TIFFCODEC(3tiff)

💖 TIFFCODEC 💖

okay bestie, pull up a chair, we're doing TIFFCODEC(3tiff) from the LibTIFF fam — codec-related utility routines, aka the little functions that handle who-does-what when your TIFF gets squished. let's go 💅

✨ NAME ✨

TIFFcodec — codec-related utility routines 🎀

---

🌸 SYNOPSIS 🌸

#include <tiffio.h>

const TIFFCodec *TIFFFindCODEC(uint16_t scheme)

TIFFCodec *TIFFRegisterCODEC(uint16_t scheme, const char *method,
TIFFInitMethod init)

void TIFFUnRegisterCODEC(TIFFCodec *codec)

int TIFFIsCODECConfigured(uint16_t scheme)

TIFFCodec *TIFFGetConfiguredCODECs(uint16_t scheme)

int TIFFSetCompressionScheme(TIFF *tif, int scheme)

---

🦋 DESCRIPTION 🦋

so libtiff supports a whole buffet of compression schemes, and every single one of them is implemented by a software codec. each codec follows the same modular interface, and that interface is doing a LOT — it handles decoding and encoding of image data, plus some other methods for initialization, setup, cleanup, and controlling the default strip and tile sizes. ✨

codecs get identified by the value of the associated TIFF Compression tag — like 5 for LZW compression. iykyk 🫶

TIFFFindCODEC() ??????

TIFFUnRegisterCODEC() ??????

TIFFRegisterCODEC() is your main character here — it can augment or override the set of codecs available to an application. and listen: if the scheme you specified already has a registered codec, then it gets overridden, and any images with data encoded with that compression scheme will be decoded using the supplied codec instead. no cap, that's the deal. 👑

TIFFIsCODECConfigured() returns 1 if the codec is configured and working. otherwise 0 will be returned. that's it, that's the vibe check. ⭐

TIFFGetConfiguredCODECs() gets you the list of configured codecs — both the built-in ones and the ones registered by the user. the function returns an array of TIFFCodec records (and the last record should be NULL), or NULL if the function failed. 🙈 and heads up bestie: the caller is responsible to free this structure. that's on you, not us. 💀

TIFFSetCompressionScheme() ????

🌈 DIAGNOSTICS 🌈

• No space to register compression scheme %s — TIFFRegisterCODEC() was unable to allocate memory for the data structures needed to register a codec. 😭 it's giving out-of-memory, not giving slay.
• Cannot remove compression scheme %s; not registered — TIFFUnRegisterCODEC() did not locate the specified codec in the table of registered compression schemes. so it literally cannot remove what was never there, bestie.
