Render MHTML to POTM via .NET
.NET API to Export MHTML to POTM on Windows, macOS, and Linux without using Microsoft® PowerPoint
Aspose.Total for .NET is a powerful package of File Format Automation APIs that enables you to easily render MHTML to POTM in two simple steps. The first step involves using the PDF Processing API, Aspose.PDF for .NET, to transform the MHTML file format into PPTX. This API provides a wide range of features that allow you to manipulate PDF documents in various ways, such as creating, editing, converting, and merging PDFs.
The second step involves using the Presentation Processing API, Aspose.Slides for .NET, to convert the PPTX to POTM. This API provides a comprehensive set of features that enable you to create, edit, and convert presentations in various formats, such as PPT, PPTX, POT, POTX, PPS, PPSX, and PPTM. It also allows you to manipulate slides, shapes, text, and images in presentations.
By using Aspose.Total for .NET, you can quickly and easily render MHTML to POTM in two simple steps. The PDF Processing API, Aspose.PDF for .NET, is used to transform the MHTML file format into PPTX, and the Presentation Processing API, Aspose.Slides for .NET, is used to convert the PPTX to POTM. Both APIs provide a wide range of features that enable you to manipulate documents and presentations in various ways.
.NET API to Convert MHTML to POTM
- Open MHTML file using Document class
- Convert MHTML to PPTX by using Save method
- Load PPTX file by using Presentation class
- Save the document to POTM format using
Save
method and set
Potmas SaveFormat
Get Started with .NET File Format APIs
Install from command line as nuget install Aspose.Total or via Package Manager Console of Visual Studio with Install-Package Aspose.Total.
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
Document document = new Document("input.mhtml");
// save MHTML as a PPTX
document.Save("PptxOutput.pptx", SaveFormat.Pptx);
// load PPTX with an instance of Presentation
Presentation presentation = new Presentation("PptxOutput.pptx");
// call save method while passing SaveFormat.Potm
presentation.Save("output.potm", SaveFormat.Potm);
Get XMP Metadata from MHTML File via .NET
While converting MHTML to POTM, you might need extra XMP metadata information to prioritize your batch conversion process. For example you can get and sort your conversion documents based on creation date and process the documents accordingly. Aspose.PDF for .NET allows you to access a MHTML file’s XMP metadata. To get a MHTML file’s metadata, you can create a Document object and open the input MHTML file. After that, you can get the file’s metadata using the Metadata property.
Document doc = new Document("input.mhtml");
// get MHTML XMP properties
Console.WriteLine(doc.Metadata["xmp:CreateDate"]);
Console.WriteLine(doc.Metadata["xmp:Nickname"]);
Console.WriteLine(doc.Metadata["xmp:CustomProperty"]);
Create Read Only POTM File via .NET
By using Aspose.Slides for .NET API, you can further enhance the features of your conversion application. One of the feature can be to create your output file read only to increase security. The API allows you to set your POTM file to Read-Only, which means users (after they open the presentation) see the Read-Only recommendation.
Presentation presentation = new Presentation("PptxOutput.pptx");
// make POTM read only
presentation.ProtectionManager.ReadOnlyRecommended = true;
// call save method while passing SaveFormat.Potm
presentation.Save("output.potm", SaveFormat.Potm);
