For VB.NET developers who want to convert PowerPoint document to other image or document formats through VB.NET programming, you may use our PowerPoint Converting SDK for VB.NET. This page will give you an overview of converting PowerPoint document in VB.NET applications. There are some basic questions on PowerPoint conversion in VB.NET.
  • To conduct PowerPoint conversion in VB.NET, what APIs will be used?
  • What is the definition of each class in the APIs for converting PowerPoint (.pptx) in VB.NET?
  • What are supported images or documents to which source PowerPoint document can be converted in VB.NET?
APIs for PPT Converting in VB.NET
With APIs given below, developers will find it easier to compile specific .NET program to convert PowerPoint document to certain image or document format using VB language. From the APIs, you can see that the source PowerPoint document is rendered to REImage at first and then the rendered REImage is converted to specific image or document file. To get a REImage collection, you may need to load your PowerPoint containing all slides from native file or stream. Then you can select specific slide(s) to be rendered.
' Render PowerPoint document slide to REImage.
Private Function GetPage(pageIndex As Integer) As BasePage Implements PPTXDocument.GetPage
End Function
Private Function toImage() As BaseImage Implements PPTXPage.toImage
End Function
Private Function toImage(height As Integer, width As Integer) As BaseImage Implements PPTXPage.toImage
End Function

' Convert the REImage to certain image format.
Private Sub SaveImageFile(image As REImage, filePath As [String]) Implements REFile.SaveImageFile
End Sub
Definition of Each Class
There are three main classes in the APIs for converting PowerPoint (.pptx) document to other image or document formats in VB.NET programming: PPTXDocument, PPTXPage and REImage. Specifically speaking, PPTXDocument is an object used to represent the source PowerPoint document in the programming level. It contains PowerPoint documentation features and all PPT slides. PPTXPage can be regarded as an abstraction of a PowerPoint slide in VB.NET program. Finally, REImage is an image object defined by RasterEdge document imaging products.
Note: Our VB.NET PowerPoint Document Converting Library only empowers developers to convert PPT document with ".pptx" suffix in VB.NET applications. Please check your PowerPoint document version before using .NET this library.
