Manipulate Presentation via .NET API

The open source ShapeCrawler library allows software developers to process PowerPoint PPTX presentations without having Microsoft Office installed. The library simplifies the process of accessing PowerPoint files with just a couple of lines of .NET code. Software Developers can open an existing presentation, iterate through its slides, insert images into a slide, get text holder auto shape, auto-fit text, add and update hyperlink, interact with individual shapes and many more. The following example shows how software developers can handle images in presentation inside .NET applications.

using var pres = SCPresentation.Open("picture.pptx");

// get picture shape
var picture = pres.Slides[0].Shapes.GetByName("Picture 1");

// change image
picture.Image.SetImage("new-image.png");

// get MIME type of image, eg. "image/png"
var mimeType = picture.Image.MIME;

pres.Save();

Work with Images & Charts in Presentation

The open source ShapeCrawler library has provided complete support for working with images and charts inside presentations. Handling images and multimedia elements within presentations becomes a streamlined process with library. The library is designed to work with various versions of PowerPoint, making it a versatile choice for .NETs developers. The library facilitates tasks like, inserting new images, replacing existing images, adjusting images properties, or even extracting them for external use. Here is an example that demonstrates how software developers can update properties of a Chart inside presentation using .NET API.

using var pres = SCPresentation.Open("helloWorld.pptx");
var slide = pres.Slides.First();

// get chart
var chart = (IChart)slide.Shapes.First(sp => sp is IChart);

// print chart title
if (chart.HasTitle)
{
    Console.WriteLine(chart.Title);
}

if (chart.Type == SCChartType.BarChart)
{
    Console.WriteLine("Chart type is BarChart");
}

// update category
chart.Categories[0].Name = "Price";

Manage Text & Extract Data from Presentation via .NET

ShapeCrawler library allows users to easily modify the properties of shapes and text within PowerPoint slides via .NET API. Whether you need to update text content, change the position of shapes, or manipulate their attributes, this library provides a straightforward API to make these changes. One of the most valuable use cases of ShapeCrawler library is extracting data from presentation. The library has provided very powerful features for managing text and other relevant data inside PowerPoint presentation via .NET API. Software developers can programmatically extract data from PowerPoint presentations, making it an excellent tool for generating reports or transforming presentation content into other formats, such as Excel or PDF. The following example shows how to replace text in the first slide of the presentations.

using var pres = SCPresentation.Open("some.pptx");
var textFrames = pres.Slides[0].GetAllTextFrames();

foreach (var textFrame in textFrames)
{
    textFrame.Text = "some text";
}

pres.Save();
