Convert PS to OTP on Android via Java
Transform PS to OTP within your Android Applications without using Microsoft® PowerPoint or Adobe® Acrobat Reader
Why to Convert
The Portable Document Format (PDF) is a widely used file format for documents. It is used to store and share documents, and is often used for archiving and printing. However, PDFs are not always the best format for sharing documents. For example, if you need to make changes to a document, it is often easier to use a presentation format such as OpenDocument Presentation (OTP). Therefore, it is often necessary to convert PDFs to OTP.
