💖 identify-im7.q16(1) — the manual page, but make it make sense 💖

okay bestie, listen up — this is the manual page for identify-im7.q16(1), which lives under General Commands Manual. It's part of the ImageMagick family and it's basically the friend who looks at your pics and tells you everything about them. No cap.

✨ NAME ✨

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

🦋 SYNOPSIS 🦋

magick-im7.q16 identify [options] input-file

🌸 OVERVIEW 🌸

So identify-im7.q16 is a member of the ImageMagick-ims7.q16(1) suite of tools (yes, the whole girl group). What does it do? It describes the format and characteristics of one or more image files, and it will also clock an image that's incomplete or corrupt. Not it being a detective. 🕵️♀️

Here's the tea it hands 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 (this is off by default — turn it on with the -define unique=true option)
  • 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 if that's not enough for you, many more attributes are available with the verbose option. She contains multitudes. 👑

  • -depth value — image depth
  • -endian type — endianness (MSB or LSB) of the image
  • -extract geometry — extract area from image
  • -features distance — analyze image features (e.g. contrast, correlation)
  • -format "string" — output formatted image characteristics
  • -fuzz distance — colors within this distance are considered equal
  • -gamma value — of gamma correction
  • -interlace type — type of image interlacing scheme
  • -interpolate method — pixel color interpolation method

  • -moments — report image moments
  • -monitor — monitor progress
  • -ping — efficiently determine image attributes

  • -quiet — suppress all warning messages (shhh 🤫)
  • -read-mask filename — associate a read mask with the image
  • -regard-warnings — pay attention to warning messages
  • -respect-parentheses — settings remain in effect until parenthesis boundary
  • -sampling-factor geometry — horizontal and vertical sampling factor
  • -seed value — seed a new sequence of pseudo-random numbers
  • -set attribute value — set an image attribute
  • -size geometry — width and height of image
  • -strip — strip image of all profiles and comments
  • -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
  • -channel mask — set the image channel mask
  • -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 and here's a lil formatting moment you need to know: 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 you can specify file as - for standard input or output. Iconic behaviour, honestly. 💫

⚠️ NOTE ⚠️

Real talk, bestie. Even though some options look like they're modifying the file you're identifying — they are NOT. The identify command is strictly read only. For instance, the crop option crops the in-memory image and then describes the result. Your file is safe. She's just looking. 👀
