Closing a presentation document ?

[richardschoen]

There is no Close method to free up Presentation object. Even setting to null I get this error when I open a 2nd presentation.

Get following error when trying to add a new slide to 2nd instantiation:

Error in Operation Initializing slide at FileFormat.Words: Only one instance of the type is allowed for this parent. 
 Inner Exception: Cannot access part because parent package was closed. occurred while creating document c:\rjstemp\sample.pptx

The issue has been resolved. Here's an example to guide you moving forward:

            Presentation presentation = Presentation.Create("path_to_file.pptx");

            // Set slide dimensions
            presentation.SlideWidth = 960;
            presentation.SlideHeight = 720;

            // Define text shapes for the first slide
            TextShape titleShape = new TextShape
            {
                Text = "Title: Here is my first title From FF",
                TextColor = "980078",
                FontFamily = "Baguet Script"
            };

            TextShape bodyShape = new TextShape
            {
                Text = "Body: Here is my first body text From FF",
                FontFamily = "BIZ UDGothic",
                FontSize = 30,
                Y = Utility.EmuToPixels(2499619)
            };

            // Create slides and add shapes
            Slide slide1 = new Slide();
            slide1.AddTextShapes(titleShape);
            slide1.AddTextShapes(bodyShape);

            Slide slide2 = new Slide();
            slide2.AddTextShapes(titleShape);
            slide2.AddTextShapes(bodyShape);

            // Add slides to the presentation
            presentation.AppendSlide(slide1);
            presentation.AppendSlide(slide2);

            // Save and close the presentation
            presentation.Save();
            presentation.Close();

            // Instance 2: Create another presentation with text segments
            Presentation presentation2 = Presentation.Create("D:\\AsposeSampleResults\\test2.pptx");

            // Define title shape
            TextShape titleShape2 = new TextShape
            {
                Text = "Title: Here is my first title From FF",
                BackgroundColor = "5f7200",
                FontSize = 80,
                TextColor = "980078",
                FontFamily = "Baguet Script"
            };

            // Define body shape with text segments
            TextShape bodyShape2 = new TextShape
            {
                BackgroundColor = "ff7f90",
                Y = Utility.EmuToPixels(3499619)
            };

            List<TextSegment> textSegments = new List<TextSegment>
            {
                new TextSegment { Color = "980078", FontSize = 70, FontFamily = "Calibri", Text = "Body:" }.Create(),
                new TextSegment { Color = "000000", FontSize = 32, FontFamily = "Baguet Script", Text = " Here is my text segment" }.Create()
            };

            // Create a slide and add shapes and text segments
            Slide slide3 = new Slide();
            slide3.AddTextShapes(titleShape2);
            slide3.AddTextShapes(bodyShape2, textSegments);

            // Add slide to the presentation
            presentation2.AppendSlide(slide3);

            // Save and close the presentation
            presentation2.Save();
            presentation2.Close();
