### Dynamic Asset Transformations (DAT)

Would you like to generate customized derivatives on demand and use them in your external systems? With Dynamic Asset Transformations (DAT) you can request a customized derivative by adding parameters to DAT derivative URL.

By using Dynamic Asset Transformations that are optimized for the platform and/or device your users are working on you can ensure that they have the best user experience possible.

When creating Dynamic Asset Transformations the system uses the focus point that has been set on an asset level. If needed, you can change this focus point by using parameters. The DAT service also automatically invalidates the Bynder CDN cache when a new manual focus point is set in the Asset Detail view or when a new asset version is uploaded. This ensures that the image will be updated everywhere the Bynder CDN reference is used, which ensures consistency across your brand.

Dynamic Asset Transformations are fully integrated into your Bynder Dam making sure you don't need to rely on external systems for derivative generation. Find out below how you can start integrating Dynamic Asset Transformations into your external websites, social media platforms and email newsletters.

#### How to Use Dynamic Asset Transformations?

Dynamic Asset Transformation give you the freedom to generate the derivative you want on the fly. One of the best practices to implement DAT is to use the srcset attribute. With this attribute you can define different size variations of the same image and provide information about the size of each one. The browser of your end users will then decide which image variation to display based on the end users' screen size. Read more about responsive image sizing here.

Are you not sure if Dynamic Asset Transformations are what you're looking for and would you like to try it first?

Below you'll find some example base URLs that you can customize using the available parameters. Check out this section for more information on how you can apply those parameters. A preview of the original images can be found in the table below.

For example the following URL will create a crop of 1200x1200 pixels of the Musician photo and the focal point will be automatically detected.

Inform your Customer Success Manager that you would like to participate in the Beta program. Your Customer Success Manager will be happy to further assist you in setting this up.

#### How to Create Dynamic Asset Transformations?

You can create Dynamic Asset Transformations by adding parameters to the DAT derivative URL.

1. Open the asset for which you want to create a Dynamic Asset Transformation.

2. Copy the DAT derivative URL in the Link to public files section. This URL functions as the base URL to which you'll add your transformations.

3. Create your customized DAT derivative by adding one of the transformations indicated in the table below directly behind the derivative URL.

##### Fill

The below fill operations will first resize the smallest side of the image based on the specified dimensions. The long side of the image will be resized accordingly. The remaining part of the long side may be cropped taking into consideration the focal point.

When setting a manual focus point the first value is the X axis and the second value is the Y axis. For the X axis 0 is the left corner of the image and 1 is the right corner of the image. For the Y axis 0 is the top corner of the image and 1 is the bottom corner.

Parameters

Explanation & Result

Crop Circular Shapes

Defined in Database

?io=transform:crop,shape:circle,width:500,height:500

?io=transform:crop,shape:circle,width:300,height:200

?io=transform:crop,shape:circle,width:500,height:500,blur:88

The image will be cropped with a circular shape around the focus point.

If the width is the same as the height the shape will become a circle.

If the width is larger than the height the shape will become a landscape oval.

If the width is smaller than the height the shape will become a portrait oval.

You can add blurred edges to circular shapes by adding blur to the parameter. The supported blur range lies between 0 and 100 where 0 is no blur and 100 is the maximum blur.

Background Color

Not Applicable

?io=background:yellow

?io=background:fff00

?io=background:auto

### Tip

The color can be indicated by its name (yellow), with an hexadecimal color code (fff00), or auto.

The system will fill the transparent layer of the image with the indicated color.

Rotation of Image

Not Applicable

?io=transform:rotate,angle:270

The system will rotate the image from 0 to 360 degrees.
