Я хочу реализовать iTextSharp FontProvider в ironPython, следуя этому сообщению iText + HTMLWorker - Как изменить шрифт по умолчанию? .
Мой код всегда выбрасывает: TypeError: GetFont () принимает ровно 8 аргументов (дано 7).
$ ipy itexthtml.py
[INFO] __init__ .. AngsanaUPC
Traceback (most recent call last):
File "itexthtml.py", line 74, in <module>
File "itexthtml.py", line 65, in main
TypeError: GetFont() takes exactly 8 arguments (7 given)
Не знаю, что не так, Можно ли помочь?
Мой код Python.
import clr
clr.AddReference("itextsharp")
