_TIFFREWRITEFIELD(3tiff)

🌸 NAME 🌸

okay bestie, welcome to the _TIFFREWRITEFIELD(3tiff) manual page from LibTIFF 💅 this one is all about _TIFFRewriteField — rewrite a field in the directory on disk. that's the whole name vibe. periodt.

---

📚 SYNOPSIS 📚

#include <tiffio.h>

int _TIFFRewriteField(TIFF *tif, uint16_t tag, TIFFDataType in_datatype,
tmsize_t count, void *data)

🛠️ DESCRIPTION 🛠️

okay so _TIFFRewriteField() does exactly what it says on the tin: it rewrites a field in the directory on disk, and it does not care about updating the TIFF directory structure in memory. no cap 🫶

Right now it's only supported for a field that already exists in the on-disk directory. So if it's not already there, this is not the function for you, bestie. 🙈

It's mainly used for updating stripoffset / stripbytecount values after the directory is already on disk. iconic behavior for real. ✨

🎯 RETURN VALUES 🎯

It returns zero on failure 😭 and one on success 🎉. that's it. short and sweet.
