Unable to open dwf file using Image.Load()


We are using Aspose.CAD v 19.5.0 in evaluation mode to convert .DWF files to PDF with C#. At the moment we are unable to open attached “ACT3.dwf”, which we obtained from a sample source.
When using following code:
Image image = Image.Load(fileName);
leads to following exception depicted in ImageOpenException.png.

Appreciate if you could look in to this issue.

Thanks & regards,
