{
    image.DateTimeStamp = testTime;
    image.AuthorName = "John Smith";
    image.AuthorComments = "Comment";
    image.ImageId = "ImageId";
    image.JobNameOrId = "Important Job";
    image.JobTime = TimeSpan.FromDays(10);
    image.TransparentColor = Color.FromArgb(123);
    image.SoftwareId = "SoftwareId";
    image.SoftwareVersion = "abc1";
    image.SoftwareVersionLetter = 'a';
    image.SoftwareVersionNumber = 2;
    image.XOrigin = 1000;
    image.YOrigin = 1000;

    image.Save("test.tga")
}
