💖 mogrify(1) 💖

hey bestie! welcome to the mogrify(1) page from the General Commands Manual. this is part 1, so buckle up 🎀

✨ NAME ✨

okay so mogrify is literally that girl 💅 she resizes, blurs, crops, despeckles, dithers, draws on, flips, joins, re-samples, and does so much more. but here's the tea ☕: she overwrites the original image file, no cap. whereas convert(1) writes to a different image file. periodt.

🌸 SYNOPSIS 🌸

magick mogrify [options] input-file

🦋 OVERVIEW 🦋

mogrify is part of the ImageMagick(1) squad, bestie 🫶. you use it to resize, blur, crop, despeckle, dither, draw on, flip, join, re-sample, and much more ✨. it's basically convert(1)'s twin, except the original image file gets overwritten with any changes you ask for. so like, be careful, okay? 🙈

  • -insert index — insert last image into the image sequence

  • -log format — format of debugging information
  • -list type — print a list of supported option arguments
  • -version — print version information

okay so here's a lil thing you need to know, and it's giving very important 🫶

by default, the image format of file is figured out from its magic number (yes, real term, iconic name, no notes). but if you wanna be specific and lock in a particular format, you've got two moves:

  1. put an image format name and a colon before the filename — like ps:image
  2. or just name the file so the format is the suffix — like image.ps

and if you want standard input or standard output? put - as the file. that's it, that's the whole trick 💖
