Java如何在iText中设置段落行间距？
要设置的行间距在iText的段落可以通过传递线空间/领先的参数进行Paragraph构造。在下面的示例中，我们将行距设置为32。我们还可以通过调用此对象的setSpacingBefore()和setSpacingAfter()方法来设置段落之间的间隔。
package org.nhooo.example.itextpdf;
import com.itextpdf.text.Chunk;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class ParagraphLineSpaceDemo {
public static void main(String[] args) {
Document doc = new Document();
try {
FileOutputStream fos = new FileOutputStream("ParagraphLineSpace.pdf");
PdfWriter.getInstance(doc, fos);
doc.open();
String content = "The quick brown fox jumps over the lazy dog";
//将段落行距设置为32
Paragraph para1 = new Paragraph(32);
//在段落之前和之后设置空间
para1.setSpacingBefore(50);
para1.setSpacingAfter(50);
for (int i = 0; i < 10; i++) {
para1.add(new Chunk(content));
}
doc.add(para1);
Paragraph para2 = new Paragraph();
for (int i = 0; i < 10; i++) {
para2.add(new Chunk(content));
}
doc.add(para2);
doc.close();
} catch (DocumentException | FileNotFoundException e) {
e.printStackTrace();
}
}
