How to pad images with automatic color selection

Auto padding images with content-aware color padding

How you present the content of your website can be just as important as the content itself. The images you display need to conform to the graphic design of your site, and every image needs to fit within a predefined size. Although that may be simple enough to achieve when you are dealing with your own images, the task can be more challenging when displaying images uploaded by your users.

Your users could potentially upload their images in a variety of resolutions and sizes. This means you need to adjust the images on-the-fly to fit within the available space defined by your graphic design. However, for images that are uploaded with a different aspect ratio than the area reserved to display it, a simple scaled resize will result in extra space either above and below the image or on the left and right. It also could affect the spacing of other elements on your page. To make sure you end up with an image that is the right size to fill all of the available space, you will generally need to add padding to the image as well, either using CSS or by manipulating the original image.

Simple image padding

Now the question becomes, how do you add the extra padding to the image so that the end result fits properly and looks professional? We could simply decide that the extra padding added to all the images needs to conform to a specific color, for example: white. You could use CSS for this purpose, but Cloudinary makes this process much easier to accomplish. Cloudinary offers a comprehensive end-to-end solution for all elements of image and media management, enabling web and app developers to invest their full focus on the main purpose of their own site, or app. To add padding in a specific color with Cloudinary, you use one of the padding crop modes together with the background parameter set to the color you want. For example, padding the bottle image with white so that it fits within a height and width of 300 pixels, along with with a black border:

Ruby:
Copy to clipboard
cl_image_tag("bottle.jpg", :transformation=>[
  {:width=>300, :height=>300, :background=>"white", :crop=>"pad"},
  {:border=>"2px_solid_black"}
  ])
PHP:
Copy to clipboard
cl_image_tag("bottle.jpg", array("transformation"=>array(
  array("width"=>300, "height"=>300, "background"=>"white", "crop"=>"pad"),
  array("border"=>"2px_solid_black")
  )))
Python:
Copy to clipboard
CloudinaryImage("bottle.jpg").image(transformation=[
  {'width': 300, 'height': 300, 'background': "white", 'crop': "pad"},
  {'border': "2px_solid_black"}
  ])
Node.js:
Copy to clipboard
cloudinary.image("bottle.jpg", {transformation: [
  {width: 300, height: 300, background: "white", crop: "pad"},
  {border: "2px_solid_black"}
  ]})
Java:

cloudinary.url().transformation(new Transformation()
  .width(300).height(300).background("white").crop("pad").chain()
  .border("2px_solid_black")).imageTag("bottle.jpg");

How to Optimize for Page Load Speed

Automatic color padding

Setting a uniform color for all padding might be a good solution for some of your images, but what if you could automatically set the padding color based on the color of the border pixels in the image? Any padding added would then have the effect of extending the image canvas, and make it appear as if the padded region is actually part of the image itself. Guess what? Cloudinary makes this simple too. All you have to do is set the background parameter to auto (b_auto in URLs). For example, here's the same bottle image as above, but now with automatic color padding:

Ruby:
Copy to clipboard
cl_image_tag("bottle.jpg", :transformation=>[
  {:width=>300, :height=>300, :background=>"auto", :crop=>"pad"},
  {:border=>"2px_solid_black"}
  ])
PHP:
Copy to clipboard
cl_image_tag("bottle.jpg", array("transformation"=>array(
  array("width"=>300, "height"=>300, "background"=>"auto", "crop"=>"pad"),
  array("border"=>"2px_solid_black")
  )))
Python:
Copy to clipboard
CloudinaryImage("bottle.jpg").image(transformation=[
  {'width': 300, 'height': 300, 'background': "auto", 'crop': "pad"},
  {'border': "2px_solid_black"}
  ])
Node.js:
Copy to clipboard
cloudinary.image("bottle.jpg", {transformation: [
  {width: 300, height: 300, background: "auto", crop: "pad"},
  {border: "2px_solid_black"}
  ]})
Java:
Copy to clipboard
cloudinary.url().transformation(new Transformation()
  .width(300).height(300).background("auto").crop("pad").chain()
  .border("2px_solid_black")).imageTag("bottle.jpg");
JS:
Copy to clipboard
cloudinary.imageTag('bottle.jpg', {transformation: [

Automatically selecting the padding color is a great solution for images with a solid background color, but it also gives good results on images without a solid background color. For example, take a look at this dog image with automatic color padding:

Ruby:
Copy to clipboard
cl_image_tag("dog.jpg", :width=>300, :height=>300, :background=>"auto", :crop=>"pad")
PHP:
Copy to clipboard
cl_image_tag("dog.jpg", array("width"=>300, "height"=>300, "background"=>"auto", "crop"=>"pad"))
Python:
Copy to clipboard
CloudinaryImage("dog.jpg").image(width=300, height=300, background="auto", crop="pad")
Node.js:
Copy to clipboard
cloudinary.image("dog.jpg", {width: 300, height: 300, background: "auto", crop: "pad"})
Java:
Copy to clipboard
cloudinary.url().transformation(new Transformation().width(300).height(300).background("auto").crop("pad")).imageTag("dog.jpg");
JS:
Copy to clipboard
cloudinary.imageTag('dog.jpg', {width: 300, height: 300, background: "auto", crop: "pad"}).toHtml();
jQuery:
Copy to clipboard
$.cloudinary.image("dog.jpg", {width: 300, height: 300, background: "auto", crop: "pad"})
React:
Copy to clipboard
<Image publicId="dog.jpg" >
  <Transformation width="300" height="300" background="auto" crop="pad" />
</Image>
Vue.js:

