After instantiating and using the PdfConverter, whenever, I call the close method, my application hangs. I've waited upto 4 minutes before killing the process. I noticed that none of your examples call the close method. Close is supposed to release resources used by the converter before disposing of the object. Does this method work:?
Dim converter As PdfConverter = New PdfConverter()
Dim prefix As String = "D:\Test\"
Dim suffix As String = ".png"
Dim imageCount As Integer = 1
converter.GetNextImage(prefix + imageCount + suffix, ImageFormat.Png)
imageCount = imageCount + 1
