Saving presentation with v15.6.0 of slides changes the font used for bullet points

using similar code as below, I open up the attached file on a remote server in a wcf service and return it.

Top 10 COBRA Mistakes and How to Avoid Them (Source).ppt

The result is the attached file:

Top 10 COBRA Mistakes and How to Avoid Them (Output).ppt

you should note that the original font, wingding code 168, used for the bullet points was changed during that saving process to normal text code 32. I also ran this locally in a test harness and on my local machine (see output.ppt) the original font for bullet points was changed to Wingdings 2 code 168, even though I have Wingdings available, so it behave different on different machines. the use of wingdings I think was due to the template used for the powerpoint.

the second issue I noted was that the last two slides in the source just have a single piece of text. if you look at the output, aspose slides added a bullet point to each of those single lines of text when it shouldn’t have.

let me know if you can reproduce these issues.

//inputFile is a byte array of the file

using (var output = new MemoryStream())


var document = Presentation(new MemoryStream(inputFile))

document.Save(output, SaveFormat.Ppt);

var fileOutput = output.ToArray()

// save off fileOutput to file or in our case return it from a wcf service
