AppendPicture Issue

AppendPicture Issue

I am adding a couple pictures to a word document via docx. When I add the pictures to the document and create it they all come out in the correct orientation. 

If I do the same thing, but user the ConvertToPdf option the some of the photos are rotated 90 degrees. I have not been able to figure out why. 

Has anyone seen this? Is there a way to do the CreatePicture() without having to put a float number so that it put in the full picture size?

Xceed.Document.NET.Image image1 = doc.AddImage(a.PImage);
                    Picture picture1 = image1.CreatePicture(600f,500f);
                    par51.AppendPicture(picture1);
