Gebruik dit endpoint om een afbeelding buiten de oorspronkelijke randen uit te breiden wanneer je meer canvas rond de broninhoud nodig hebt.

​
Hoe de uitbreidingsverhoudingen werken

  • Elke verhouding wordt gemeten ten opzichte van de oorspronkelijke breedte of hoogte
  • Het gecombineerde uitgebreide canvas moet nog steeds binnen de door Kling gedocumenteerde oppervlaktelimieten blijven
  • Begin met kleine waarden zoals 0.1 aan elke zijde voordat je grotere uitbreidingen probeert

​
Huidige beschikbaarheid

  • De gedocumenteerde route is POST /kling/v1/images/editing/expand
  • Dit endpoint geeft een 404-respons terug
