imagemagick-darwin-static

imagemagick static binaries for Mac OSX x64

When you want to write text into images, you have to pass the font explicitly.

Important

you have to set the an environment variable to use it via spawn or cli.

// like you do in the bash:
export MAGICK_HOME= "path/to/node_modules/imagemagick-darwin-static/bin/osx/imagemagick/7.0.5-5/"
export DYLD_LIBRARY_PATH= "path/to/node_modules/imagemagick-darwin-static/bin/osx/imagemagick/7.0.5-5/lib/"
 
 
// with spawn, this can be done via the options parameter:
// child_process.spawn(command[, args][, options])
 
var convert_binary= "path/to/node_modules/imagemagick-darwin-static/bin/osx/imagemagick/7.0.5-5/bin/convert"
var MAGICK_HOME= "path/to/node_modules/imagemagick-darwin-static/bin/osx/imagemagick/7.0.5-5/"
var DYLD_LIBRARY_PATH= "path/to/node_modules/imagemagick-darwin-static/bin/osx/imagemagick/7.0.5-5/lib/"
 
var spawn = require("child_process").spawn;
 
 
 
var proc = spawn(convert_binary,
                ['/path/to/infille.jpg', '/path/to/outfile.png'],
                 {
                    MAGICK_HOME: MAGICK_HOME,
                    DYLD_LIBRARY_PATH: DYLD_LIBRARY_PATH
                  }
);

This is, because the dynamic libs are located in the lib folder inside this package. And imagemagick needs to know about this.

Motivation

Use imagemagick in electron.atom applications for mac For more information about electron atom see https://electron.atom.io/

Installation

This module is installed via npm:

$ npm install imagemagick-darwin-static

Example Usage

Returns the path of a statically linked graphicsmagick on the local filesystem.

var imagemagick = require('imagemagick-darwin-static');
console.log(imagemagick.path);
 

For Windows (32 and 64-bit) please use graphicsmagic-static.

Best usage is with npm module gm

var os = require("os");
var graphicsmagick = require("graphicsmagick-static");
var imagemagick = require("imagemagick-darwin-static");
var imageHandler = null;
 
if (os.platform() == "win32") {
    gm = require("gm").subClass({
        appPath: path.join(graphicsmagick.path, "/")
    })
} else {
 
    gm = require("gm").subClass({
        imageMagick: true,
        appPath: path.join(imagemagick, "/")
    })
}
 
// then do any stuff you need
 
gm("/path/to/image.png").resize(150,150).write("/new/path.jpg", (err) => {
    
    // here an example
    if (err) return callback(err, null);
});

Electron and Asar

Thinks to keep in mind when packing electron apps with ASAR. Using e.g. the electron-builder, this package and as well graphicsmagick-static should be placed in the app.asar.unpacked folder. Electron builder does this automatically, because of the big binaries.

How ever, when done so, you will have to replace the path of the app.asar to app.asar.unpacked.

This could be achieved by a helper class as given:

import path from 'path';
 
export default class AppPaths {
    static replaceAsar(path = "") {
        return path.replace(".asar", ".asar.unpacked");
    }
}
 
...
 
// Usage:
 
import AppPaths from 'WhatYouCalledTheFile';
var imagemagickPath = require("imagemagick-darwin-static").path;
let fixedPath = AppPaths.replaceAsar(imagemagickPath);
 
// Example for using ASAR:
 
var os = require("os");
var graphicsmagick = require("graphicsmagick-static");
var imagemagick = require("imagemagick-darwin-static");
var imageHandler = null;
 
if (os.platform() == "win32") {
    gm = require("gm").subClass({
        appPath: AppPaths.replaceAsar(path.join(graphicsmagick.path, "/"))
    })
} else {
 
    gm = require("gm").subClass({
        imageMagick: true,
        appPath: AppPaths.replaceAsar(path.join(imagemagick.path, "/"))
    })
}
 
// then do any stuff you need
 
gm("/path/to/image.png").resize(150,150).write("/new/path.jpg", (err) => {
    
    // here an example
    if (err) return callback(err, null);
});
