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.Ppsm
presentation.Save("output.ppsm", SaveFormat.Ppsm);
Get XMP Metadata from MHTML File via .NET
While converting MHTML to PPSM, 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 PPSM 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 PPSM file to Read-Only, which means users (after they open the presentation) see the Read-Only recommendation.
Presentation presentation = new Presentation("PptxOutput.pptx");
// make PPSM read only
presentation.ProtectionManager.ReadOnlyRecommended = true;
// call save method while passing SaveFormat.Ppsm
presentation.Save("output.ppsm", SaveFormat.Ppsm);
