Quick Start Guide

A minimal console app and an ASP.NET Core endpoint that produce a .pptx end to end.

0Namespaces used by the C# samples

using NetCorePpt;                  // PptxGen, Slide
using NetCorePpt.CoreInterfaces;   // option objects: TextProps* / ShapeProps / ImageProps / TableProps / HAlign / VAlign ...
using NetCorePpt.CoreEnums;        // ShapeType, ChartType, MediaType, ShadowType, BulletType, DashType, SCHEME_COLORS ...
using TableRow = System.Collections.Generic.List<NetCorePpt.CoreInterfaces.TableCell>;

Create a PowerPoint in 4 easy steps

NetCorePpt PowerPoint presentations are created by following 4 basic steps. See examples below by environment.

That's really all there is to it!

.NET Application

The same four steps, in C# — a console app, a service, whatever you are building.

Program.cs

NetCorePpt · C#

using NetCorePpt;
using NetCorePpt.CoreInterfaces;

// 1. Create a new Presentation
var pres = new PptxGen();

// 2. Add a Slide
var slide = pres.addSlide();

// 3. Add one or more objects (Tables, Shapes, Images, Text and Media)
slide.addText("Hello World from NetCorePpt!", new TextPropsOptions
{
    x = 1,
    y = 1,
    color = "363636",
});

// 4. Save the Presentation
await pres.exportToFile("Hello-World.pptx");

Server-Side (ASP.NET Core)

Generation happens on the server, so an endpoint can hand the finished deck straight back to the caller — no browser download step.

Program.cs

NetCorePpt · C#

app.MapGet("/presentation", async () =>
{
    var pptx = new PptxGen();
    var slide = pptx.addSlide();
    slide.addText("Hello World from NetCorePpt!", new TextPropsOptions
    {
        x = 1,
        y = 1,
        color = "363636",
    });

    var bytes = await pptx.exportToBytes();
    return Results.File(bytes,
        "application/vnd.openxmlformats-officedocument.presentationml.presentation",
        "Hello-World.pptx");
});
