TIFFBUFFER(3tiff)

💖 TIFFBUFFER 💖

okay bestie, welcome to TIFFbuffer, aka the I/O buffering control routines from the LibTIFF manual. yes she's a 3tiff girlie. let's get into it ✨

🌸 NAME 🌸

TIFFbuffer — I/O buffering control routines 🎀

---

✨ SYNOPSIS ✨

#include <tiffio.h>

int TIFFReadBufferSetup(TIFF *tif, void *buffer, tmsize_t size)

int TIFFWriteBufferSetup(TIFF *tif, void *buffer, tmsize_t size)

---

💅 DESCRIPTION 💅

so here's the tea ☕ — these routines exist so that you, the client, can have control over the I/O buffers the library uses. and like, real talk: applications need never use these routines. they're not for everyone, they're for the "intelligent clients" — the ones who wanna optimize memory usage and/or eliminate potential copy operations that can happen when you're working with images that have data stored without compression. main character energy only, periodt 👑

🦋 TIFFReadBufferSetup() 🦋

this one sets up the data buffer used to read raw (encoded) data from a file. if the specified pointer is NULL (zero), then a buffer of the appropriate size gets allocated for you. otherwise?? the caller must guarantee that the buffer is large enough to hold any individual strip of raw data. no pressure bestie, just a guarantee 🙈

it returns a non-zero value if the setup was successful and zero otherwise. so like, truthy = slay, falsy = 😭.

🧚 TIFFWriteBufferSetup() 🧚

this one sets up the data buffer used to write raw (encoded) data to a file. if the specified size is -1, then the buffer size is selected to hold a complete tile or strip, or at least 8 kilobytes — whichever is greater. cute, right? 🌈

and if the specified buffer is NULL (zero), then a buffer of the appropriate size is dynamically allocated.

it returns a non-zero value if the setup was successful and zero otherwise. same vibe check as her sister function 💜

💀 DIAGNOSTICS 💀

these are the messages that show up when things go sideways. they use printf-style formatting, so keep the format strings exactly as they are:

• %s: No space for data buffer at scanline %ld: — this means TIFFReadBufferSetup() was unable to dynamically allocate space for a data buffer. she tried, she really did 😭
• %s: No space for output buffer: — this means TIFFWriteBufferSetup() was unable to dynamically allocate space for a data buffer. rough out here fr fr.

lowkey if you made it this far you're officially a buffering bestie 🎀
