<h5 >1. Support image ref image. (Cartoon Ref image is not support now)</h5>
<h5 >2. Support Typesetting Style and Captioning.(By default, the prompt is used as the caption for each image. If you need to change the caption, add a # at the end of each line. Only the part after the # will be added as a caption to the image.)</h5>
<h5 >3. [NC]symbol (The [NC] symbol is used as a flag to indicate that no characters should be present in the generated scene images. If you want do that, prepend the "[NC]" at the beginning of the line. For example, to generate a scene of falling leaves without any character, write: "[NC] The leaves are falling."),Currently, support is only using Textual Description</h5>
<h5>Tips: Not Ready Now! Just Test! It's better to use prompts to assist in controlling the character's attire. Depending on the limited code integration time, there might be some undiscovered bugs. If you find that a particular generation result is significantly poor, please email me (ypzhousdu@gmail.com)  Thank you very much.</h4>
