获取单选按钮选项

PDF 表单中的单选按钮字段是分组控件，一次只能选择一个选项。每个组都有字段名称，每个选项都有相应的值。

1. 创建 Form 对象。
2. 绑定 PDF 文档。
3. 检索已选的单选按钮选项。

from io import FileIO
import sys
from os import path
import aspose.pdf as ap
import aspose.pdf.facades as pdf_facades

sys.path.append(path.join(path.dirname(__file__), ".."))

from config import set_license, initialize_data_dir


# Get radio button options
def get_radio_button_options(infile):
    """Get radio button options from a PDF document."""
    # Create Form object
    pdf_form = pdf_facades.Form()

    # Bind PDF document
    pdf_form.bind_pdf(infile)

    # Get radio button options by their names
    field_names = ["WorkType"]
    for field_name in field_names:
        options = pdf_form.get_button_option_current_value(field_name)
        print(f"Options for '{field_name}': {options}")
