write_type_one_font.json

The JSON file of the “A Page Set in a Font from 1990” example. A font in Adobe's oldest format, the kind a print shop bought twenty years ago and almost nothing reads any more, cut down to the letters the page draws. Every figure the page states about it was read out of the font itself.

JSON 533 lines

This file is a request: an application sends it over the network to the server, which creates the PDF and sends it back. It creates the same page as the Rust and Python versions of this example. A request names every file it uses, never its content; the call carries the request and the files together. A font the server already holds, such as DejaVuSans, is named with nothing attached. Send the request to the address the API page gives.

The request carries the font itself, which is a font of the customer's own, so this is the one pair on the site rendered for a customer allowed to send one. Every figure the page states about that font the library reads out of the font as it goes — the name it calls itself by, that it carries 62 shapes of which 61 can be reached by a code, the rectangle it states, how thick its strokes are and how far under the line it wants an underline — and the request repeats them as figures written into it. Two weights go with them, what the font weighs on disk and what a throwaway document the library writes to weigh it comes to. All of them move whenever the font is rebuilt; here they are typed in, and would have to be typed in again. On the second page the request copies in the same way what the library reads off the font shape by shape — its matrix, its slant, and for each character of one line its code, its shape and how far it advances — and the two widths that line runs to. The line itself, which that page sets twice in the font, once at the widths the font states and once with a metrics file written over it that widens every shape by a quarter, is not in the request: its second page has nothing where those two lines stand. The library also sets a grey before the closing note and then states black inside the note itself, so the grey paints nothing; the request states no colour there and draws the same page with one instruction fewer.

What This Example Is For

A print shop that has been buying fonts for twenty years owns a collection in Adobe's first font format, bought and paid for, that almost nothing reads any more. Replacing it means buying the same fonts a second time and accepting that a reprint will not quite match the original run. This engine reads that collection, so it keeps working instead of becoming a reason to change nothing.

Each glyph kept is copied byte for byte, still under its own cipher, and the pieces of outline several glyphs share are kept whole. The font's description then names every glyph the file holds.
