for products on white backgrounds - dynamically crop white space out of product without cropping image subject


Level 1

We have product images on white backgrounds, we want to remove the white background by cropping to the image subject without cropping off any of the image subject, this currently happens with Smart Crop. We are using Dynamic Media with AEM Assets.

Hi @eezanke 


You can try to use this modifier to make the background transparent . Please append the same to the existing url and try "&fmt=webp-alpha"

Not the question really...I want to crop to the image subject, i.e. a chair that has a white background...so that the crop results in the edges of the image touching the edges of the chair...like this one below:

You can use the Knockout Background feature in Dynamic Media instead of Smart Crop. The Knockout Background feature automatically detects and removes the background color from an image during upload to AEM Assets. It analyzes the image corners to determine the background color, then makes that color transparent while keeping the subject intact

The below article about "Image fine-tuning options at upload" might help



Try and let us know if this works

Hi @eezanke ,

To dynamically crop white space out of product images without cropping the image subject, you can use the "Trim" feature in Dynamic Media with AEM Assets. The Trim feature automatically removes any whitespace around the edges of an image, while preserving the image subject.

Here's how you can use the Trim feature in Dynamic Media:

1. Open the Dynamic Media Image Preset Editor in AEM Assets.
2. Select the "Trim" option under the "Crop" section.
3. Set the "Trim Color" to "White" to remove white space around the edges of the image.
4. Save the Image Preset.

When you apply this Image Preset to your product images, Dynamic Media will automatically crop out any white space around the edges of the image, while preserving the image subject.

Note that the Trim feature works best when the white space around the image is consistent and uniform. If there are variations in the white space around the image, the Trim feature may not work as expected. In such cases, you may need to use other image processing techniques, such as manual cropping or Smart Crop, to achieve the desired result.
