Hi there, Let say i have a document just for an example with a width of 100 I create 6 cells 1st cell = 10 width 2nd cell = ? 3rd cell = 20 width 4th cell = 20 width 5th cell = 20 width 6th cell = 20 width I just want to ask if is it possible that the 2nd cell can adjust its width given the width of other cells just to fit the whole width of a document? for example the above widths will have a total of 90 so the 2nd cell should automatically adjust to 10 since the total width of document is 100 Is it possible?

Hi,

First of all: thank you for your continuous efforts on TCPDF/tc-lib-pdf. I've been looking into what library I should be using and yours seems to be having quite some features.

I've tried using tc-lib-pdf however I didn't got it to work and I'm unsure what I'm doing wrong. When trying TCPDF I had no issues and could rather quickly find my way into creating a basic PDF. However I wonder what's the use of learning the "old" TCPDF when you're building tc-lib-pdf as it's successor(I'd rather immediately go that way). I've been trying to find some basic example on how to use your code but that fails.

IMHO I think the examples are great for TCPDF but the site is misleading in refering to the tc-lib-pdf repo by default (I only noticed after a while that that is why the examples didn't work). Also: the installation notes seem very limited(actually hit the API limiter on github with the instructions on the site). I understand you want to make use of some technologies like composer. However for someone who's not been working with PHP that much recently it's unclear on what steps are now needed to make actual use of your project(for example the site refers to creating a composer.json but not if you'd need to execute anything else like: composer install).

My actual question is if you'd be so kind to make a basic project example using tc-lib-pdf. So for example: Get the git repository: git clone ... Get the dependencies; composer install Create a file: example.php Add the following to example.php to include tc-lib-pdf to your project (to make use of the namespaces, ...): ... You can create a basic PDF like this: ... To create and view the docs do; ...

And maybe clearly differentiate on the website between TCPDF and tc-lib-pdf (with the different repo names).

I think it'd help a lot of people in getting on the new tc-lib-pdf wagon.

Thanks in advance for your continuous efforts!

I'm generating PDF files on the fly with user content which could contain emoji-characters. Currently I'm using a custom font and emoji-characters don't get displayed in the PDF (some are totally hidden, some are printed in unknown characters).

To be honest, I don't know exactly where to start looking. Should my custom font include the emoji-characters? Or can I do something else to include them? I've tried both MultiCell and writeHTMLCell.

Thanks!

Please consider raising the minimum requirements for your project to for example PHP 7.2. You are creating a new library and there is no reason to support PHP versions, which haven't been supported for a year or in case of 5.6, several years. Whoever is using your library also is starting over and I don't see anyone running your code on something lower than PHP 7.2, maybe even just PHP 7.4, especially considering that you don't have a date for a release yourself yet.

Hi, does tcpdf support datauri in writehtml src tags?

(i'm using elibyy/tcpdf-laravel)

i don't want to store the signatures from my clients on my server so instead i've tried to store them as datauri's in my db.

example code:

$html .='<img src="'.$data_uri.'" width="300">';
PDF::Writehtml($html);

i get an empty space where the signature should come.

i can achieve this with PDF::Image('a'.$datauri) however its not responsive to my pdf then..

Thanks in advance

I see that TCPDF is now considered obsolete but seeing as this library is still in development I'm wondering if you would accept PRs on the old library that update for PHP 7.3 compatibility?

Thanks for all the amazing work. I'm a big fan of TCPDF and use it in multiple projects, and I'd love to use an more up to date library. Is this library useable for simple needs ? Is there a roadmap or a backlog where we could pick tickets if we want to help ?

Hello! Thanks for your work on this package.

I have an issue where the images seem to have some transparency instead of rendering full color,

Please see page 2 of this pdf, http://customizer.prolook.com/design_sheets/A6D6B362-32E6-5154-93EB-59FC24258811.pdf

Also theres a small thumbnail of a mascot on page 5, the appear to have some king of transparency setting.

The full color of the image which is also the same as the source image being used by the pdf is at https://s3-us-west-2.amazonaws.com/uniformbuilder/uploads/staging/884ab11e1d16911d3d41aae1334ca4b9.png

Thanks! Any help would be really appreciated.

I use the latest version of TCPDF looking forward to the new release, I have a problem with the borders of an HTML table as described in http://stackoverflow.com/questions/38505197/tcpdf-html-table-border-not-render-correctly there is a solution or do I have to wait for the new version?

In the example code, $this->outlines is not declared and throws a Exception:

Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in ..../vendor/tecnickcom/tc-lib-pdf/src/Output.php:757

Hi Guy!

