# Frame identification

When using the "content" [crop](/image-processing/resize-and-padding.md#types-of-crop) fit type, the image content is analysed for better cropping result, f.e. to reduce the possibility of cutting objects on the photo.

Identified object will be put inside desired size that has vertical proportions (1000x1500). Remaining background will be filled with black color which has been automatically found.

```json
{
    "width": 1000,
    "height": 1500,
    "fit": {
        "crop": "content"
    }
}
```
