Sure, let me check with latest jar.
Also below is the Java code which we are using for converting of HTML to pptx
try {
File file = ResourceUtils.getFile(“classpath:GroupDocs.Conversion.Java.lic”);
InputStream stream = new FileInputStream(ResourceUtils.getFile(“classpath:GroupDocs.Conversion.Java.lic”));
if (file.exists())
{
License license = new License();
license.setLicense(stream);
System.out.println("License set successfully.");
}
else
{
System.out.print("\nWe do not ship any license with this example. " +
"\nVisit the GroupDocs site to obtain either a temporary or permanent license. " +
"\nLearn more about licensing at https://purchase.groupdocs.com/faqs/licensing. " +
"\nLear how to request temporary license at https://purchase.groupdocs.com/temporary-license.");
}
OutputStream outputStream = response.getOutputStream();
response.setContentType("application/vnd.ms-powerpoint");
response.setHeader("Content-Disposition", "attachment;filename=\"" + pptName + ".ppt\"");
PresentationConvertOptions options = new PresentationConvertOptions();
InputStream inputStream = IOUtils.toInputStream(pptReport.getHtml(), StandardCharsets.UTF_8);
Converter converter = new Converter(inputStream);
converter.convert(outputStream,options);
responseEntity = new ResponseEntity(HttpStatus.OK);
ppt.write(outputStream);
ppt.close();
