FelisShape

FelisShape is a .NET library for manipulating the presentations which conform to the Office Open XML File Formats specification. It is a platform-independent library base on the Open XML SDK.

Installation

dotnet add package FelisShape

Namespace

The basic namespace is FelisOpenXml.FelisShape. Some class may be contained in sub-namespace such as FelisOpenXml.FelisShape.Draw and so on.

Basic Usage

Presentation

Load a presentation from a stream:

var pres = new FelisPresentaion(soureceStream);

Create a empty presentation taken an other one as the template:

var template = new FelisPresentaion(templateStream);
var target = FelisPresentation.From(template);

Save a presentation:

// pres is an instance of FelisPresentation
pres.Save(targetStream);	// save to a stream
pres.Save("filePath.pptx");	// save to a file

Slide

Enumerating the slides in a presentation

// pres is an instance of FelisPresentation
foreach (var slide in pres.Slides)
{
	// TODO: ...
}

Insert a duplicate of a slide into a presentation

pres.InsertSlide(sourceSlide, indexForInsertingAt);

Remove a slide in a presentation

slide.Remove();
// or
pres.RemoveSlide(slide);

Edit a customer data in a slide

slide.WorkWithCustomerData("nameOfTheData", (XmlDocument dataDoc) =>
{
	// TODO: ...
	return true; // Return true means there is some changings should be commited to the slide. Otherwise return false.
}, true);
// The last argument of WorkWithCustomerData means if a new customer data should be created when there is no existing one.
// The default value is false.

Remove a customer data in a slide

slide.RemoveCustomerData("nameOfTheData");

Sumbit any changings in the slide

slide.Submit();
// Notice: Without invoking this method, the changings in the slide may be lost after close the presentation.

Shapes

Enumerating the shapes in a slide

foreach (var shape in slide.Shapes)
{
	// TODO: ...
}

Get a shape by a given ID in a slide or in a shapes group

slideOrGroup.GetShapeById(id);

Get a shape with a special type a slide or in a shapes group

slideOrGroup.GetShapes<T>();
// The T can be one of follows:
//		FelisShape
//		FelisPicture 
//		FelisTable 
//		FelisChart
//		FelisConnectionShape
//		FelisOleObject
//		FelisShapeGroup

Manipulating the data of the shape

The id of the shape

Console.WriteLine(shape.Id);
shape.Id = newId;

The name of the shape

Console.WriteLine(shape.Name);
shape.Name = newName;

The rect of the shape

var rect = shape.Rect;
shape.Rect = new FelisShapeRect() { x = 0, y = 0, cx = 100, cy = 100 };

The rect of the shape, the coordinate is relative to the parent shape

var ret = shape.RelativeRect;
shape.RelativeRect = new FelisShapeRect() { x = 0, y = 0, cx = 100, cy = 100 };

The text in the shape

Console.WriteLine(shape.TextBody?.Text);
shape.TextBody.Text = "Hello world";

The fill of the shape

var fill = new FelisSolidFillValue();
fill.Color.Value = Color.FromArgb(255, 0, 0);
shape.Fill = fill;
