HTML2PDF -> Convert is failing with no errors or output available

Technical Support Apryse SDK

I have attached my VERY BASIC sample code to this message. I have verified the HTML is fine but so debugging sake I have reduced it to the VERY simple string below. When I run this code, I get the following error :

Fatal error: PDFNet: An error occurred during linearization: The document contains no pages. in [FULL_PATH_REDACTED]/pdfnet/PDFNetPHP.php on line 15469

I know this is not complex or even reliable, I am just trying to get a Proof of Concept working. Is there a log I can look at or any other kind of output to understand what is happening?

`
PDFNet::Initialize();
HTML2PDF::SetModulePath(dirname(FILE).’/…/vendors/pdfnet’);

$doc = new PDFDoc();
$converter = new HTML2PDF();

$html = “

Heading

Paragraph.

”;

// Add html data
$converter->InsertFromHtmlString( $html );
// Note, InsertFromHtmlString can be mixed with the other Insert methods.
$converter->Convert( $doc );

$this->log( 'REPORTS :: Convert - ’ . $converter->GetHTTPErrorCode() , LOG_DEBUG );

$doc->Save($output_path.’/’.$filename, SDFDoc::e_linearized);
$doc->Close();

`

Thanks

Hi Todd.

Which OS are you running? Is it 64bit?

Also, you can call $converter->GetLog() after calling $converter->Convert(). Also Convert() returns false on failure.

Hi, I’m facing the same problem.

I’m testing the PHP Sample in the wrapers repository.

My code:

$html_sample = "<html><body><h1>Heading</h1><p>Paragraph.</p></body></html>";

$doc = new \PDFDoc();
$doc->InitSecurityHandler();

$converter = new \HTML2PDF();

$converter->InsertFromHtmlString($html_sample);

$converter->Convert($doc);

echo $converter->GetLog();

$doc->Save($output_path, \SDFDoc::e_linearized);
$doc->Close();

\PDFNet::Terminate();

Error:

   Exception
