I’m working on a PowerPoint reader using Aspose.Slides at the moment. I’ve also used Aspose.Words extensively. I’ve been learning about the DOM that Slides uses, but I notice, that text paragraphs do in Aspose.Slides not have a top level “style” the way paragraphs do in Words, at least that was my interpretation of the DOM. It appears each portion of text is a distinct piece of text with its own formatting for fonts etc. The paragraph containing the portion does not have any global formatting of its own, apart from bullets and alignment. Is this correct?
Yes, that’s right for ppt format. There were only 2 levels of formatting. Portion by itself and Master. In pptx Microsoft added also middle level. So it’s possible there to set default formatting for all portions in a paragraph.
