如何使用PDFBox drawString插入换行符 [英] How to Insert a Linefeed with PDFBox drawString

问题描述

我必须用表制作PDF。到目前为止它工作正常，但现在我想添加一个包装功能。所以我需要插入换行符。

I have to make a PDF with a Table. So far it work fine, but now I want to add a wrapping feature. So I need to insert a Linefeed.

contentStream.beginText();  
contentStream.moveTextPositionByAmount(x, y);  
contentStream.drawString("Some text to insert into a table.");  
contentStream.endText();  

我想添加一个 \ n 之前插入。我尝试了 \\\ 这是换行符的十六进制值，但Eclipse向我显示错误。

I want to add a "\n" before "insert". I tried "\u000A" which is the hex value for linefeed, but Eclipse shows me an error.

是否可以使用drawString添加换行符？

Is it possible to add linefeed with drawString?

推荐答案

pdf格式不知道换行符。你必须拆分字符串并使用moveTextPositionByAmount将文本位置移动到下一行。

The pdf format doesn't know line breaks. You have to split the string and move the text position to the next line, using moveTextPositionByAmount.

这不是一个特殊的pdfbox-feature，它是由于pdf格式定义;所以没有办法使用drawString，也没有其他方法可以调用支持换行。

This is not a special "pdfbox-feature", it is due to the pdf format definition; so there is no way for drawString and there are also no other methods to be called that support linefeeds.
