It just show's it that way when you zoom it in. Look at 100%. And it is vector. Enlarge image up to 300% (for example) and check it out at 100% zoom - everything is fine. Just don't zoom it in, that's not work smooth for PS. But it still vector shape and will be fine if you print it or something.
Everything is okey is your PS. PS is about raster and real world image. And that's mean pixels per inch (or cm, whatever). When you zoom in you see those pixels. Shape itself theoreticly is vector object and it is. You can resize it, transform it and it won't get blury. But as it is raster image at the end so PS shows it "rendered" and it is build of real pixels. Ilustrator is mathematic representation of image and there you can zoom in as much as it allows and you will not see any pixels. That's just how it works.
I'm not so good at theoretic, i'm practical. When it comes to explain it get's even worse. Maybe someone can explain it smoother.
But as resume - it is okey, nothing else is posible in PS. Use Illustrator if it bother you.
Yes. When I change to 'fill pixels' I get the anti-alias box, but it doesn't change the smoothness of the shapes whether I check it or un-check it. I'm attaching another screen shot that shows the rough edges better. Notice the ruler at the top (in inches). Is this amount of pixelation normal for PhotoShop? Thanks
Great. I'm coming to PhotoShop from Illustrator, so I'm not used to seeing the rough edges. I just wanted to know that there wasn't anything else I could do to smooth the edges in PhotoShop.
