// AV: this loader is used in the RotateTask because when using the partial read loader the rotation is not applied (I don't know why). I tried to dig into the iText code but it
// looks like a treasure map to me, I can't follow it and I'm not able to find why rotation is not working. As a workaround we use this loader in the RotateTask that seems
// working.
