Get XMP Metadata from CGM File via .NET
While converting CGM to OTP, 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 CGM file’s XMP metadata. To get a CGM file’s metadata, you can create a Document object and open the input CGM file. After that, you can get the file’s metadata using the Metadata property.
Document doc = new Document("input.cgm");
// get CGM XMP properties
Console.WriteLine(doc.Metadata["xmp:CreateDate"]);
Console.WriteLine(doc.Metadata["xmp:Nickname"]);
Console.WriteLine(doc.Metadata["xmp:CustomProperty"]);
Create Read Only OTP 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 OTP file to Read-Only, which means users (after they open the presentation) see the Read-Only recommendation.
Presentation presentation = new Presentation("PptxOutput.pptx");
// make OTP read only
presentation.ProtectionManager.ReadOnlyRecommended = true;
// call save method while passing SaveFormat.Otp
presentation.Save("output.otp", SaveFormat.Otp);
