Core.ProfilePictureUploader questions

In the code, I can see it's using Microsoft.SharePoint.Client.File.SaveBinaryDirect to upload Picture to SharePoint Online. Is there a function I can call to Remove a Profile Picture instead?

                    using (Stream mediumThumb = ResizeImageSmall(ProfilePicture, _mediumThumbWidth))
                    {
                        if (mediumThumb != null)
                        {
                            spImageUrl = string.Format(spPhotoPathTempate, PictureName, "M");
                            LogMessage("Uploading medium image to " + spImageUrl, LogLevel.Information);
                            Microsoft.SharePoint.Client.File.SaveBinaryDirect(mySiteclientContext, spImageUrl, mediumThumb, true);

                        }
                    }
