在java中如何将文本放入pdfbox中的矩形中？

我想在矩形中显示“连接我们”文本

contentStream.beginText();
contentStream.setFont(PDType1Font.TIMES_ROMAN, 10);
contentStream.newLineAtOffset(260, 240);            
contentStream.showText("Connect with Us:");
contentStream.endText();
contentStream.setNonStrokingColor(235,235,235);
contentStream.addRect(50, 200, 500, 100);
contentStream.fill();

我尝试使用此代码获取矩形中的文本，但没有看到矩形中的文本。

首先绘制文本

contentStream.beginText();
contentStream.setFont(PDType1Font.TIMES_ROMAN, 10);
contentStream.newLineAtOffset(260, 240);            
contentStream.showText("Connect with Us:");
contentStream.endText();
contentStream.setNonStrokingColor(235,235,235);
contentStream.addRect(50, 200, 500, 100);
contentStream.fill();

contentStream.beginText();
contentStream.setFont(PDType1Font.TIMES_ROMAN, 10);
contentStream.newLineAtOffset(260, 240);            
contentStream.showText("Connect with Us:");
contentStream.endText();

然后填充矩形

contentStream.setNonStrokingColor(235,235,235);
contentStream.addRect(50, 200, 500, 100);
contentStream.fill();

那么，会发生什么？你的矩形覆盖了文本

要解决这个问题，只需换一种方式，首先绘制矩形，重置非笔划颜色，然后在其上写字

contentStream.setNonStrokingColor(235,235,235);
contentStream.addRect(50, 200, 500, 100);
contentStream.fill();
contentStream.setNonStrokingColor(0,0,0);
contentStream.beginText();
contentStream.setFont(PDType1Font.TIMES_ROMAN, 10);
contentStream.newLineAtOffset(260, 240);            
contentStream.showText("Connect with Us:");
contentStream.endText();

你先画文本

contentStream.beginText();
contentStream.setFont(PDType1Font.TIMES_ROMAN, 10);
contentStream.newLineAtOffset(260, 240);            
contentStream.showText("Connect with Us:");
contentStream.endText();

然后填充矩形

contentStream.setNonStrokingColor(235,235,235);
contentStream.addRect(50, 200, 500, 100);
contentStream.fill();
