Fill Generative Prompt
fill-gen-prompt
Premium Feature
Fill Generative Prompt is currently available for Imgix customers on a Premium plan. If you’re interested in this feature, please contact our sales team to get more information on this feature.
Provides a text suggestion to the output of fit=fill&fill=gen. It accepts URL-safe string values but can also be base64 encoded (fill-gen-prompt64). The shorthand version of this parameter can also be used (fill-gen-prompt).
Prefer Base64 Variant
Imgix recommends using the Base64 variant version of this parameter to make encoding values easier.
Limits
Guarantee of keyword output
While fill-gen-prompt suggests what the output generative fill should look like, it does not guarantee that the prompt keywords will be used in the final fill.
Character limits
There is no direct character limit for prompt values, though we recommend keeping your image URLs under 1024 characters.
