TIFFREADFROMUSERBUFFER(3tiff)

💖 TIFFREADFROMUSERBUFFER 💖

okay bestie, so this one is from the LibTIFF crew — it lives in section 3tiff of the manual, and it's literally the glow-up version of decoding when you already have the data. no cap. 🦋

✨ NAME ✨

TIFFReadFromUserBuffer — decode data using an user defined buffer 💅

---

🌸 SYNOPSIS 🌸

#include <tiffio.h>

int TIFFReadFromUserBuffer(TIFF *tif, uint32_t strile, void *inbuf,
tmsize_t insize, void *outbuf, tmsize_t outsize)

---

🎀 DESCRIPTION 🎀

so the vibe here is: you hand over your input buffer, that's inbuf with its size insize, and it decompresses that whole thing straight into outbuf, which is outsize big. that's it. that's the function. 🫶

it's giving "replacement era" for TIFFReadEncodedStrip() and TIFFReadEncodedTile() — specifically for when you, the user, can provide the buffer for the input data yourself. like, for example, when you wanna avoid having libtiff read the strile offset/count values out of the StripOffsets / StripByteCounts arrays, or the TileOffsets / TileByteCounts arrays. you already have that info, so why make libtiff go digging? exactly. 💀

⚠️ okay but listen — the inbuf content must be writable (if bit reversal is needed). do not come crying to me if you passed a const buffer. that's on you, bestie. 😭

⭐ RETURN VALUES ⭐
