How to Increase the Page Size and the Size of the Contents?

I am using aspose slides- java to convert pptx to pdf.
The converted pdf is going to be a part of another pdf which has page size A2.
How can i increase the page size and the size of the contents as well.
I was able to increase height and width of the page while converting. But the contents in the file remain of the same size. How can i scale them up accordingly.


Thank you for posting the inquiry.

Please try to change the size of slides as shown below:

presentation.getSlideSize().setSize(1684, 1190, SlideSizeScaleType.Maximize);

Documents: Slide Size
API Reference: ISlideSize Interface

This worked well for almost everything except a couple of slides which have Hierarchy.
Hierarchy falls under SmartArt in Popwerpoint. And that is something which is not working. What can be done?

I found this but could not get much out of this. Please help.

This is the code i am using

public ConvertPPTToPDF(String filePath,String pageHeight,String pageWidth) throws Exception
	destinationFilePath = processFileNamesForExtensionReplace(filePath,"pdf");
	Presentation pres = new Presentation(filePath);
	//pres.getSlideSize().getSize().setSize(3600, 2000);
	pres.getSlideSize().setSize( Float.parseFloat(pageHeight),Float.parseFloat(pageWidth), SlideSizeScaleType.Maximize);
	System.out.println(pres.getSlideSize().getSize());, SaveFormat.Pdf);
