TrueType standard fonts

[kmcclellan]

Attach (recommended) or Link to PDF file here: helloworld-ttf.pdf

Configuration:

• Web browser and its version: NodeJS v14.17.0
• Operating system and its version: Windows 10.0.18363 Build 18363
• PDF.js version: 5d251a3
• Is a browser extension: no

Steps to reproduce the problem:

1. Run the attached PDF through the pdf2png.js example.

What is the expected behavior? (add screenshot)

My company works with PDFs that come from publishers which sometimes use the 14 standard fonts. When they do, they are referenced using the "TrueType" format, instead of the "Type1" that PDF.js implementation in #12726 expects.

If I remove the if (type === "Type1") from this line and rebuild, this issue is resolved. I suspect the exclusion of "TrueType" is just an oversight and that this is an easily fixed bug?
