πŸ’– TIFFFIELDPASSCOUNT πŸ’–

okay bestie, welcome to the TIFFFIELDPASSCOUNT(3tiff) page, part of the LibTIFF fam πŸ’… this one's a lil three-arg mystery solver, and honestly? she's lowkey iconic for it.


✨ NAME ✨

TIFFFieldPassCount β€” get whether to pass a count to TIFFGetField/TIFFSetField

like... does this field want a lil number handed to it first, or not?? that's literally the whole job 🫢


🌸 SYNOPSIS 🌸

#include <tiffio.h>

int TIFFFieldPassCount(const TIFFField *fip)

πŸ¦‹ DESCRIPTION πŸ¦‹

TIFFFieldPassCount() returns true (nonzero) if TIFFGetField() and TIFFSetField() expect a count value to be passed before the actual data pointer.

read that again bestie. the count comes first. the data comes after. order matters, no cap 😭

fip is a field information pointer previously returned by TIFFFindField(), TIFFFieldWithTag(), TIFFFieldWithName().

so like, you don't just make one up out of thin air β€” you gotta get it from one of those three cuties first ✨

When a count is required, it will be of type uint32_t if TIFFFieldReadCount() reports TIFF_VARIABLE2, and of type uint16_t otherwise. Use TIFFFieldWriteCount() for TIFFSetField(), respectively. (This distinction is critical for use of TIFFGetField(), but normally not so for use of TIFFSetField().)

⚠️ okay the uint32_t vs uint16_t thing is not a vibe, it's a whole personality. get it wrong on TIFFGetField() and things get real bad real fast πŸ’€ but for TIFFSetField()? normally it's chill, don't stress it.

An alternative function for the count value determination is TIFFFieldSetGetCountSize().

(not me giving you options, we love a backup plan πŸ’œ)


🌈 RETURN VALUES 🌈

TIFFFieldPassCount() returns an integer that is always 1 (true) or 0 (false).

that's it. binary. no in-between. no "maybe". it's giving main character energy and it's giving decisive πŸ‘‘
