问题描述

我想在使用 PDFBOX 创建的PDF中添加超链接，这样我点击一些文字示例'点击此处'将重定向到网址。我尝试使用 PDAnnotationLink 和 PDActionURI ，但是如何将其添加到 contentstream ？

I want to add a hyperlink in PDF created using PDFBOX, such that i click on some text example 'Click here' will redirect to URL. I tried using PDAnnotationLink and PDActionURI, but how to add it in contentstream?

PDBorderStyleDictionary borderULine = new PDBorderStyleDictionary();
borderULine.setStyle(PDBorderStyleDictionary.STYLE_UNDERLINE);
PDAnnotationLink txtLink = new PDAnnotationLink();
txtLink.setBorderStyle(borderULine);
txtLink.setColour(colourBlue);

// add an action
PDActionURI action = new PDActionURI();
action.setURI("www.google.com");
txtLink.setAction(action);

contentStream.beginText();
contentStream.moveTextPositionByAmount(400, y-30);
contentStream.drawString(txtLink);----error
contentStream.endText();

推荐答案

添加到 contentStream 使用以下代码

    PDRectangle position = new PDRectangle();
    position.setLowerLeftX(10);
    position.setLowerLeftY(20); 
    position.setUpperRightX(100); 
    position.setUpperRightY(10); 
    txtLink.setRectangle(position);
    page.getAnnotations().add(txtLink);
