我正在尝试将 pptx 文件转换为图像，然后使用 apache poi 和 iText 创建 PDF。
Dimension pgsize = ppt.getPageSize();
XSLFSlide slide = ppt.getSlides()[0];
PdfWriter pdfWriter = null;
Document document = new Document()
pdfWriter = PdfWriter.getInstance(document, new FileOutputStream(targetPath));
document.setPageSize(new Rectangle((float) pgsize.getWidth(), (float) pgsize.getHeight()));
document.open();
PdfGraphics2D graphics = (PdfGraphics2D) pdfWriter.getDirectContent().createGraphics((float) pgsize.getWidth(),
(float) pgsize.getHeight());
slide.draw(graphics);
graphics.dispose();
document.close();
但我收到错误:

最佳答案
解决方案是不要混合 POI 版本。 Apache Tika 中已经有 POI
关于java - 使用 iText 和 PdfGraphics2D 的 PPTX 到 PDF 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53415615/
