Properties

Name	Type	Description
image	string	The sketch or line drawing image to use as structural guidance.
prompt	string	Text describing the desired output image including content, colors, textures, and style.
negative_prompt	string	Text describing elements to exclude from the output image.
control_strength	number	Controls how closely the output follows the input sketch. Higher values produce outputs more faithful to the sketch structure.
seed	integer	A value to control randomness in generation.
output_format	string	The output format of the generated image.
