I understand Ar saves an image as PTG,so if I try to import say jpeg or any other will AR convert the image or do I ? If I have to convert the image then how and where is it done,or, is this not a valid question and not to be of any concern. I know PTG stores a lot of information,more then other files will. That being said, exporting should be my next question. Do I need to convert the ptg so that it can be seen in mail,or by my printer or by a professional printer?
