💖 identify-im6.q16(1) — General Commands Manual 💖

okay so bestie, pull up a chair, we're reading a man page together and honestly? it's a good one. this is identify-im6.q16, straight out of the General Commands Manual, and it's about to tell you literally everything about your image files. 🫶

✨ NAME ✨

identify — describes the format and characteristics of one or more image files. that's it, that's the job, and it eats every time. 💅

🌸 SYNOPSIS 🌸

identify-im6.q16 [options] input-file

🦋 OVERVIEW 🦋

so identify-im6.q16 is a member of the ImageMagick-ims6.q16(1) suite of tools, iykyk. it describes the format and characteristics of one or more image files. and like, it also reports if an image is incomplete or corrupt — which is honestly such a mood, we love a program that tells the truth. 💀

here's the tea on what it hands back to you:

  • the image number
  • the file name
  • the width and height of the image
  • whether the image is colormapped or not
  • the number of colors in the image — and heads up, by default this is off, so use the -define unique=true option if you want it
  • the number of bytes in the image
  • the format of the image (JPEG, PNM, etc.)
  • and finally, the number of seconds it took to read and process the image

and there's many more attributes available with the verbose option. the way that -verbose just unlocks a whole new world? iconic. 👑

  • -unique — display the number of unique colors in the image
  • -units type — the units of image resolution
  • -verbose — print detailed information about the image
  • -virtual-pixel method — virtual pixel access method

🧚 Image Operators 🧚

  • -auto-orient — automatically orient image
  • -grayscale method — convert image to grayscale
  • -negate — replace each pixel with its complementary color

🍓 Miscellaneous Options 🍓

  • -debug events — display copious debugging information
  • -help — print program options
  • -list type — print a list of supported option arguments
  • -log format — format of debugging information
  • -version — print version information

okay now the important bit, bestie. 💖

by default, the image format of file is determined by its magic number. to specify a particular image format, precede the filename with an image format name and a colon (i.e. ps:image) or specify the image type as the filename suffix (i.e. image.ps). and specify 'file' as '-' for standard input or output. slay. ✨

🙈 NOTE 🙈

so this is the part where it gets a lil spooky but it's fine, i promise. even though some options appear to modify the file to be identified, the identify command is strictly read only. like, for instance, the crop option crops the in-memory image and then describes the result. your file on disk? untouched. untouched, bestie. no cap. 💅
