TIFFWRITETILE(3tiff)

✨ TIFFWRITETILE ✨

okay bestie, gather round, because we're talking about a libtiff function from the 3tiff manual section and honestly? it's giving main character energy 🎀

TIFFWriteTile — encode and write a tile of data to an open TIFF file. that's the whole vibe. let's get into it 💅

---

🌸 SYNOPSIS 🌸

#include <tiffio.h>

tmsize_t TIFFWriteTile(TIFF *tif, void *buf, uint32_t x, uint32_t y,
                       uint32_t z, uint16_t sample)

like. look at those arguments. six of them. she's thorough 💖

---

💖 DESCRIPTION 💖

so here's the tea 🫖 — TIFFWriteTile writes the data for the tile containing the coordinates you specified. yes, the tile containing those coordinates, not some random tile, not a tile of your choosing, the one that matches. slay.

the data sitting in buf are (potentially) compressed, and they get written to the file you indicated — normally being appended to the end of the file. ok so important thing, bestie, do NOT forget this: the buffer must contain an entire tile of data. the whole thing. no half tiles, no "eh it's close enough". the whole tile, periodt. 😤

and how do you know how big that tile even is?? great question, love that for you. applications should call TIFFTileSize() to find out the size (in bytes) of a tile buffer. call her. she'll tell you. 🧚

now the parameters, let's break them down one by one:

• x and y — these are always used by TIFFWriteTile(). every time. no exceptions. iconic behavior honestly 👑
• z — only used if the image is deeper than 1 slice, aka when ImageDepth > 1. otherwise she's just sitting there, decorative 💅
• sample — used only if data are organized in separate planes, aka when PlanarConfiguration = 2. if your planes aren't separate, this one's just vibing ✨

---

🌈 RETURN VALUES 🌈

TIFFWriteTile() returns -1 if it detects an error 😭 — otherwise, the number of bytes in the tile is returned. so like, if you get a positive number, we ate. if you get -1, something went wrong and we're crying in the club 💀

---

🔥 DIAGNOSTICS 🔥

all error messages are directed to the TIFFErrorExtR() routine. every single one. she doesn't keep secrets, she tells TIFFErrorExtR() everything 🫶
