Hey Support team,
Thanks for considering Aspose.
You can hide shapes by using setHidden method of Shape class. Please visit this documentation link. Please use the following code snippet to hide the shape in your presentation file.
//Instantiate a Presentation object that represents a PPT file
Presentation pres = new Presentation(“d:\pptx\test.ppt”);
//Accessing a slide using its slide position
Slide slide = pres.getSlideByPosition(1);
//Accessing first shape
Shape shp = slide.getShapes().get(0);
//Hide the shape
//Writing the presentation as a PPT file
