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.

Android API to Export PS to OTP
- Open PS file using Document class
- Convert PS to PPTX by using save method
- Load PPTX document by using Presentation class
- Save the document to OTP format using
save
method and set
Otp
as SaveFormat
Get Started with Java File Format APIs
You can easily use Aspose.Total for Android via Java directly from Maven and install Aspose.PDF for Android via Java and Aspose.Slides for Android via Java in your applications.
Alternatively, you can get a ZIP file from downloads .
// load PS file with an instance of Document class
Document document = new Document("template.ps");
// 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");
// save the presentation as Otp format
presentation.save("output.otp", SaveFormat.Otp);
Open Password Protected PS File in Android via Java
While loading PS file format, your document might be password protected. Aspose.PDF for Android via Java allows you open encrypted documents as well. In order to open the encrypted file, you can initialize new instance of the Document class and pass filename and password as arguments.
// open PS document
Document doc = new Document("input.ps", "Your@Password");
// save PS as PPTX format
document.save("PptxOutput.pptx", SaveFormat.Pptx);
Create Thumbnail Image of OTP File in Android Applications
After converting PS to OTP, you can also create thumbnail images of your output document. By using rich in feature Aspose.Slides for Android via Java you can generate thumbnail images of the slides by creating and instance of the Presentation class. After that, you can obtain the reference of any desired slide by using its ID or index and get the thumbnail image of the referenced slide on a specified scale.
// instantiate a Presentation object that represents a OTP file
Presentation presentation = new Presentation("output.otp");
// access the first slide
ISlide sld = pres.getSlides().get_Item(0);
// create a full scale image
BufferedImage image = sld.getThumbnail(1f, 1f);
// save the image to disk in PNG format
ImageIO.write(image, "PNG", new java.io.File("Thumbnail_out.png"));

What is PS File Format?
The PS (PostScript) file format is a page description language developed by Adobe Systems. It is commonly used for printing and is supported by a wide range of printers and imaging devices. PS files contain instructions that describe how elements such as text, images, and graphics should be rendered on a printed page.
PS files are created by applications that generate PostScript output, such as Adobe Illustrator, Adobe InDesign, or other graphics software. They are primarily used in professional printing workflows, where high-quality and consistent output is required.
The PS file format is based on a stack-based programming language, where commands and operands are placed on a stack and executed in a sequential manner. This allows for precise control over page layout, typography, color, and other printing parameters.
PS files are typically text-based and can be opened and edited with a text editor. They consist of a series of ASCII characters that represent the PostScript code. The code describes the arrangement and appearance of objects on a page, including text positioning, image placement, and graphical transformations.
While PS files are primarily used for printing, they can also be converted to other formats for digital distribution or further processing. For example, PS files can be converted to PDF (Portable Document Format) files, which are widely supported and can be easily viewed and printed on various devices.
What is OTP File Format?
The OpenDocument Standard Format (ODF) serves as an XML-based file format for representing various electronic documents, including spreadsheets, charts, presentations, and word processing documents. The format is standardized by the Organization for the Advancement of Structured Information Standards (OASIS) and was initially adopted by ISO/IEC JTC1 SC34 in 2005. One of the key advantages of ODF is that it is an open format, meaning it is not restricted by copyright or patent limitations.
ODF is built upon the XML schema derived from the OpenOffice.org office suite and employs the Zip compression algorithm. Its design objective is to be platform-independent, enabling support across a wide range of applications and operating systems.
The ODF specification defines three main document types: text documents, spreadsheets, and presentations. Each document type corresponds to a specific XML schema. These schemas are designed to be extensible, allowing for the addition of application-specific features.
ODF documents have the capability to be encrypted and signed using the XML Encryption and XML Signature standards. This provides security and integrity options for sensitive or important documents.
Numerous office applications support the OpenDocument Format, including Apache OpenOffice, LibreOffice, IBM Lotus Symphony, and even Microsoft Office. This broad support ensures compatibility and facilitates the exchange and collaboration of documents across different software platforms.
