AEM 6.4 has reached the end of extended support and this documentation is no longer updated. For further details, see our technical support periods. Find the supported versions here.

When uploading images, you can automatically crop the image upon upload by applying an Image Profile to the folder.

NOTE
Smart Crop is available only in Dynamic Media - Scene7 mode.
IMPORTANT
Image Profiles are not applicable to PDF, animated GIF, or INDD (Adobe InDesign) files.

Crop options crop-options

When you implement Smart Crop on images, Adobe recommends the following best practice and enforces the following limit:

Limit type
Best practice
Limit imposed
Number of Smart Crops per image
5
100

See also Dynamic Media limitations.

Smart Crop coordinates are aspect ratio dependent. That is, for each smart crop setting in an Image Profile, if the aspect ratio is the same for the added dimensions in the Image Profile, then the same aspect ratio is sent to Dynamic Media. As a result, Adobe recommends that you use the same crop area. Doing so ensures that there is no impact to different dimensions used in the Image Profile.

Each Smart Crop generation that you create requires extra processing. For example, adding more than five Smart Crop aspect ratios can result in a slow asset ingestion rate. It may also cause an increased load on systems. Because you can apply Smart Crop at the folder level, Adobe recommends that you use it on folders only where it is needed.

Guidelines for defining Smart Crop in an Image Profile
To keep Smart Crop usage under control, and to optimize for processing time and storage of crops, Adobe recommends the following guidelines and tips:

  • Avoid creating duplicate smart crop profiles that have the same width and height values.
  • Name smart crops based on crop dimensions, not on end usage. Doing so helps to optimize for duplicates where a single dimension is used on multiple pages.
  • Create page-wise/asset type-wise Image profiles for specific folders and subfolders instead of a common smart crop profile that is applied to all folders or all assets.
  • An Image profile that you apply to subfolders overrides an Image profile that is applied to the folder.
  • Create page-wise/asset type-wise Image Profiles for specific folders and subfolders instead of a common smart crop profile that is applied to all folders or all assets.
  • An Image Profile that you apply to subfolders overrides an Image Profile that is applied to the folder.
  • Ideally, have 10-15 smart crops per image to optimize for screen ratios and processing time.

You have two image crop options from which to choose. You can also choose to automate the creation of color and image swatches or preserve crop content across target resolutions.

IMPORTANT
• Adobe recommends that you review any generated crops and swatches to ensure that they are appropriate and relevant to your brand and values.
• CMYK image format is not supported with smart crop.
Option
When to use
Description
Pixel Crop
Bulk crop images based on dimensions only.

To use this option, select Pixel Crop from the Cropping Options drop-down list.

To crop from the sides of an image, you enter the number of pixels to crop from any side or each side of the image. How much of the image is cropped depends on the ppi (pixels per inch) setting in the image file.

An Image Profile pixel crop renders in the following manner:

  • Values are Top, Bottom, Left, and Right.
  • Top left is considered 0,0 and the pixel crop is calculated from there.
  • Crop starting point: Left is X and Top is Y
  • Horizontal calculation: horizontal pixel dimension of original image minus Left and then minus Right.
  • Vertical calculation: vertical pixel height minus Top, and then minus Bottom.

For example, suppose you have a 4000 x 3000 pixel image. You use values: Top=250, Bottom=500, Left=300, Right=700.

From Top Left (300,250) crop using the fill space of (4000-300-700, 3000-250-500, or 3000,2250).

Smart Crop
Bulk crop images based on their visual focal point.

Smart Crop uses the power of artificial intelligence in Adobe Sensei to quickly automate the cropping of images in bulk. Smart Crop automatically detects and crops to the focal point in any image to capture the intended point of interest, regardless of screen size.

To use Smart Crop, select Smart Crop from the Cropping Options drop-down list, then to the right of Responsive Image Crop, enable (turn on) the feature.

The default breakpoint sizes of Large, Medium, and Small generally cover the full range of sizes that most images are used on mobile and tablet devices, desktops, and banners. If desired, you can edit the default names of Large, Medium, and Small.

To add more breakpoints, click Add Crop; to delete a crop, click the Garbage Can icon.

Color and Image Swatch
Bulk generate an image swatch for each image.

Note: Smart Swatch is not supported in Dynamic Media Classic.

Automatically locate and generate high-quality swatches from product images that show color or texture.

To use Color and Image Swatch, select Smart Crop from the Cropping Options drop-down list, then to the right of Color and Image Swatch, enable (turn on) the feature. Enter a pixel value in the Width and Height text boxes.

While all image crops are available from the Renditions rail, swatches are only used by way of the Copy URL feature. It's required that you use your own viewing component to render the swatch on your site. (The exception to this rule is carousel banners. Dynamic Media provides the viewing component for the swatch used in carousel banners.)

Using image swatches

The URL for image swatches is straightforward:

/is/image/company/<asset_name>:Swatch

where :Swatch is appended to the asset request.

