This is my sample code.
I'm stuck on how to insert images into this.
I would be grateful for any help:
include('autoload.php');
use mikehaertl\pdftk\Pdf;
$dat = "review.png";
$pdf = new Pdf('Josco.pdf');
$pdf->fillForm(['signature'=>$dat ]);
$pdf->saveAs('my.pdf');
I don't know how to fill image in image type field. Please find attached
the pdf file for reference :
[1]: https://drive.google.com/file/d/1wz_mhdCFbG5o_1CgF6VlIJ4Gh70Ne8-E/view?usp=sharing
It is not possible to add image in a pdf using pdftk alone. A possibility would be to use tcpdf or fpdf to generate a pdf file of a blank page with the signature located where you want. Then to use the pdftk stamp function to stamp this generated file on the source pdf

I am trying to convert a multi-page pdf into a single image with all pages in the pdf stacked. I am trying to use the Imagick() class. I found similar questions but none have helped the issue. Here is the code I am using.
$img = new Imagick();
$img->setResolution(300, 300);
$img->readImage(example.pdf);
$img->resetIterator();
$imga = $img->appendImages(true);
$imga->setImageFormat('jpg');
$imga->writeImage("pdfs.jpg");
Only the last page of the pdf is saved in the jpg file the other pages are not.
I am using ImageMagick-7.0.10, PHP 7.3.12 and I am on Windows 10.
You,have to add the index of the pdf page you want.
For the first page :
$img->readImage(example.pdf[0]);
I'm looking to generate animated gif with multipage pdf... not done yet !
I am using php MPDF to generate a PDF files it working fine. But i want to set the height of a pdf page as auto based on content size. Content will come dynamically from DB. Anyone give some idea..
The following is my code
$p = 'P';
$mpdf->_setPageSize(array(200, round($mpdf->y)), $p);
this output also not correct
I have a PDF file with a QR Code. Iuploaded the file on the server folder named "tmp" and now I need to scan and convert this QR via PHP.
I found this library:
include_once('lib/QrReader.php');
$qrcode = new QrReader('/var/tmp/qrsample.png');
$text = $qrcode->text(); //return decoded text from QR Code
print $text;
But this works only for png/jpeg files.
Is there any way to scan PDF ? Is there any way to convert PDF to png only the time that I need ?
Thank you!
First, transform your PDF into an image with Imagick, then use your library to decode the QRcode from it:
include_once('lib/QrReader.php');
//the PDF file
$pdf = 'mypdf.pdf';
//retrieve the first page of the PDF as image
$image = new imagick($pdf.'[0]');
//pass it to the QRreader library
$qrcode = new QrReader($image, QrReader::SOURCE_TYPE_RESOURCE);
$text = $qrcode->text(); //return decoded text from QR Code
print $text;
//clear the resources used by Imagick
$image->clear();
You would want to convert the PDF to a supported image type, OR find a QR code reading library that supports PDFs. IMO the first option is easier. A quick search leads me to http://www.phpgang.com/how-to-convert-pdf-to-jpeg-in-php_498.html for a PDF -> img converter.
Presumably the QR code is embedded in the PDF as an image. You could use a command-line tool such as pdfimages to extract the image first, then run your QRReader library on the extracted image. You might need a bit of trial and error to establish which image is the QR code if there is more than one image in the PDF.
See extract images from PDF with PHP for more detail.
I have file module, where I want to list all files,with thumbnail preview.
as like follows,
I am storing files in storage folder,which is not accessible via http.
So How can I provide thumbnail preview for docs especially image and PDF.
Is there any package availabe in laravel 5.1?
The preview image of a PDF file is usually the first page of the PDF file.
You can use ImageMagick to obtain that first page of the PDF file.
<?php
$imagick = new imagick('sample.pdf[0]'); // 0 specifies the first page of the pdf
$imagick->setImageFormat('jpg'); // set the format of the output image
header('Content-Type: image/jpeg'); // set the header for the browser to understand
echo $imagick; // display the image
?>
You can also output (save the contents of the image in a file) and store it under a thumbnail folder with the PDF name as the file name. like ( sample.jpg )
As for a solution based on laravel, I don't think laravel has any package that can do the same
Though the question was posted quite a long ago but I'm answering because it might helps others. There is a package for generating image from pdf. Pdf to Image. You should have Imagick and Ghostscript installed
I have many PDFs that are generated and uploaded to my server.
The problem is they contain the same page three times (3 pages in total with the same content).
My goal is to edit the PDF with PHP so that it contains only one page.
Is there any library that allows me to simply load a PDF and keep only the first page?
Thank you!
Using FPDI, you can create a function to extract the first page of a PDF file:
function first_page ($path) {
$pdf = new FPDI();
$pdf->AddPage();
$pdf->setSourceFile($path);
$pdf->useTemplate($pdf->importPage(1));
return $pdf;
}
Then output the extracted PDF as you would do with FPDF:
// Extract first page from /path/to/my.pdf
// and output it to browser with filename "MyPDF".
first_page('/path/to/my.pdf')->Output('MyPDF', 'I');
FPDF (http://www.fpdf.org/) or MDPF (http://www.mpdf1.com/mpdf/index.php) are great libraries for work with PDF files. I have experiences only with creating PDF; but I assume that one of those libraries can solve your problem.
Edit: Here is some example with FPDF
