A few simple tests with node-imagemagic
node-imagemagic identify method works fine by its self.
var im = require('imagemagick');
var assert = require('assert');
console.log("Current Directory: "+__dirname);
var parentDir = __dirname.substring(0, __dirname.lastIndexOf('/'));
console.log("Parent Directory: " + parentDir);
var filename = parentDir+'/sample-images/kittens.jpg';
im.identify(filename, function(err, ia) { // ia = image attibutes
console.log("Filename: " + filename);
assert.equal(ia.width, 1600);
assert.equal(ia.height, 1200);
});If you download this repo and run npm install followed by:
istanbul cover lib you will see 100% coverage
(i.e. we are executing im.identify successfully):
However when I try to wrap im.identify in a method (with a callback) it fails:
var IR = {}
/* * Trying to Wrap the im.identify in a function with callback * */
IR.getOriginalImageAttributes = function(filename, callback) {
return im.identify(filename, function(err, ia) {
console.log("Filename: " + filename);
console.log(ia);
callback(ia); // do something with the image attributes
});
};
/* * * * */
module.exports = IR;
