Aspose.Slides

It’s not uncommon that developers need to extract the text from a presentation. To do so, you need to extract text from all the shapes on all the slides in a presentation. This article explains how to extract text from Microsoft PowerPoint PPTX presentations using Aspose.Slides. Whether extracting text from one slide or an entire presentation, Aspose.Slides uses the PresentationScanner Class and the static methods it exposes. They are all packed under the namespace Aspose.Slides.Util.


 string FilePath = @"..\..\..\..\Sample Files\";

string FileName = FilePath + "Move a Paragraph from One Presentation to Another 1.pptx";

string DestFileName = FilePath + "Move a Paragraph from One Presentation to Another 2.pptx";

MoveParagraphToPresentation(FileName, DestFileName);

// Moves a paragraph range in a TextBody shape in the source document

// to another TextBody shape in the target document.

public static void MoveParagraphToPresentation(string sourceFile, string targetFile)

{

    string Text = "";

    //Instantiate Presentation class that represents PPTX//Instantiate Presentation class that represents PPTX

    Presentation sourcePres = new Presentation(sourceFile);

    //Access first shape in first slide

    IShape shp = sourcePres.Slides[0].Shapes[0];

    if (shp.Placeholder != null)

    {

        //Get text from placeholder

        Text = ((IAutoShape)shp).TextFrame.Text;

        ((IAutoShape)shp).TextFrame.Text = "";

    }

    Presentation destPres = new Presentation(targetFile);

    //Access first shape in first slide

    IShape destshp = sourcePres.Slides[0].Shapes[0];

    if (destshp.Placeholder != null)

    {

        //Get text from placeholder

        ((IAutoShape)destshp).TextFrame.Text += Text;

    }

    sourcePres.Save(sourceFile, Aspose.Slides.Export.SaveFormat.Pptx);

    destPres.Save(targetFile, Aspose.Slides.Export.SaveFormat.Pptx);

}

}
