How to use the illegality test function？

Dear author, I have a question here. I don't know how to set parameters to support negative testing. In PICT, you only need to mark a '~' sign before the parameter to generate a negative case.How can i generatea negative cases in pypict? I hope you can help me,thank you very much!

Unfortunately that is a feature of PICT Command; it is not available in PICT C API layer.
If you are familiar with PICT's model syntax, you can use pypict.cmd.from_model(your_model_text) which uses PICT Command, instead of pypict.tools.from_dict(your_model_dict) which uses PICT C API.
