Examples

The following example shows how to convert the first slide to the framed image with the RenderToGraphics method.

[C#]
using (Presentation pres = new Presentation("Presentation.pptx"))
{
    Size slideSize = new Size(1820, 1040);
    // Creates a Bitmap with the specified size (slide size + fields)
    using (Bitmap slideImage = new Bitmap(slideSize.Width + 50, slideSize.Height + 50))
    {
        using (Graphics graphics = Graphics.FromImage(slideImage))
        {
            // Fills and translates Graphics to create a frame around the slide
            graphics.Clear(Color.Red);
            graphics.TranslateTransform(25f, 25f);
            // Renders the first slide to Graphics
            pres.Slides[0].RenderToGraphics(new RenderingOptions(), graphics, slideSize);
        }
        // Saves the image in the JPEG format
        slideImage.Save("FramedSlide_0.jpg", ImageFormat.Jpeg);
    }
}

The following example shows how to conversion process for a slide with notes using the RenderToGraphics.

[C#]
using (Presentation pres = new Presentation("PresentationNotes.pptx"))
{
    // Gets the presentation notes size
    Size notesSize = pres.NotesSize.Size.ToSize();
    // Creates the rendering options
    IRenderingOptions options = new RenderingOptions();
    // Sets the position of the notes
    options.NotesCommentsLayouting.NotesPosition = NotesPositions.BottomTruncated;
    // Creates a Bitmap with the notes' size
    using (Bitmap slideImage = new Bitmap(notesSize.Width, notesSize.Height))
    {
        // Renders the first slide to Graphics
        using (Graphics graphics = Graphics.FromImage(slideImage))
        {
            pres.Slides[0].RenderToGraphics(options, graphics, notesSize);
        }
        // Saves the image in PNG format
        slideImage.Save("Slide_Notes_0.png", ImageFormat.Png);
    }
}
