PGFHeader(3)

💖 PGFHeader(3) — the libpgf glow-up 💖

okay bestie, sit DOWN, because we're talking about PGFHeader, straight out of libpgf. this is the header struct that holds all the image tea. it's giving "small struct, huge main character energy" and honestly? iconic. 🎀

🌸 SYNOPSIS 🌸

#include <PGFtypes.h>

🫶 Public Member Functions

• PGFHeader () — the constructor, she's the entry point, the door girl, the beginning of everything.

🦋 Public Attributes

• UINT32 width — image width in pixels. the horizontal slay. 📏
• UINT32 height — image height in pixels. the vertical slay.
• UINT8 nLevels — number of FWT transforms. count 'em.
• UINT8 quality — quantization parameter: 0=lossless, 4=standard, 6=poor quality. choose your fighter. 🔥
• UINT8 bpp — bits per pixel.
• UINT8 channels — number of channels.
• UINT8 mode — image mode according to Adobe's image modes. yes, Adobe's. respect the elders.
• UINT8 usedBitsPerChannel — number of used bits per channel in 16- and 32-bit per channel modes.
• PGFVersionNumber version — codec version number: (since Version 7). she's new-ish, she's thriving.

PGFHeader::PGFHeader () [inline]

Definition at line 152 of file PGFtypes.h.

152 : width(0), height(0), nLevels(0), quality(0), bpp(0), channels(0), mode(ImageModeUnknown), usedBitsPerChannel(0), version(0, 0, 0) {}

look at her. every single field zeroed out except mode, which is ImageModeUnknown because she doesn't know herself yet. growth. we love a blank-slate era. 🌱✨
