Apply conditions to dynamically manipulate images.

It's great to have the capability to manipulate images on the fly by using dynamic URLs to customize the images to fit the graphic design of your site or mobile application. However, what if you want to manipulate an image depending on a specific image characteristic (like its width or aspect ratio) or its contents (does it contain a face?). What you need is a way to apply a transformation to an image only if a specific condition is met. Take for example a situation where you have allocated space on your page for a user uploaded image with a width and height of 200 pixels. Furthermore, if the image contains a face you would like to zoom in and focus on the face itself, otherwise you would like to fit the entire image into the available space:

Powerful facial detection for image manipulation

Many of the photos displayed on the internet these days are of people. If your website or mobile application displays photos that include people, you will want to make sure that their faces are included in the delivered images when cropping and manipulating them to fit your graphic design and responsive layout. You may even want to further manipulate an image according to the faces present, for example, adding a harlequin mask overlay on all of their eyes, where each mask is adjusted to the correct size and orientation (although not a typical use case, it's a cool example of using advanced facial attribute detection):

Using error reports to identify image delivery issues

If you have a web site or mobile application, chances are you need to deliver a lot of media resources, especially images, to your users. How would you know if all your images were delivered correctly to your users and if there were no broken images displayed on your website? Maybe you build image URLs based on a certain naming convention and you end up with URLs that point to non-existing images, which result in HTTP status errors and broken images? Maybe search engines like Google have indexed the URLs of your images that were subsequently deleted or modified, and these URLs now generate errors when accessed?

Introducing responsive image breakpoints solutions

The number of different devices available and their potential screen resolutions keep increasing, and to support this wide range of resolutions and devices, responsive website design is now the standard. A website's markup must adapt itself to look perfect on all the different devices and in various resolutions, pixel densities and mobile device orientations. Managing, manipulating and delivering images, is one of the main challenges of responsive design that web developers face.

Happy New Year and a hat trick

As the end of 2015 approaches, we wanted to share a quick summary of Cloudinary’s accomplishment this year and some of our plans for next year. We couldn't possibly do this without including an image manipulation example! That's our hat trick in the title :-)

Dynamically distort images to fit your graphic design

It can be quite a challenge to graphically design a website or mobile application that displays images in very precise shapes and orientations. This can take the form of warping 2D pictures to have a 3D perspective, placing images in precise shapes or overlaying images in specific locations within another image, for example: overlaying an image over the screen of a smartphone.

Build A/B Testing & Personalization creative on the fly

Content Optimization and Personalization programs can deliver tremendous ROI to an organization but tend to be very resource intensive, requiring developers to build the code for alternate experiences and creative folks to generate the content. Many of the content optimization/personalization tools out there today (Maxymiser, Optimizely, Adobe Target, Ensighten etc.) have created WYSIWYG (What You See Is What You Get) editors to help relieve the code/development bottleneck but the creative bottleneck stubbornly remains.
