如何添加一个链接到PdfSharp文件？ [英] How do I add a link to a file in PdfSharp?

问题描述

我似乎无法得到PdfSharp以显示此标注的图片。它不具有PdfAnnotation.Icon财产，所以我不能设置。

I can't seem to get PdfSharp to show a picture for this annotation. It doesn't have the PdfAnnotation.Icon property, so I can't set that.

XFont font = new XFont("Verdana", 10);
        PdfPage page = wDoc.Parent.Page;
        XGraphics gfx = wDoc.Parent.gfx;
        XRect rec = gfx.Transformer.WorldToDefaultPage(new XRect(new XPoint(30, 60), new XSize(30, 30)));
        PdfRectangle rect = new PdfRectangle(rec);
        PdfLinkAnnotation link = PdfLinkAnnotation.CreateFileLink(rect, wDoc.FileLocation);
        gfx.DrawString("These files were attached:", font, XBrushes.Black, 30, 50, XStringFormat.Default);
        gfx.
        link.Rectangle = new PdfRectangle(rec);
        page.Annotations.Add(link);

我已经得到了那么远，与注解确实存在，但它是一个空白框！我该如何去使它说些什么，甚至只是出现画面？

I've gotten it that far, and the annotation DOES exist, except it's a blank box! How do I go about making it say something, or even just show a picture?

推荐答案

您需要使用page.AddWebLink（AREArect），然后用gfx.drawstring添加文本区域（AREArect）

You need to use page.AddWebLink(AREArect) and then add the text area with gfx.drawstring(AREArect)
