When uploading images, you can automatically crop the image upon upload by applying an Image Profile to the folder.
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. For example, if the image displays 150 ppi and you enter 75 in the Top, Right, Bottom, and Left text boxes, a half-inch is cropped from each side.
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 will be ignored. This effect uses the same options as Adobe Photoshop’s “Unsharp Mask” filter.
Bemærk:
Unsharp mask is only applied to downscaled renditions within the ptiff that are downsampled more than 50%. That means that the largest-sized renditions within the ptiff are not affected by unsharp mask whereas smaller-sized renditions such as thumbnails are altered (and will show the unsharp mask).
In Unsharp Mask, you have the following options:
- 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 5.0. Think of Amount as a measure of filter intensity.
- 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.
- 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 .02 and 0.2. The default value is 2.
Sharpening is described in Sharpening Images.

To create an image profile:
When you assign an image profile to a folder, any subfolders automatically inherit the profile from its parent folder. This 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 name of the profile appearing in the card.

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.
In addition to applying a profile to a folder, you can also apply one globally so that any content uploaded into AEM assets in any folder has the selected profile applied.
To apply a profile globally, do one of the following:
When you remove an image profile from a folder, any subfolders automatically inherit the removal of the profile from its parent folder. However, any processing of files that has occurred within the folders remains intact.
