Where do you get FontDescriptor information for the 14 REQUIRED fonts for PDF files?

Where do you get FontDescriptor information for the 14 REQUIRED fonts for PDF files?

I can find only for Helvetica Normal. The 13 others must be available from somewhere, but from where?

This information must be avialable for other fonts as well, as PDF Reference 1.7 provides partial info for the Garamond font.

The AFM "font metrics" files are widely available. e.g:

http://download.macromedia.com/pub/developer/opentype/tech-notes/Core14_AFMs.zip

Here's the format spec:

https://adobe-type-tools.github.io/font-tech-notes/pdfs/5004.AFM_Spec.pdf

For Type 1 fonts, the AFM information is usually in the .pfm file.

If you want to embed your own TrueType fonts, you'll have to extract the metrics from within the font file itself, in order to fill out the PDF font metadata.
