Render PS to OTP within C++ Applications
Convert PS to OTP within your C++ Applications without using Microsoft® PowerPoint
Are you a C++ developer looking to add to integrate PS to OTP conversion feature inside your C++ applications? You can do it in two simple steps. You can export PS to PPTX by using Aspose.PDF for C++ . Secondly, by using Aspose.Slides for C++ , you can convert PPTX to OTP. Both APIs come under Aspose.Total for C++ package.
C++ API to Export PS to OTP
- Open PS file using Document class reference
- Convert PS to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to OTP format using
Save
member function and set
Otpas SaveFormat
Get Started with C++ File Automation APIs
Install from command line as nuget install Aspose.Total.Cpp or via Package Manager Console of Visual Studio with Install-Package Aspose.Total.Cpp.
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load PS file with an instance of Document class
auto doc = MakeObject<Document>(u"template.ps");
// save PS as PPTX format
doc->Save(u"PptxOutput.pptx", SaveFormat::Pptx);
// instantiate a Presentation object that represents a PPTX file
SharedPtr<Presentation> prs = MakeObject<Presentation>(u"PptxOutput.pptx");
// save the presentation as Otp format
prs->Save(u"output.otp", Aspose::Slides::Export::SaveFormat::Otp);
Change Password of PS Document via C++
In the process of rendering PS to OTP, you can open a password protected PS and also change its password. In order to change the password of a PS file, you must know the owner password of that document. You can load password protected PDF document with Aspose.PDF for C++ by specifying its owner password and use ChangePasswords method to change the password.
// load an existing PS Document
auto doc = MakeObject<Document>(L"input.ps", L"owner");
// change password of PS Document
doc->ChangePasswords(L"owner", L"newuser", L"newuser");
// save the document
doc->Save(L"output.Doc");
Add Images From Web in OTP File via C++
After converting PS to OTP, you can also add images from web to your output document. Aspose.Slides for C++ supports operations with images in these popular formats: JPEG, PNG, BMP, GIF, and others. You can add one or several images on your computer onto a slide in a presentation. This sample code in C++ shows you how to add an image to a OTP file
// instantiate a Presentation object that represents a OTP file
auto pres = System::MakeObject<Presentation>("output.otp");
// get slide
auto slide = pres->get_Slides()->idx_get(0);
// initialize Web Client
auto webClient = System::MakeObject<WebClient>();
// get image data
auto imageData = webClient->DownloadData(System::MakeObject<Uri>(u"[REPLACE WITH URL]"));
// add image
auto image = pres->get_Images()->AddImage(imageData);
// add picture frame
slide->get_Shapes()->AddPictureFrame(ShapeType::Rectangle, 10.0f, 10.0f, 100.0f, 100.0f, image);
// save updated file
pres->Save(u"updated.otp", SaveFormat::Otp);

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.
