Sorry I’ve been busy on another project, if you look at my post in this thread dated 09-21-2015, 9:24 AM you can see the chart title hilighted in yellow.
Looking at your screen shoot you are showing the original file and not the result file.
In the code I attached it does this:
Dim strpptFile As String
Dim strFile As String
Dim oPPTPres As Presentation
strpptFile = “C:\bin\ASPOSE Chart Title\Unnecessary Title.pptx”
strFile = “C:\bin\ASPOSE Chart Title\result.pptx”
oPPTPres = New Presentation(strpptFile)
oPPTPres.Save(strFile , Export.SaveFormat.Pptx)
The file result.pptx shows the issue.