<cld-image publicId="dog.jpg" >
  <cld-transformation width="300" height="300" background="auto" crop="pad" />

  <cl-transformation width="300" height="300" background="auto" crop="pad">
  </cl-transformation>
</cl-image>
.Net:
Copy to clipboard
cloudinary.Api.UrlImgUp.Transform(new Transformation().Width(300).Height(300).Background("auto").Crop("pad")).BuildImageTag("dog.jpg")
Android:
Copy to clipboard
MediaManager.get().url().transformation(new Transformation().width(300).height(300).background("auto").crop("pad")).generate("dog.jpg");

Image with a spectrum of background colors and automatic color padding

Fade the image into the padding

We can see in the example above that the predominant color has been calculated to be a particular shade of green, resulting in a visually pleasing padded image. The jump between the image and the border may feel somewhat stark, but we can fade the picture into the padding by applying the gradient_fade effect with a value of symmetric_pad (e_gradient_fade:symmetric_pad in URLs). For example, the same dog image as above, but now with the image faded into the padding:

Ruby:
Copy to clipboard
cl_image_tag("dog.jpg", :width=>300, :height=>300, :background=>"auto", :effect=>"gradient_fade:symmetric_pad", :crop=>"pad")
PHP:
Copy to clipboard
cl_image_tag("dog.jpg", array("width"=>300, "height"=>300, "background"=>"auto", "effect"=>"gradient_fade:symmetric_pad", "crop"=>"pad"))
Python:
Copy to clipboard
CloudinaryImage("dog.jpg").image(width=300, height=300, background="auto", effect="gradient_fade:symmetric_pad", crop="pad")
Node.js:
Copy to clipboard
cloudinary.image("dog.jpg", {width: 300, height: 300, background: "auto", effect: "gradient_fade:symmetric_pad", crop: "pad"})
Java:
Copy to clipboard
cloudinary.url().transformation(new Transformation().width(300).height(300).background("auto").effect("gradient_fade:symmetric_pad").crop("pad")).imageTag("dog.jpg");
JS:
Copy to clipboard
cloudinary.imageTag('dog.jpg', {width: 300, height: 300, background: "auto", effect: "gradient_fade:symmetric_pad", crop: "pad"}).toHtml();
jQuery:
Copy to clipboard
$.cloudinary.image("dog.jpg", {width: 300, height: 300, background: "auto", effect: "gradient_fade:symmetric_pad", crop: "pad"})
React:
Copy to clipboard
<Image publicId="dog.jpg" >
  <Transformation width="300" height="300" background="auto" effect="gradient_fade:symmetric_pad" crop="pad" />
</Image>
Vue.js:
Copy to clipboard
<cld-image publicId="dog.jpg" >
  <cld-transformation width="300" height="300" background="auto" effect="gradient_fade:symmetric_pad" crop="pad" />

<cl-image public-id="dog.jpg" >
  <cl-transformation width="300" height="300" background="auto" effect="gradient_fade:symmetric_pad" crop="pad">

Image with a gradient fade into automatic color padding

You can also control how much of the image to include in the fading effect by adding the x parameter with a value that indicates the width of the fading region in pixels. For example, the same dog image as above, but now with only a 50 pixel wide gradient fade into the padding:

Ruby:
Copy to clipboard
cl_image_tag("dog.jpg", :width=>300, :height=>300, :background=>"auto", :effect=>"gradient_fade:symmetric_pad", :x=>50, :crop=>"pad")
PHP:
Copy to clipboard
cl_image_tag("dog.jpg", array("width"=>300, "height"=>300, "background"=>"auto", "effect"=>"gradient_fade:symmetric_pad", "x"=>50, "crop"=>"pad"))
Python:
Copy to clipboard
CloudinaryImage("dog.jpg").image(width=300, height=300, background="auto", effect="gradient_fade:symmetric_pad", x=50, crop="pad")
Node.js:
Copy to clipboard
cloudinary.image("dog.jpg", {width: 300, height: 300, background: "auto", effect: "gradient_fade:symmetric_pad", x: 50, crop: "pad"})
Java:
Copy to clipboard
cloudinary.url().transformation(new Transformation().width(300).height(300).background("auto").effect("gradient_fade:symmetric_pad").x(50).crop("pad")).imageTag("dog.jpg");

More padding options

The examples in this article are some of the most frequent uses of padding options, but you can fine tune the way padding is added in a number of other ways. The following examples give a taste of what can be accomplished by tweaking the value of the b_auto parameter:

  • Select the predominant color of the entire image or only the border pixels:
b_auto:border b_auto:border b_auto:predominant b_auto:predominant
