    PDF: Просмотр интерактивных полей PDF документа в WPF
    В этом разделе
    Поля интерактивной формы PDF документа могут быть отображены на PDF странице в WPF просмотрщике изображений с помощью визуального инструмента - WpfPdfAnnotationTool.

    Внешний вид интерактивного поля определяется классом PdfWidgetAnnotation, экземпляр которого можно получить с помощью свойства PdfInteractiveFormField.Annotation. Для каждого типа интерактивного поля реализован тип аннотации, который определяет, как отображается интерактивное поле и как пользователь может с ним взаимодействовать:
    Класс WpfPdfAnnotationTool позволяет отображать интерактивные поля в двух режимах: 'None' и 'View'.

    В режиме 'None' класс WpfPdfAnnotationTool:
    В режиме 'View' класс WpfPdfAnnotationTool:
    Вот C#/VB.NET код, который демонстрирует, как отобразить интерактивные поля PDF документа в WPF просмотрщике изображений:

    Класс WpfPdfAnnotationTool имеет свойство WpfPdfAnnotationTool.ActionExecutor, которое используется для выполнения действий в PDF при возникновении событий интерактивного поля. По умолчанию свойство WpfPdfAnnotationTool.ActionExecutor представляет собой составной исполнитель действий, который может выполнять различные типы действий. Например, класс PdfJavaScriptActionExecutor выполняет действия на JavaScript в PDF, то есть исполняет код JavaScript с помощью интерпретатора JavaScript.