Using color swatches

To use color swatches, you make a req=userdata request with the following:

/is/image/<company_name>/<swatch_asset_name>:Swatch?req=userdata

For example, the following is a swatch asset in Dynamic Media Classic:

https://my.company.com:8080/is/image/DemoCo/Sleek:Swatch

and here is the swatch asset's corresponding req=userdata URL:

https://my.company.com:8080/is/image/DemoCo/Sleek:Swatch?req=userdata

The req=userdata response is as follows:

SmartCropDef=Swatch SmartCropHeight=200.0 SmartCropRect=0.421671,0.389815,0.0848564,0.0592593,200,200 SmartCropType=Swatch SmartCropWidth=200.0 SmartSwatchColor=0xA56DB2

You can also request a req=userdata response in either XML or JSON format, as in the following respective URL examples:

https://my.company.com:8080/is/image/DemoCo/Sleek:Swatch?req=userdata,json

https://my.company.com:8080/is/image/DemoCo/Sleek:Swatch?req=userdata,xml

Note: You must create your own WCM component to request a color swatch and parse the SmartSwatchColor attribute, represented by a 24-bit RGB hexadecimal value.

See also userdata in the Viewers Reference Guide.

Unsharp Mask unsharp-mask

You use Unsharp Mask to fine-tune a sharpening filter effect on the final downsampled image. You can control intensity of effect, radius of the effect (measured in pixels), and a threshold of contrast that is ignored. This effect uses the same options as Adobe Photoshop’s “Unsharp Mask” filter.

NOTE
Unsharp mask is only applied to downscaled renditions within the PTIFF (pyramid tiff) that are downsampled more than 50%. That means the largest-sized renditions within the PTIFF are not affected by unsharp mask whereas smaller-sized renditions such as thumbnails are altered (and show the unsharp mask).

In Unsharp Mask, you have the following filtering options:

Option
Description
Amount
Controls the amount of contrast applied to edge pixels. The default is 1.75. For high-resolution images, you can increase it to as high as 5. Think of Amount as a measure of filter intensity. Range is 0-5.
Radius
Determines the number of pixels surrounding the edge pixels that affect the sharpening. For high-resolution images, enter from 1 through 2. A low value sharpens only the edge pixels; a high value sharpens a wider band of pixels. The correct value depends on the size of the image. The default value is 0.2. Range is 0-250.
Threshold
Determines the range of contrast to ignore when the unsharp mask filter is applied. In other words, this option determines how different the sharpened pixels must be from the surrounding area before they are considered edge pixels and are sharpened. To avoid introducing noise, experiment with values between 0-255.

Sharpening is described in Sharpening Images.

Creating Dynamic Media Image Profiles creating-image-profiles

To define advanced processing parameters for other asset types, see Configuring Asset Processing.

To create Dynamic Media Image Profiles:

  1. Tap the AEM logo and navigate to Tools > Assets > Image Profiles.

  2. Tap Create to add an Image Profile.

  3. Enter a profile name, and values for unsharp mask, crop, or swatch, or both.

    You may find it helpful to use a profile name that is specific to its intended purpose. For example, if you want to create a profile that generates swatches only—where Smart Crop is disabled and Color and Image Swatch is enabled—you could use the profile name “Smart Swatches”.

    See also Smart Crop and Smart Swatch Options and Unsharp Mask.

  3. If editing, save the changes. If deleting, confirm that you want to remove the profile.

Applying a Dynamic Media Image Profile to folders applying-an-image-profile-to-folders

When you assign an Image Profile to a folder, any subfolders automatically inherit the profile from its parent folder. This workflow means that you can assign only one Image Profile to a folder. As such, consider carefully the folder structure of where you upload, store, use, and archive assets.

If you assigned a different Image Profile to a folder, the new profile overrides the previous profile. The previously existing folder assets remain unchanged. The new profile is applied on the assets that are added to the folder later.

Folders that have a profile assigned to it are indicated in the user interface by the profile’s name appearing in the card.

When you add smart crop to an existing Image Profile, you must retrigger the DAM Update Asset workflow if you want to generate crops for existing assets in your asset repository.

You can apply Image Profiles to specific folders or globally to all assets.

Applying Dynamic Media Image Profiles to specific folders applying-image-profiles-to-specific-folders

You can apply an Image Profile to a folder from within the Tools menu or if you are in the folder, from Properties. This section describes how to apply Image Profiles to folders both ways.

Folders that have a profile already assigned to it are indicated by the display of the profile’s name directly below the folder name.

Applying Dynamic Media Image Profiles to folders from Profiles user interface applying-image-profiles-to-folders-from-profiles-user-interface

  1. Tap the AEM logo and navigate to Tools > Assets > Image Profiles.

  2. Select the Image Profile that you want to apply to a folder or multiple folders.
