How to rid of Save As dialog and yellow box in tcpdf - php

When I generate and save a document with a link in it using TCPDF. It is always showing a save as dialog before closing in the pdf reader.
"Do you want to save the changes to file.pdf before closing?"
Also there is a yellow note box in the chrome browser when I hover over the link... as shown in the image below.
My code with problem is like this.
$pdf->writeHTML('link');
However, if my links are empty in my html then there is no problem while closing the pdf, also then there is no yellow box anymore in links. The following code for example is working fine.
$pdf->writeHTML('link');
Here is a complete example to reproduce the problem.
require_once __DIR__.'../../external_classes/TCPDF/tcpdf.php';
$pdf = new \TCPDF();
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('ABC');
$pdf->SetTitle('ABC');
$pdf->SetSubject('ABC');
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, "ABC", "ABC");
$pdf->setPrintFooter(false);
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
$pdf->SetMargins(PDF_MARGIN_LEFT, 10, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
$pdf->SetFont('helvetica', '', 10);
$pdf->AddPage();
$pdf->writeHTML('link');
ob_clean();
$pdf->Output('example.pdf', 'D');
The above example will generate the output like the following image. Which will have both the problems, I have tested both on tcpdf version 5.9.x and 6.2.x.

Okay, found some explanation to both the problems.
1. First Problem: The issue of Save as Dialog
For some reason the tcpdf library is appending my website html at the end of the pdf. I found this out by viewing my pdf in pure text using a text editor.
Using an exist function immediately after output() will fix it.
$pdf->Output('example.pdf', 'D');
exit();
2. Second Problem: The issue of yellow link box in chrome
This is currently an unresolved active issue in chrome. Check this link for example on mPdf forum.

You may resolve the second problem by removing annotations at all.
Create your own class MyTCPDF extends \TCPDF.
Copy to created class "protected function _putannotsobjs()" from tcpdf.php. You will override it.
Change this string in method form
`$annots .= ' /Contents ' . $this->_textstring($pl['txt'], $annot_obj_id);`
enter code here
to
`$annots .= ' /Contents ()';`
Use your class for generation pdf file.
You may put any logic in this method an disable annotations by constant or something else.

tcpdf custom font weird characters

I am trying to use a custom font in my tcpdf file.
$pdf->addTTFfont('../../../fonts/RedHatDisplay-Regular.ttf', '', '', 32);
addTTFfont does:
TCPDF_FONTS::addTTFfont($fontfile, $fonttype, $enc, $flags, $outpath, $platid, $encid, $addcbbox);
This is my Code.
It just gives me weird chars when creating the pdf. The thing is, if I use the RedHatDisplay-Italic.ttf file, it just works perfect. Do you have any ideas what I can do?
So I had the same issue with the Quicksand font. The issue was the font itself (or the resource where I got it from).
I tried multiple resources, because in the past I downloaded Google Fonts (like Lato) and they worked.
So for Quicksand the downloaded font from
https://google-webfonts-helper.herokuapp.com/fonts failed
https://www.fontmirror.com/quicksand worked
CAUTION It looks like if the font already exists, it won't be overwritten by TCPDF_FONTS::addTTFfont so you need to manually get rid of an existing font first (probably from previous adding in vendor/tecnickcom/tcpdf/fonts) .
Other than that, the following code just works fine:
Only call this code once to add the font
<?php
$fontnames = [];
$fontnames[] = TCPDF_FONTS::addTTFfont('fonts/Quicksand Bold.ttf');
$fontnames[] = TCPDF_FONTS::addTTFfont('fonts/Quicksand Regular.ttf');
// Make sure you use the real font name. Different file names may (or may not) produce different font names.
die(print_r($fontnames, 1));
This code then for generating the pdf
<?php
$pdf = new TCPDF('P', 'mm', 'A4');
$pdf->SetFont('quicksand'); // This is the fontname from above
$pdf->AddPage();
$txt = '0123456789 ABCDEFGHIJKLMNOPQRSTUVQXYZ';
// print a block of text using Write()
$pdf->Write(0, $txt, '', 0, 'C', true, 0, false, false, 0);
$pdf->Output('test.pdf', 'I');
exit(1);

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, " ");

How to add new CoreFont to FPDF?

I have tried to add a Font into fpdf by adding this
$pdf = new FPDF('P', 'mm', 'A4');
$pdf->AddFont('calibri','','calibri.php');
$pdf->AddFont('calibri','B','calibrib.php');
$pdf->AddFont('DejaVuSansMono','','DejaVuSansMono.php');
$pdf->AddFont('DejaVuSansMono','B','DejaVuSansMono-Bold.php');
If I use the font courier
$pdf->SetFont('courier', '', 10);
$pdf->Cell(0, 5, 'Hello world', 0, 1);
and preview the generated pdf in the browser, everything is fine.
If I use e.g. calibri the pdf has to be loaded twice to see the result. On first time it comes with an error like:
Error while loading the PDF-Document
If I load it again, it works and if I load it again it wont work and so on...
What could this be?
Could it be that the font file is to large ?
EDIT:
I have to say, this only appears when I call the PDF from my Preview-Script whats actually is build with jquerys ajax. Adding images to the pdf (e.g. 20MB) does not bring up this problem.
And if I preview, open up the pdf in a other tab, and go back to the first tab and load prieview again also dont brings up the problem.
