Various kinds of shapes like triangle, rectangle, ellipse, star, line and etc, can be created with Spire.Presentation. To make shapes more compatible with the entire slide, not only can we set color and choose fill style of the shape, we can also rotate shapes to a desired degree. This article is aimed to provide a simple example.
To begin with, create or open a .NET class application in Visual Studio 2005 or above versions, add Spire.Presentation.dll to your .NET project assemblies. Then, you are able create and format shapes using the sample C# code we have offered below.
Code snippets for rotate shapes on slide:
Step 1: Create an instance of Presentation class.
Presentation presentation = new Presentation();
Step 2: Add a new shape - Triangle ,to PPT slide.
IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Triangle, new RectangleF(100, 100, 100, 100));
Step 3: Rotate the shape to 180 degree.
shape.Rotation = 180;
Step 4: Set the color and fill style of shape.
shape.Fill.FillType = FillFormatType.Solid; shape.Fill.SolidColor.Color = Color.BlueViolet; shape.ShapeStyle.LineColor.Color = Color.Black;
Step 5: Save and launch the file.
presentation.SaveToFile("shape.pptx", FileFormat.Pptx2010);
System.Diagnostics.Process.Start("shape.pptx");

IAutoShape shape = presentation.Slides[0].Shapes.AppendShape(ShapeType.Triangle, new RectangleF(100, 100, 100, 100));
//set rotation to 180
shape.Rotation = 180;
//set the color and fill style of shape
shape.Fill.FillType = FillFormatType.Solid;
shape.Fill.SolidColor.Color = Color.BlueViolet;
shape.ShapeStyle.LineColor.Color = Color.Black;
//save the document
presentation.SaveToFile("shape.pptx", FileFormat.Pptx2010);
