如何在Apache POI ppt中添加自定义字体

问题描述

我能够添加Apache POI ppt中默认的字体，但不能添加自定义字体.这是我目前拥有的:

I am able to add fonts which are default in Apache POI ppt but not able to add custom fonts. This is what I currently have:

XSLFTextBox categoryTitleShape = indexslide.createTextBox();
categoryTitleShape.setAnchor(new java.awt.Rectangle(25, 40, 120, 30));
XSLFTextRun categoryTitle = categoryTitleShape.addNewTextParagraph().addNewTextRun();
categoryTitle.setText("CATEGORIES"); // visible text
categoryTitle.setFontSize(20.);
categoryTitle.setFontColor(Color.BLACK);
categoryTitle.setBold(true);
categoryTitle.setFontFamily(HSSFFont.FONT_ARIAL, FontGroup.EAST_ASIAN);

上面的代码添加了Apache POI ppt中可用的字体，但是我需要添加自定义字体.请帮忙.

The above code adds fonts which are available in Apache POI ppt, but I need to add custom fonts. Please help.

推荐答案

Microsoft Office文档中似乎可以嵌入字体.至少在PowerPoint和Word中.请参见如何在PowerPoint中嵌入字体和如何在文档中嵌入TrueType字体.但是不幸的是，apache poi不支持将此字体文件存储在Office Open XML文档文件的/fonts/部分中.

There seems to be a font embedding possible in Microsoft Office documents. At least in PowerPoint and Word. See How to embed fonts in PowerPoint and How to embed a TrueType font in a document. But unfortunately apache poidoes not supporting storing this font files in /fonts/ part of the Office Open XML document files.

因此，使用apache poi直到现在，必须在操作系统中安装使用的字体.我们只能在 XSLFTextRun.setFontFamily .如果在操作系统中安装了该字体，则将使用它，否则，如果呈现文件，则会猜测出类似的字体.

So using apache poi until now the fonts used must be installed in the operating system. We only can give a string as the typeface in XSLFTextRun.setFontFamily. If this font is installed in the operating system, then it will be used, else a similar font will be guessed if the file is rendered.

示例:

import java.io.FileOutputStream;

import org.apache.poi.xslf.usermodel.*;
import org.apache.poi.sl.usermodel.*;

import java.awt.Rectangle;

public class CreatePPTXTextBoxSpecialFont {

 public static void main(String[] args) throws Exception {

  XMLSlideShow slideShow = new XMLSlideShow();

  XSLFSlide slide = slideShow.createSlide();

  XSLFTextBox textbox = slide.createTextBox();
  textbox.setAnchor(new Rectangle(50, 100, 570, 100));
  XSLFTextParagraph paragraph = textbox.addNewTextParagraph();
  XSLFTextRun run = paragraph.addNewTextRun();
  run.setText("Arial ");
  run.setFontFamily("Arial");
  run.setFontSize(24d);
  run = paragraph.addNewTextRun();
  run.setText("Algerian ");
  run.setFontFamily("Algerian");
  run.setFontSize(24d);
  run = paragraph.addNewTextRun();
  run.setText("Courier ");
  run.setFontFamily("Courier");
  run.setFontSize(24d);
  run = paragraph.addNewTextRun();
  run.setText("Times New Roman ");
  run.setFontFamily("Times New Roman");
  run.setFontSize(24d);

  FileOutputStream out = new FileOutputStream("CreatePPTXTextBoxSpecialFont.pptx");
  slideShow.write(out);
  out.close();
 }
}
