| <li>Basic: The bounding box (bbox) is the tuple of four floats for the rectangular corners: left, top, right, bottom in the normalized ratio. The Word prompt indices is a list of 1-indexed numbers determining the prompt word.</li> | |
| <li>Advanced Options: We also offer some key parameters to adjust the synthesis result. Please see our paper for more information about the ablations.</li> | |
