Font::TTF::Delta(3)

💖 NAME 💖

Font::TTF::Delta — Opentype Device tables. That's the manual name and the whole assignment, bestie: device tables, periodt. ✨

🌸 DESCRIPTION 🌸

Okay so, each device table corresponds to a set of deltas for a particular point over a range of ppem values. That's the concept, no cap. 💅

• first — the first ppem value in the range. 🎀
• last — the last ppem value in the range. 🦋
• val — this is an array of deltas corresponding to each ppem in the range between first and last, inclusive. Inclusive is doing a lot of work there, iykyk. 💖
• fmt — this is the fmt used when the device table was read (that's log2 of number bits per value). It is recalculated on output. So it's not a forever vibe. ✨

✨ METHODS ✨

🎀 new

Creates a new device table. Fresh table, fresh start, main character energy. ✨

🦋 read

Reads a device table from the given IO object at the current location. It reads right where you are, no teleporting. 💅

💅 out($fh, $style)

Outputs a device table to the given IO object at the current location, or just returns the data to be output if $style != 0. So if $style is zero, it writes; otherwise it hands you the data. No cap. 🫶

⭐ $d->signature()

Returns a content based identifying string for this delta, for compression purposes. Content based, identifying, compression-ready — it's giving signature. 💖

🌈 $d->out_xml($context)

Outputs a delta in XML. XML era, slay. ✨
