Render MHTML to SWF within C++ Applications
Convert MHTML to SWF within your C++ Applications without using Microsoft® PowerPoint
Why to Convert MHTML to SWF?
If you are a C++ developer looking to add a feature to your applications that allows for the conversion of MHTML to SWF, then you have come to the right place. MHTML is a web page archive format that is used to store web pages and their associated resources. SWF is a vector-based file format used for multimedia, vector graphics, and ActionScript. Converting MHTML to SWF can be useful for creating interactive multimedia presentations, animations, and other interactive content.
How Aspose.Total Helps for MHTML to SWF Conversion?
Aspose.Total for C++ is a comprehensive suite of APIs that can help you with your MHTML to SWF conversion needs. It includes two APIs, Aspose.PDF for C++ and Aspose.Slides for C++, which can be used to export MHTML to PPTX and then convert PPTX to SWF. To export MHTML to PPTX, you can use Aspose.PDF for C++. This API allows you to convert MHTML to PPTX with just a few lines of code. Once you have the PPTX file, you can use Aspose.Slides for C++ to convert it to SWF. This API provides a wide range of features that can help you create high-quality SWF files from PPTX. With Aspose.Total for C++, you can easily and quickly convert MHTML to SWF.
C++ API to Export MHTML to SWF
- Open MHTML file using Document class reference
- Convert MHTML 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 MHTML file with an instance of Document class
auto doc = MakeObject<Document>(u"template.mhtml");
// save MHTML 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 MHTML Document via C++
In the process of rendering MHTML to SWF, you can open a password protected MHTML and also change its password. In order to change the password of a MHTML 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 MHTML Document
auto doc = MakeObject<Document>(L"input.mhtml", L"owner");
// change password of MHTML 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 MHTML 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);
