Method getDataTm return empty array

• PHP Version: 7.3
• PDFParser Version: latest

Description:

Hi,

I'm using the latest version of smalot pdf parser, and trying to use getDataTm on the attached PDF, but always return an empty array.

PDF input

Expected output & actual output

Code

include('vendor/autoload.php');
$config = new Smalot\PdfParser\Config();
 
$config->setDataTmFontInfoHasToBeIncluded(true);

// use config and parse file
$parser = new Smalot\PdfParser\Parser([], $config);
$pdf = $parser->parseFile('test.pdf');
 
$data = $pdf->getPages()[0]->getDataTm();

var_dump($data);

test.pdf

Reproduce the report with vendor/autoload.php, the Parser and Config setup shown, and the attached test.pdf. Start at getDataTm() on the first parsed page and trace why it returns an empty array when setDataTmFontInfoHasToBeIncluded(true) is enabled. Done means the reported PDF produces the expected non-empty data.
