用于将 PS 导出为 PPSX 的 Java API

// open PS document
Document doc = new Document("input.ps", "Your@Password");
// save PS as PPTX format 
document.save("PptxOutput.pptx", SaveFormat.Pptx); 

// instantiate a Presentation object that represents a PPTX file
Presentation presentation = new Presentation("PptxOutput.pptx");
// set view type
presentation.getViewProperties().setLastView((byte) ViewType.SlideMasterView);
// save the presentation as Ppsx format
presentation.save("output.ppsx", SaveFormat.Ppsx);
