An Elixir wrapper for ImageMagick command line.
Documentation: https://hexdocs.pm/mogrify/
You must have ImageMagick installed of course.
Add this to your mix.exs file, then run mix do deps.get, deps.compile:
def deps do
{:mogrify, "~> 0.9.3"}
endConfigure the ImageMagick executable paths (optional):
Configure mogrify command:
config :mogrify, mogrify_command: [
path: "magick",
args: ["mogrify"]
]Configure convert command:
config :mogrify, convert_command: [
path: "magick",
args: ["convert"]
]Configure identify command:
config :mogrify, identify_command: [
path: "magick",
args: ["identify"]
]Thumbnailing:
import Mogrify
# This does operations on an original image:
open("input.jpg") |> resize("100x100") |> save(in_place: true)
# save/1 creates a copy of the file by default:
image = open("input.jpg") |> resize("100x100") |> save
IO.inspect(image) # => %Image{path: "/tmp/260199-input.jpg", ext: ".jpg", ...}
# Resize to fill
open("input.jpg") |> resize_to_fill("450x300") |> save
# Resize to limit
open("input.jpg") |> resize_to_limit("200x200") |> save
# Extent
open("input.jpg") |> extent("500x500") |> save
# Gravity
open("input.jpg") |> gravity("Center") |> saveConverting:
import Mogrify
image = open("input.jpg") |> format("png") |> save
IO.inspect(image) # => %Image{path: "/tmp/568550-input.png", ext: ".png", format: "png"}Getting info:
import Mogrify
image = open("input.jpg") |> verbose
IO.inspect(image) # => %Image{path: "input.jpg", ext: ".jpg", format: "jpeg", height: 292, width: 300}Getting reduced info in a "lighter" way (uses less memory):
import Mogrify
info = identify("input.jpg")
IO.inspect(info) # => %{format: "jpeg", height: 292, width: 300}Using custom commands to create an image with markup:
import Mogrify
%Mogrify.Image{path: "test.png", ext: "png"}
|> custom("size", "280x280")
|> custom("background", "#000000")
|> custom("gravity", "center")
|> custom("fill", "white")
|> custom("font", "DejaVu-Sans-Mono-Bold")
|> custom("pango", ~S(<span foreground="yellow">hello markup world</span>))
|> create(path: ".")Plasma backgrounds:
import Mogrify
%Mogrify.Image{path: "test.png", ext: "png"}
|> custom("size", "280x280")
|> custom("seed", 10)
|> custom("plasma", "fractal")Creating new images: See mogrify_draw for an example of generating a new image from scratch.
