Java PPT转PDF 亲测无水印

最近，需要将PPT文件转换为PDF。经过长时间的转换，一直有水印。最后，我找到了去除水印的方法来记录它。

自带jar包

本地安装jar命令：

mvn install:install-file -Dfile="C:/Users/DELL/Desktop/aspose.slides-15.9.0.jar" -DgroupId=com.aspose -DartifactId=aspose-slides -Dversion=15.9.0 -Dpackaging=jar

下面的上代码块(全部见下面的AsposeUtil代码)：

/** * ppt to pdf * @param inputStream */@SneakyThrowspublic static ByteArrayInputStream ppt2PDF(InputStream inputStream) {// Licenseiff验证 (!getLicenseq()) {return null;}try {Presentation ppt = new Presentation(inputStream);ByteArrayOutputStream dstStream = new ByteArrayOutputStream();ppt.save(dstStream, com.aspose.slides.SaveFormat.Pdf);ByteArrayInputStream inputstream1 = parse(dstStream);return inputstream1;} catch (Exception e) {e.printStackTrace();}return null;}

/** * licence 验证 * * @return * @throws Exception */public static boolean getLicenseq() throws Exception {boolean result = false;try {InputStream is = AsposeUtil.class.getResourceAsStream("/slides/license.xml");com.aspose.slides.License aposeLic = new com.aspose.slides.License();aposeLic.setLicense(is);result = true;is.close();} catch (Exception e) {e.printStackTrace();throw e;}return result;}
