💖 pfsintiff 💖

okay so bestie, welcome to pfsintiff, from the General Commands Manual (section 1, we're fancy). this is the little tool that scoops up your TIFF files and yeets them into a pfs stream. let's get into it 🎀

✨ NAME ✨

pfsintiff — load images or frames in several variants of TIFF format (both LDR and HDR) 🦋

✨ SYNOPSIS ✨

pfsintiff (<file> [--linear] [--frames <range>] [--skip-missing])
[<file>...]

✨ DESCRIPTION ✨

okay so the whole vibe: pfsintiff loads images in TIFF format and writes a pfs stream to the Standard Output. that stream is usually piped straight into another program for further processing, it's giving relay race 🏃♀️. and if you want the format detected automatically based on the extension instead? use pfsin, she's the one who guesses 🫶

it handles both the standard LDR tiff and the extended HDR (logLuv encoding, literally here: http://www.anyhere.com/gward/pixformat/tiffluv.html). and no cap, both LDR and HDR tiff files provide photometric data (i.e. linearly related to luminance). the 'LUMINANCE' tag is set to 'RELATIVE', and also the --linear switch is ignored. periodt 💅

want to read images from standard input? use a single dash - instead of a filename. images get read until EOF is reached, that's it, that's the whole story 🌸

every file can contain a %d pattern, which gets substituted with frame numbers. the pattern has the same syntax as the C printf command. for example, you can use %04d to make the frame number four digit with proceedings zeros. iconic. you can select the frames using the following options — and bestie, listen, the options must be always given after the file name ⚠️

🌈 OPTIONS 🌈

• --frames <range> — the range is given in mathlab / octave format:

startframe:step:endframe

frame numbers start with startframe (default 0), are increased by step (default 1) and stop at endframe. you can skip one of those values, for example 1:100 for frames 1,2,...,100 and 0:2: for frame 0,2,4,... up to the last file that exists. so flexible, we love a range 💜

• --skip-missing — skip up to ten frames in a row if the corresponding files are missing. otherwise the program stops reading the sequence at the first file that does not exist. heads up: this switch does not apply to the first frame in a sequence. this switch can be useful if there is a rendered animation where some of the frames have not been generated 🙈 (we've all been there, half-rendered, no notes)
• --linear — ignored, for compatibility with pfsinppm. she's just here to vibe, doing nothing, living her truth ✨

✨ EXAMPLES ✨

pfsintiff frame%04d.tif --frames 0:10 | pfsview

read frames from files frame0000.tif, frame0001.tif, ..., frame0010.tif and show them using pfsview. chef's kiss 👑