Really thank you for make PDF library. It is very useful.

I have problem when make pdf with add timestamp and signature for pdf. Do you know any document relative with timestamp and signature function in PDF. Example

Hope you reply to me. Thanks so much

Hi,

Could you please add a simple example where you print some text onto a page?

Should I set the font first? I get an empty page when I try something like this:

$pdf = new Tcpdf('mm', true); $page01 = $pdf->page->add(); $pdf->page->setX(10); $pdf->page->setY(10); $pdf->page->addContent('This is simple text');

What am I doing wrong? Your help would be much appreciated.

Hi I started to use your library today and I've encounter 3 issues :

I'm using this to configure :

        foreach ($documents as $invoiceNumber => $document) {

            $pdf = new Tcpdf();
            $pdf->setCreator('client');
            $pdf->setAuthor('[email protected]');
            $pdf->setTitle($invoiceNumber);
            $pdf->setSubject('invoice');
            $pdf->setKeywords("facture, {$invoiceNumber}");
            $pdf->page->add();
            $pdf->page->addContent($document);

            file_put_contents("../var/invoices/{$invoiceNumber}.pdf", $pdf->getOutPDFString());
        }

first error I encountered:

Warning: Undefined property: Com\Tecnick\Pdf\Tcpdf::$outlines

And yes of course the property is defined nowhere so I added it on MetaInfo.php#130 :

protected $outlines = [];

Then the second error kicked in :

Warning: Undefined property: Com\Tecnick\Pdf\Tcpdf::$signature

so I tried to add in Output#58 : it's weird that this array is not defined anywhere by the way

    protected $signature = [
        'appearance' => [
            'empty' => []
        ]
    ];

But then I got :

Warning: Undefined variable $out (in getOutSignatureFields)

And of course the method here is completely messed up. $out not defined out of the foreach for a property that is not existing.

I tried (without knowing if I was doing any good) to modify getOutSignatureFields in Output.php#876

    protected function getOutSignatureFields()
    {
        $out = '';
        foreach ($this->signature['appearance']['empty'] as $key => $esa) {
            $page = $this->page->getPage($esa['page']);
            $signame = $esa['name'].sprintf(' [%03d]', ($key + 1));
            $out .= $esa['objid'].' 0 obj'."\n"
                .'<<'
                .' /Type /Annot'
                .' /Subtype /Widget'
                .' /Rect ['.$esa['rect'].']'
                .' /P '.$page['n'].' 0 R' // link to signature appearance page
                .' /F 4'
                .' /FT /Sig'
                .' /T '.$this->getOutTextString($signame, $esa['objid'])
                .' /Ff 0'
                .' >>'
                ."\n".'endobj';
        }
        return $out;
    }

Now, I've got no error, but PDF is empty.

Can you assist ?

External images with presigned url from amazon s3 service fail to load. URL example.

https://siiam-chpo-2.s3.us-east-2.amazonaws.com/control_patrimonial/parque_vehicular/test-image-624614388f78c060564166.jpg?X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Algorithm= AWS4-HMAC-SHA256 & X-Amz-Credential = AKIAUKF63TAAV2JKSJR6% 2F20220402% 2Fus-east-2% 2Fs3% 2Faws4_request & X-Amz-Date = 20220402T024413Z & X-Amz-SignedHeaders = host & X-Amz-Expires = 3600 & X-Amz-Signature = 58fdf6462adce4d2837039a484bb7416b957f4b29e8541e9612c97af8bab3217

The problem is the url_exists method of the tcpdf_static.php class, with this type of pre-signed url it always returns the http code 403. The images are displayed without problem in html templates in the img tags. If I intentionally return code 200 in that function, the image is displayed correctly in the pdf.

The solution I found is to convert the images to base64 and then pass it to the Image function as in the example. https://tcpdf.org/examples/example_009/

I had downloaded tcpdf and here you are - I have a problem.

simple html code

<p>Это тест</p>

works all right []1

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor('Nicola Asuni');
$pdf->SetTitle('TCPDF Example 002');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');

$pdf->setPrintHeader(false);
$pdf->setPrintFooter(false);

$pdf->SetDefaultMonospacedFont('freeserif');

$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);

$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);

$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);

$pdf->setFontSubsetting(true);

$pdf->SetFont('freeserif', '', 12, '', true);

$pdf->AddPage();

//simple html being shown ok
$pdf->writeHTML('<p>Это тест</p>');

$pdf->Output('example_002.pdf', 'D');

but when I try to convert my html page cyrillic symbols replaced by question marks "?"

$pdf->writeHTML($html);
