Content awareness crop #3646

Closed megetron closed 1 year ago

Is there an option with sharp to crop image by the image content?

I have some images with white background and an object in the middle of the image. Looking for a way to remove the white padding that surrounding the image and then resize it.

This will help keep all objects on the same size which result a nice list layout. Can sharp do this? /

Did you see position property of resize()? The entropy and attention strategies can be used to "smartcrop" an image to the target dimensions.

sharp(input).resize({ width: 100, height: 100, position: 'attention' })...
