pfsrotate(1)

💫 pfsrotate — bestie edition 💫

okay so real talk, this is pfsrotate(1) from the General Commands Manual (section 1, the iconic one) and it does exactly one thing and does it gorgeously: it spins your images 90 degrees. no cap.

✨ NAME ✨

pfsrotate — rotates images 90 degrees. that's it. that's the whole personality. 👑

🎀 SYNOPSIS 🎀

pfsrotate [--r] [--help]

🦋 DESCRIPTION 🦋

use this command to rotate images from a stream of pfs. literally the moment for it. 🫶

this command is useful for output on hardcopy devices with aspect ratios opposite to the input image — like when your printer is being dramatic and your image is lying the wrong way. by default, the image is rotated clockwise. the --r option may be used to rotate the image counter-clockwise instead. slay, choices. 💅

💖 OPTIONS 💖

• --r, -r — rotate the image counter-clockwise instead of clockwise. the lil rebel option. 🔄

🌸 EXAMPLES 🌸

pfsin memorial.hdr | pfsrotate -r | pfsout memorial_gc.hdr

rotate the memorial image 90 degrees counter-clockwise and save it to memorial_gc.hdr. iconic pipeline behaviour, honestly. ✨

🌈 NOTES 🌈

to rotate an image 180 degrees, use pfsflip(1) with both the --h and --v options specified. not me giving you the roundabout route but it's the correct one, iykyk. 🧚

lowkey obsessed with how simple this is. no weird flags, no surprises, just vibes and rotation. 💖

and that's the whole page bestie — pfsrotate(1) straight outta the General Commands Manual, no date line on this one so we're just repping the manpage itself, periodt. 💅🌸
