Render PS to SWF within C++ Applications
Convert PS to SWF within your C++ Applications without using Microsoft® PowerPoint
Are you a C++ developer looking to add to integrate PS to SWF 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 SWF. Both APIs come under Aspose.Total for C++ package.
C++ API to Export PS to SWF
- 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 SWF format using
Save
member function and set
Swfas 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 Swf format
prs->Save(u"output.swf", Aspose::Slides::Export::SaveFormat::Swf);
Change Password of PS Document via C++
In the process of rendering PS to SWF, 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 SWF File via C++
After converting PS to SWF, 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 SWF file
// instantiate a Presentation object that represents a SWF file
auto pres = System::MakeObject<Presentation>("output.swf");
// 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.swf", SaveFormat::Swf);

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 SWF File Format?
The SWF (Shockwave Flash) file format is a popular multimedia format primarily used for delivering interactive and animated content on the web. Developed by Macromedia (now owned by Adobe Systems), SWF files are widely supported by web browsers and plug-ins, making them an integral part of web design and online entertainment.
SWF files are primarily composed of vector graphics, animation, audio, and video elements. They are created using software such as Adobe Animate (formerly known as Flash Professional) or other SWF authoring tools. The format supports interactivity through scripting languages like ActionScript, allowing developers to create interactive buttons, menus, and games within SWF files.
One of the key advantages of SWF files is their compact size. They are highly compressed, resulting in small file sizes that can be quickly downloaded and streamed over the internet. This makes SWF files ideal for delivering multimedia content efficiently, even on slower internet connections.
SWF files are often embedded into web pages, providing a seamless and engaging user experience. They can be played directly within web browsers using Adobe Flash Player or other SWF players. Additionally, SWF files can be standalone applications or screensavers, providing versatile usage beyond the web.
Over the years, the SWF format has evolved to support advanced features like 3D graphics, hardware acceleration, and multimedia streaming. However, it’s important to note that the usage of SWF files has declined in recent years due to the rise of alternative web technologies, such as HTML5 and CSS3, which offer similar capabilities without the need for additional plug-ins or proprietary software.
