I’m not sure how to word what i am looking for so its been hard trying to find an answer. A friend recently installed photoshopCS3 and she asked me why her lines were choppy. So I looked at her file and sure enough it looked as though there was no anti-aliasing. So I’m no expert and the only plac I could find out about the anti-alias are the little check boxes under the selection tools. Is there something else that woul dmake this happen? it just shows the black line with no tranparent pixels on either sides etc…?

Thanks for any help… We are on WinXP and have PSCS3.

Well, this is a bit more complex. There’s a million ways to draw lines and curves and so is the various AA and blending options for them. The question would be, what lines we are talking about? Vector paths? Selections? Shapes? Paint brushes? Layer Styles? Most of these things will create properly smoothed/ antialiased output without the user having to do anything. Only things such as the shape drawing tools will require smoothing options to be enabled. The only other time when you should see no antialiasing is with brushes, that have no soft zones, like e.g. the square brushes used by the pencil tool. You will also get no antialaiasing on some drawing tools, when drawing perfectly perpendicular lines, that match the grid of the pixels, which is logical. Another case may be if you working in Index mode, where your colors are limited. Beyond that, I’m not really clear what your friend is experiencing. Having a screenshot or some more info about the tools used would certainly help.

Well, lets see the first time I saw a problem was when she opened up a PDF of mine that I created in PS, it looked like someone used a specialty brush to create it, but when I opened it it was just fine. Then she created a PSD, opened up a PDF of line art, then copied and paste it into the blank PSD. Now where ever there are curves there is no anti-alias or smoothing. But if I do the same it smooths? Its whacky. I’ll get my hands on her computer in the next couple days to get more details.

thanks for the response
