Page: access "default" font/size

[akomm]

Page's drawText has options font & size. If not specified, defaults are used.

Problem: when implementing layouting and measuring, I don't see any documented way of retrieving the defaults in case I want to preserve the optionality when writing the text. So I need to wrap the API with non-optional font & size, so that measurment is possible.

How does PDF-Lib "pick" the defauls. How can I access them?

Figured it out:

pdf-lib/src/api/PDFPage.ts

Lines 1552 to 1558 in 49b8e5e

	private getFont(): [PDFFont, PDFName] {
	if (!this.font || !this.fontKey) {
	const font = this.doc.embedStandardFont(StandardFonts.Helvetica);
	this.setFont(font);
	}
	return [this.font!, this.fontKey!];
	}

Used internally if no font was set.

I feel kind of bad mimic this "internal" behavior on my side to preserve the optionality. Why is getFont actually private? Same applies to fontSize.
