Decoder.h(3)

💖 Decoder.h — the libpgf decoder glow-up 💖

okay bestie, sit down, hydrate, because we're reading Decoder.h(3) from libpgf and it's honestly iconic. this is the header that holds the whole PGF decoder situation. no cap. 🎀

✨ NAME ✨

Decoder.h — the PGF decoder class, fr fr. that's it, that's the vibe. 🦋

---

🌸 SYNOPSIS 🌸

first things first, it pulls in its little friend group of headers, and yes you need all of them:

#include 'PGFstream.h'
#include 'BitStream.h'
#include 'Subband.h'
#include 'WaveletTransform.h'

👑 Classes

• class CDecoder — this is the main character. the PGF decoder itself. 💅
• class CDecoder::CMacroBlock — a macro block, which is a decoding unit of fixed size, and it's uncoded. tiny legend. ✨

🧚 Macros

• #define BufferLen (BufferSize/WordWidth) — how many words fit in one buffer. the math is mathing. 🔥
• #define CodeBufferLen BufferSize — how many words live in the code buffer, and lowkey important: CodeBufferLen > BufferLen. keep that in your notes bestie. 💀

🎀 Macro Definition Documentation 🎀

⭐ #define BufferLen (BufferSize/WordWidth)

number of words per buffer. simple, clean, no drama. it lives at line 39 of file Decoder.h. 🌈

⭐ #define CodeBufferLen BufferSize

number of words in the code buffer — and reminder, CodeBufferLen > BufferLen, so it's giving spacious. it's chilling at line 40 of file Decoder.h. 💖
