Jagged Edges with Selections

[David Eichler]

Recently been seeing jagged edges in Photoshop with lines that should be perfectly straight. I am talking about selections made with the polygonal lasso.

Has something been changed in a recent update and I am missing a setting to correct this? I haven't made any changes in my workflow recently.

Makes no difference whether the anti-alias box is checked.

A little more info, please? At what zoom level are you seeing the jaggies? I tried the following as an experiment with the lasso tool: a diagonal box selection with no anti-alias filled with black on a blank layer, and one with anti-alias on another layer. If you do this and zoom to 800%, are you seeing something different from what I have here?

No, I don't have to go to that extreme a zoom to see it. I can even see it in a full-frame view in some cases, and it is readily apparent when zooming in to 50% or 100%. This is not a subtle thing.

Btw, doing straight-line selections with the Pen tool does not produce this effect.

That's because the pen tool creates vector objects. They never have jagged edges.

Possible fixes I would try: First, reset the tool. If that doesn't work, delete the Prefs file (save your settings before deleting it).

Thanks. A reset seems to have done the trick, though I have no idea why that should work. I can understand why trashing the preference file is a fix for a variety of issues.
