You can create or edit a PowerPoint file in ASP.NET MVC with Syncfusion PowerPoint library. The below are the steps.
Create a PowerPoint file in ASP.NET MVC
1.Create a new C# ASP.NET MVC application project.
2.Select the MVC template to create the project.
4.After installing the Syncfusion.Presentation.AspNet.Mvc5 nuget package, the following assemblies were included in our project.
5.The below code snippets demonstrate how to create a PowerPoint Presentation in ASP.NET MVC platform.
Create Presentation instance:
//Create a new instance of PowerPoint Presentation file IPresentation pptxDoc = Presentation.Create();
Add a new slide
//Add a new slide to file and apply background color ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.TitleOnly);
//Specify the fill type and fill color for the slide background slide.Background.Fill.FillType = FillType.Solid; slide.Background.Fill.SolidFill.Color = ColorObject.FromArgb(232, 241, 229);
Add title content:
//Add title content to the slide by accessing the title placeholder of the TitleOnly layout-slide IShape titleShape = slide.Shapes as IShape; titleShape.TextBody.AddParagraph("Company History").HorizontalAlignment = HorizontalAlignmentType.Center;
Add description content:
//Add description content to the slide by adding a new TextBox IShape descriptionShape = slide.AddTextBox(53.22, 141.73, 874.19, 77.70); descriptionShape.TextBody.Text = "IMN Solutions PVT LTD is the software company, established in 1987, by George Milton. The company has been listed as the trusted partner for many high-profile organizations since 1988 and got awards for quality products from reputed organizations.";
Add bullet points:
//Add bullet points to the slide IShape bulletPointsShape = slide.AddTextBox(53.22, 270, 437.90, 116.32); //Add a paragraph for a bullet point IParagraph firstPara = bulletPointsShape.TextBody.AddParagraph("The company acquired the MCY corporation for 20 billion dollars and became the top revenue maker for the year 2015."); //Format how the bullets should be displayed firstPara.ListFormat.Type = ListType.Bulleted; firstPara.LeftIndent = 35; firstPara.FirstLineIndent = -35; // Add another paragraph for the next bullet point IParagraph secondPara = bulletPointsShape.TextBody.AddParagraph("The company is participating in top open source projects in automation industry."); //Format how the bullets should be displayed secondPara.ListFormat.Type = ListType.Bulleted; secondPara.LeftIndent = 35; secondPara.FirstLineIndent = -35;
Add an image:
//Gets a picture as stream. FileStream pictureStream = new FileStream("Image.jpg", FileMode.Open); //Adds the picture to a slide by specifying its size and position. slide.Shapes.AddPicture(pictureStream, 499.79, 238.59, 364.54, 192.16);
You can download the image used in the sample from here.
Add a shape:
//Add an auto-shape to the slide IShape stampShape = slide.Shapes.AddShape(AutoShapeType.Explosion1, 48.93, 430.71, 104.13, 80.54); //Format the auto-shape color by setting the fill type and text stampShape.Fill.FillType = FillType.None; stampShape.TextBody.AddParagraph("IMN").HorizontalAlignment = HorizontalAlignmentType.Center;
Save and close the presentation:
//Save the PowerPoint Presentation pptxDoc.Save("Sample.pptx", FormatType.Pptx, HttpContext.ApplicationInstance.Response); //Close the PowerPoint presentation pptxDoc.Close();
The output of the above code example will generate the below PowerPoint slide.
Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion license key in your applications to use our components.
Read and edit a PowerPoint file in ASP.NET MVC
You can edit an existing PowerPoint file using this library. The below code snippet demonstrates accessing a shape from a slide and changing the text within it.
//Open an existing PowerPoint presentation IPresentation pptxDoc = Presentation.Open("Sample.pptx"); //Gets the first slide from the PowerPoint presentation ISlide slide = pptxDoc.Slides; //Gets the first shape of the slide IShape shape = slide.Shapes as IShape; //Change the text of the shape if(shape.TextBody.Text == "Company History") shape.TextBody.Text = "Company Profile"; //Save the PowerPoint presentation pptxDoc.Save("Output.pptx", FormatType.Pptx, HttpContext.ApplicationInstance.Response); //Close the PowerPoint presentation pptxDoc.Close();
