Set Parameter to Link IM Variable to Property Variable for both.

Create an instance of this behavior for each variable.

Link the Image and Video Manager variables you created earlier to the Property Manager variables you just populated using the Set Parameter behavior. This assumes that you use a consistent URL structure like the following URL: Use an offset of 2 for the PMUSER_WIDTH variable, and an offset of 3 for the PMUSER_HEIGHT variable. Use the Path Component Offset feature to extract the dimensions. This rule must come before the rule containing your primary Image and Video Manager rule in the rule tree.Įxtract the image dimensions from your URL and assign them to the PMUSER_WIDTH and PMUSER_HEIGHT variables you just created using the Set Variable behavior. You will use these to populate the Image and Video Manager variables you created in Image Policy Editor.Ĭreate a new child rule under your default rule and call it IM Variables. This prevents accidental enlargement of the original image if incorrect dimensions are published in the URL.Ĭreate two Property Manager variables: one called PMUSER_WIDTH and another called PMUSER_HEIGHT. Set Constraint Type to Downsize to make sure that resized images are limited to the same size or smaller than the original image. The resulting image is the smallest possible that meets the height and width specified.

This resizes the image to completely fill the given dimensions. Set default values for both variables to account for cases where dimensions may not be present in the image URL. The values for these variables will be populated by Property Manager in a later step. in the Policy Variables editor, create two new variables: one called width, and one called height.Click Variable in the Width field and select Add Variable.Change Fixed Value to Variable for both parameters.Give your new policy a name, for example, "resize".Ĭlick + to open the list of Transformations.Select the policy set to which you wish to add the new policy.Click +Create, then click Policy on the menu that appears.Select the correct Contract from the list.

The URL of the original image that Image and Video Manager requests actually looks something like this: Those directories don't actually exist at your origin. It's worth noting that the desired width (900px) and height (600px) of the resized image exist as virtual directories in the URL. The URL for the image must be on your domain and contain image dimensions in the path, for example: Using both Image and Video Manager and Property Manager it's possible to extract those dimensions and use them to dynamically resize images without having to change any existing URLs. This is particularly useful if you want to allow a creative team to resize images without giving them access to Image and Video Manager.Ī specific example is published image dimensions in the URL path. In addition to resizing images using hard coded dimensions, you can use Image and Video Manager to dynamically resize images based on published dimensions.
