OLE Object

This article demonstrates embedding a file as an OLE object and updating its data using Aspose.Slides for .NET.

Add an OLE Object

Embed a PDF file into the presentation.

static void AddOleObject()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var pdfData = File.ReadAllBytes("doc.pdf");
    var dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
    var oleFrame = slide.Shapes.AddOleObjectFrame(20, 20, 50, 50, dataInfo);
}

Access an OLE Object

Retrieve the first OLE object frame on a slide.

static void AccessOleObject()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var pdfData = File.ReadAllBytes("doc.pdf");
    var dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
    var oleFrame = slide.Shapes.AddOleObjectFrame(20, 20, 50, 50, dataInfo);

    var firstOleFrame = slide.Shapes.OfType<IOleObjectFrame>().First();
}

Remove an OLE Object

Delete an embedded OLE object from the slide.

static void RemoveOleObject()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var pdfData = File.ReadAllBytes("doc.pdf");
    var dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
    var oleFrame = slide.Shapes.AddOleObjectFrame(20, 20, 50, 50, dataInfo);

    slide.Shapes.Remove(oleFrame);
}

Update OLE Object Data

Replace the data embedded in an existing OLE object.

static void UpdateOleObjectData()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var pdfData = File.ReadAllBytes("doc.pdf");
    var dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
    var oleFrame = slide.Shapes.AddOleObjectFrame(20, 20, 50, 50, dataInfo);

    var newData = File.ReadAllBytes("Picture.png");
    var newDataInfo = new OleEmbeddedDataInfo(newData, "png");
    oleFrame.SetEmbeddedData(newDataInfo);
}
