TIFFREADRAWTILE(3tiff)

✨ TIFFREADRAWTILE ✨

okay bestie, welcome to the TIFFReadRawTile page from the LibTIFF manual 💖 this one's a little function with big "give me the raw goods" energy and i'm obsessed actually.

---

🌸 NAME 🌸

TIFFReadRawTile — hand over an undecoded tile of data from an open TIFF file. like, no decoding, no processing, just the raw bytes, straight up 🫶

---

🎀 SYNOPSIS 🎀

#include <tiffio.h>

tmsize_t TIFFReadRawTile(TIFF *tif, uint32_t tile, void *buf, tmsize_t size)

she's giving very "short signature, lots of power" fr fr 💅

---

🦋 DESCRIPTION 🦋

So here's the vibe: you call this and it reads the contents of the tile you asked for into a data buffer that you supply yourself — yes, you bring the buffer, she just fills it 🌸

Now, important, do NOT skip this part: the value of tile is a "raw tile number". That means you, the caller, have to take into account whether or not the data is organized in separate planes, aka when PlanarConfiguration = 2. The function is not gonna do that math for you, bestie 😭

And here's the cute part — TIFFComputeTile() does that automatically when it converts an (x,y,z,sample) coordinate quadruple into a tile number ✨ so if you don't wanna think about planes, that's your girl.

Also, if your goal is to read a full tile of data, your data buffer should typically be at least as big as the value returned by TIFFTileSize(). Like, size your buffer properly, don't do the chaotic thing 🙈

---

👑 RETURN VALUES 👑

She tells you the actual number of bytes of data that were placed in buf 🎀 and if something went wrong? TIFFReadRawTile() returns -1. that's the "it's not giving" signal 💀

---

💜 DIAGNOSTICS 💜

Every error message gets directed to the TIFFErrorExtR() routine. so when things go sideways, that's where the tea gets spilled 🍓
