How to load a font in pdflib?

I'm trying to load an .otf font in Php 7.4.7 like this:

  1. Add the resources path which according to the logs looks like it worked:
$pdflib = new pdflib();
$pdflib->set_option('textformat=utf8');
$pdflib->set_option('SearchPath={{fullpath/to/my/fonts}}');

the log show up to this point no errors:

[New category:resource "SearchPath:fullpath/to/my/fonts"]
  1. But when loading the font like this:
$font = $pdflib->load_font("My-Font-Regular", "unicode", "embedding");

I get this error:

[Last exception 2516 in load_font]["Font 'My-Font-Regular' with encoding 'unicode': Font file (AFM, PFM, TTF, OTF etc.) or host font not found"]

I have tried utf-8 as encoding, giving full path when adding the search path and when loading the font, single and double curly braces when setting the search path but I could make more progress.

Also tried with no success:

$pdflib->set_option("stringformat=utf8");

I couldn't find any documentation for accepted encodings and the function it's not even described in the pdflib provided docs.

Any help would be greatly appreciated.

in general this looks fine, but there are a few potential pitfalls when using the extension based search:

  • the font file do not have one of the supported file extensions (like .ttf, .otf etc.)
  • the font name you use is different to font file base name. In your case, My-Font-Regular. Do your font file have this name with the extension .otf => My-Font-Regular.otf
  • the path fullpath/to/my/fonts (or a sub directory) has wrong read permissions for your PHP process.
  • when working on Windows, please take care, that you apply a complete absolute path. (see PDFlib 9 Tutorial, chapter 2.8 PHP Binding section File name handling in PHP for details.)

Please see PDFlib 9 Tutorial, chapter 6.4.4 Searching for Fonts section Extension-based search for font files for a detailed explanation.

As you have already enabled logging, you can enable more details by adding classes {filesearch=3}. Please see PDFlib 9 API Reference, chapter 1.3 Logging for more details. This might give you more details. And I'm sure, opening a Support case at PDFlib with sharing more details might also be an option.
