When using SDXL ControlNet (e.g., canny control), the output image size is determined by the explicit width and height parameters in your API request: The input control signal image will be automatically:
  • Resized to fit your specified dimensions
  • Cropped to preserve aspect ratio
Example: To generate a 768x1344 image, explicitly include these parameters in your request: 
{
    "width": 768,
    "height": 1344
}
Note: While these parameters may not appear in the web interface examples, they are supported API parameters that can be included in your requests.
