PDF 表單

IronPDF for Python可以從HTML建立互動式PDF表單，並以程式的方式讀取或寫入現有PDF表單的欄位值。

入門指南

在渲染包含RenderingOptions.CreatePdfFormsFromHtml = True啟用表單建立。要在現有表單中讀取或寫入欄位值，請載入PDF並使用Form.FindFormField。

理解程式碼

建立表單

CreatePdfFormsFromHtml = True：在渲染時將HTML表單元素 (<checkbox> 等) 轉換為互動式PDF表單欄位。
RenderHtmlAsPdf(form_html)：將HTML表單渲染為帶有互動可填寫欄位的PDF。 SaveAs("BasicForm.pdf")將其寫入磁碟。
