【问题描述】:
我正在使用 Apache PDFBox java 库来创建 PDF。但是,我在呈现多行文本(换行)时遇到问题:
//Creating PDF document object
PDDocument doc = new PDDocument();
//Adding the blank page to the document
doc.addPage( new PDPage() );
PDPage page = doc.getPage(0);
PDImageXObject pdImage = PDImageXObject.createFromFile("C:\\Users\\abc\\Desktop\\abc.png", doc);
PDPageContentStream contentStream = new PDPageContentStream(doc, page);
contentStream.drawImage(pdImage, 10, 720);
//Begin the Content stream
contentStream.beginText();
contentStream.newLineAtOffset(50, 735);
//Setting the font to the Content stream
contentStream.setFont( PDType1Font.TIMES_ROMAN, 16 );
contentStream. showText("ABC Management System");
//Setting the leading
//contentStream.setLeading(14.5f);
//Setting the position for the line
contentStream.newLineAtOffset(25, 600);
String text1 = "This is an example of adding text to a page in the pdf document we can add as many lines";
String text2 = "as we want like this using the ShowText() method of the ContentStream class";
//Adding text in the form of string
contentStream. showText(text1);
contentStream.newLine();
contentStream. showText(text2);
//Ending the content stream
contentStream.endText();
System.out.println("Content added");
//Closing the content stream
contentStream.close();
//Saving the document
doc.save("my_doc.pdf");
System.out.println("PDF created");
//Closing the document
doc.close();
我面临的问题是文本的后半部分(text1、text2)没有在 PDF 文件中呈现。 pdf中只显示图片和第一行ABC Management System。
为了生成多行文本,我参考了:PDFBox - Adding Multiple Lines。
我不明白 setLeading 做了什么,因此将其注释掉并再次尝试,但文本仍未呈现。
【问题讨论】:
-
@TilmanHausherr 它奏效了。谢谢!
-
@TilmanHausherr 有没有办法改变背景颜色?
-
您必须以适当的非描边颜色绘制一个矩形。
-
@HBK 更多自动换行,您可能想从this answer 寻找灵感。
