Index: The index of the slide.
FilePath: The name of the file to be exported and saved to disk. You can include
a full path; if you don't, Microsoft PowerPoint creates a file in the current
folder.
FilterName: The graphics format in which you want to export slides. The
specified graphics format must have an export filter registered in the Windows
registry. You can specify either the registered extension or the registered
filter name. Microsoft Office PowerPoint will first search for a matching
extension in the registry. If no extension that matches the specified string is
found, PowerPoint will look for a filter name that matches.
Width: The width in pixels of an exported slide.
Height: The height in pixels of an exported slide.
Example
The following java script shows how to export slide into jpg file.
function ExportSlide_Example ()
{
edoffice.SlideExportSlideToImage(1, "d:\1.jpg", "JPG");
}
Automating PowerPoint
Programmers can automate the Microsoft PowerPoint applications by using VBA, and when combined with VBScript, they have a very powerful tool at their disposal. The component provides two methods which return the Application and Presentation interface of the opened MS PowerPoint Presentation. The developers can add the following Key Code in the DocumentOpened event of the component.
For Example: KEY CODE in VB
Dim appPPT As PowerPoint.Application
Set appPPT = EDOffice1.GetApplication()
Dim oPre As PowerPoint.Presentation
Set oPre = EDOffice1.ActiveDocument()
Then the developers can do the PowerPoint automation without any difference.
