| Feld | Typ | Pflicht | Beschreibung |
|---|---|---|---|
| source | object | Ja | The image. Either url or content_base64. |
| format | string | Nein | Output format. Both carry an alpha channel; WebP is markedly smaller. |
| alpha_matting | boolean | Nein | Refine the edge for hair and fur. Slower, and not always better — compare before using it by default. |
| crop_to_subject | boolean | Nein | Crop the result to the bounding box of what remained. |
| max_width | integer | Nein | Scale the result down so the width fits. Never scales up. |
| quality | integer | Nein | For WebP output. |
