GemBox.Presentation Free Version

Limitations

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

C# VB.NET

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 slide with a text box of size 5 x 5 cm in the top-left corner.
    presentation.Slides.AddNew(SlideLayoutType.Custom)
        .Content.AddTextBox(0, 0, 5, 5, LengthUnit.Centimeter)
        .AddParagraph()
        .AddRun("Hello World!");

    // Save to PPTX file.
    presentation.Save("Presentation.pptx");
}

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 slide with a text box of size 5 x 5 cm in the top-left corner.
    presentation.Slides.AddNew(SlideLayoutType.Custom) _
        .Content.AddTextBox(0, 0, 5, 5, LengthUnit.Centimeter) _
        .AddParagraph() _
        .AddRun("Hello World!")

    ' Save to PPTX file.
    presentation.Save("Presentation.pptx")
End Sub
