PDF's.
If you want to open and 'edit' existing files, pdflib do provide a product which does this this, but costs a LOT
<?php
//getting new instance
$pdfFile = new_pdf();
PDF_open_file($pdfFile, " ");
//document info
pdf_set_info($pdfFile, "Auther", "Ahmed Elbshry");
pdf_set_info($pdfFile, "Creator", "Ahmed Elbshry");
pdf_set_info($pdfFile, "Title", "PDFlib");
pdf_set_info($pdfFile, "Subject", "Using PDFlib");
//starting our page and define the width and highet of the document
pdf_begin_page($pdfFile, 595, 842);
//check if Arial font is found, or exit
if($font = PDF_findfont($pdfFile, "Arial", "winansi", 1)) {
PDF_setfont($pdfFile, $font, 12);
} else {
echo ("Font Not Found!");
PDF_end_page($pdfFile);
PDF_close($pdfFile);
PDF_delete($pdfFile);
exit();
}
//start writing from the point 50,780
PDF_show_xy($pdfFile, "This Text In Arial Font", 50, 780);
PDF_end_page($pdfFile);
PDF_close($pdfFile);
//store the pdf document in $pdf
$pdf = PDF_get_buffer($pdfFile);
//get the len to tell the browser about it
$pdflen = strlen($pdfFile);
//telling the browser about the pdf document
header("Content-type: application/pdf");
header("Content-length: $pdflen");
header("Content-Disposition: inline; filename=phpMade.pdf");
//output the document
print($pdf);
//delete the object
PDF_delete($pdfFile);
?>
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.
