Javascript is a programming language for the web. We can use to create very useful things such as libraries, that users can easily use the benefits of this programming language with less code. Today i will show you javascript library for fast joining photos, useful for creating featured images or banners for web sites like gsmarena.com where users can compare two or more mobile phones.
Photojoiner is a javascript lightweight library (880 B) for joining photos. You can use this library without jQuery.
Basic usage
Load photojoiner.js or photojoiner.min.js in the end of the document ( to stop render blocking )
<script type="text/javascript" src="photojoiner.js"></script>
<script>
// Array of images, static or dynamically added with .push() method
images = ['http://b-i.forbesimg.com/larrymagid/files/2013/04/galaxy1.jpg',
'https://www.trylumiaphone.com/images/home/phone2.png'];
// Send images array as a parameter, required
photojoiner.join({
'images' : images
});
</script>
Advanced usage
Except required parameter images, you can pass more parameters to adjust photojoiner
images
Array of urls. This parameter is required
photojoiner.join({
'images' : ['image1.jpg','image2.jpg','image3.jpg']
});
canvasHeight
Integer value for height of the container. Default value is 350 that means, the output image will be with height of 350px and pictures will bi scaled to the height
photojoiner.join({
'images' : ['image1.jpg','image2.jpg','image3.jpg'],
'canvasHeight': 500
});
canvas
HTML dom node. Default is canvas element with id joined. You can send your own canvas element
photojoiner.join({
'images' : ['image1.jpg','image2.jpg','image3.jpg'],
'canvas':document.getElementById('my_canvas_element')
});
How many pictures can i join?
You can join unlimited number of pictures. Send urls of the pictures as a parameter, and photojoiner will join all pictures.
Example output with more than two pictures
images = ['http://cdn2.gsmarena.com/vv/bigpic/xolo-black-2015.jpg','http://cdn2.gsmarena.com/vv/bigpic/xiaomi-mi4i.jpg','http://cdn2.gsmarena.com/vv/bigpic/samsung-galaxy-grand-prime-sm-g530h.jpg','http://cdn2.gsmarena.com/vv/bigpic/apple-iphone-5c-new1.jpg','http://cdn2.gsmarena.com/vv/bigpic/apple-iphone-6-3.jpg'];
photojoiner.join({

});
