Free version

Download

To install GemBox.Presentation Free 2.1, enter your e-mail, download setup, and execute the .msi file.

Limitations

GemBox.Presentation Free delivers the same performance and set of features as the Professional version. However, the Free version is limited to five slides. This limitation is enforced during reading or writing files.

The ComponentInfo.FreeLimitReached event allows you to control what happens when your application reaches the free version limit. You can use this event to continue using the assembly in Trial mode for performance testing or to stop further reading/writing.

First steps

Using the GemBox.Presentation component is easy and straightforward. After referencing GemBox.Presentation.dll from your project, you can use the following code snippet to generate a simple PowerPoint file:

C# code

static void Main()
{
    // Set license key to use GemBox.Presentation in Free mode.
    ComponentInfo.SetLicense("FREE-LIMITED-KEY");

    // Create a new empty PowerPoint file.
    var presentation = new PresentationDocument();

    // Add a new empty slide.
    var slide = presentation.Slides.AddNew(SlideLayoutType.Custom);

    // Add a text box of size 5 x 5 cm in the top-left corner of the slide.
    var textBox = slide.Content.AddTextBox(0, 0, 5, 5, LengthUnit.Centimeter);

    // Add a paragraph with text content to the text box.
    textBox.AddParagraph().AddRun("Hello World!");

    // Save to PPTX and PDF files.
    presentation.Save("Presentation.pptx");
    presentation.Save("Presentation.pdf");
}

Visual Basic .NET code

Sub Main()
    ' Set license key to use GemBox.Presentation in Free mode.
    ComponentInfo.SetLicense("FREE-LIMITED-KEY")
    
    ' Create a new empty PowerPoint file.
    Dim presentation = New PresentationDocument()

    ' Add a new empty slide.
    Dim slide = presentation.Slides.AddNew(SlideLayoutType.Custom)

    ' Add a text box of size 5 x 5 cm in the top-left corner of the slide.
    Dim textBox = slide.Content.AddTextBox(0, 0, 5, 5, LengthUnit.Centimeter)

    ' Add a paragraph with text content to the text box.
    textBox.AddParagraph().AddRun("Hello World!")

    ' Save to PPTX and PDF files.
    presentation.Save("Presentation.pptx")
    presentation.Save("Presentation.pdf")
End Sub
