如何在Apache POI ppt中添加自定义字体

XMLSlideShow ppt = new XMLSlideShow(new FileInputStream("your_ppt.pptx"));
XSLFSlideMaster slideMaster = ppt.getSlideMasters().get(0);

PackagePart fontPart = slideMaster.createPackagePart(new ContentType("application/vnd.ms-opentype"), "/ppt/fonts/font1.ttf");

OutputStream os = fontPart.getOutputStream();
Files.copy(Paths.get("path_to_your_font.ttf"), os);
os.close();

XSLFTextParagraph paragraph = slide.createParagraph();
XSLFTextRun run = paragraph.addNewTextRun();
run.setText("Custom Font Example");
run.setFontFamily("Your Custom Font");
run.setFontSize(24.0);

XSLFTextShape shape = slide.createTextBox();
shape.setText("Custom Font Example");
shape.setTextAutofit(TextAutofit.NORMAL);
shape.setAnchor(new Rectangle2D.Double(50, 50, 400, 200));
XSLFTextParagraph paragraph = shape.addNewTextParagraph();
XSLFTextRun run = paragraph.addNewTextRun();
run.setText("Custom Font Example");
run.setFontFamily("Your Custom Font");
run.setFontSize(24.0);

FileOutputStream out = new FileOutputStream("output.pptx");
ppt.write(out);
out.close();
ppt.close();
