An Elixir wrapper for ImageMagick command line.

Documentation: https://hexdocs.pm/mogrify/

Requirements

You must have ImageMagick installed of course.

Installation

Add this to your mix.exs file, then run mix do deps.get, deps.compile:

def deps do
  {:mogrify, "~> 0.8.0"}
end

Configuration

Configure the ImageMagick executable paths (optional):

Configure mogrify command:

config :mogrify, mogrify_command: [
  path: "mogrify",
  args: []
]

Configure convert command:

config :mogrify, convert_command: [
  path: "convert",
  args: []
]

Examples

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") |> save

Converting:

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}

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.
