Magnetic Lasso Tool - Jagged Edges

[abcdefg]

Sometimes when I use the magnetic lasso tool to select a part of an image I get jagged edges even with anit-aliased turned off.

Any ideas on how to stop this?

well if it's not anti-aliasing (and remember you need to turn it on/off before you actually use the magic wand), it could be that you filled using the bucket tool, in wich case it will produce jagged edged...

Although it seems your selection was used to cut out, so that's weird...

yea... use the pen tool :P

Things like the tragic wand and the lasso tool are good tools to get a rough start on something but they require some post editing afterwards, because they aren't exact. What I would do at this point is mask off the jaggedness.

Try feathering the active selection for 2-3 pixels. or play around with the lasso's sensitivity (edge contrast) .

The pen tool is crap IMO :lol:

I guess I will try that. How to I mask off the jaggedness?

@ Ditto: I tryed both things you suggested, doesn't seem to help. :/

Exactly what is the edge contrast? I'm guessing the smoothness of the edges?

Thanks for all the comments.

Ok so this pen tool is kinda gangsta but it's tricky. There has to be an option I am missing with the lasso tool to get rid of those jagged edges. It's so much faster to use.

As you get used to the pen tool it won't take as long.

I personally hate the lasso tool. I'd rather take the eraser tool and erase the content manually than use that crap lasso.

have you tried the pologonal lasso tool?

I've had some success with the extract filter, though it does typically require a little clean-up also.

im not sure what it is but i love the pen in AI and HATE it in PS. It must be the same thing but it seems like it is so much more diffucult to use the pen in PS. Is there a difference? you would think Adobe would use the same code.

Bro I couldn't agree more. Although after playing around with it for the past 2 hours it's not as bad as I thought.

can try going to "layer" then to "matte" then to "defringe" and play there once you try the above and if you dont want to use the pen tool :P

[3d Nirvana]

is the actuall picture like that when u save it out? It could be ur zoom settings are weird, i get jaggies whenever I'm not at 25, 50, 75, or 100 percent zoom.

[mlkedave]

well it looks like the background was white, correct?

If it was, a you can double click the layer to bring up the Blending Modes window, and than use the 'Blend If:' slider. Just move the top right slider towards the left. You will see the white disappear.

If this earses some of the white in the image itself, copy the orignal layer (without the Blend If: slider adjustments), and put it above the modified layer. Than put a 'Hide All' mask, and paint in the areas accidently earsed.

Hope it helps.

Omfg instead of doing it all over again just take the smudge / blur tool and go over those jaggies!

But yeah, the pen tool would have been a better option.


BTW guys, the lasso tool works great only if you set the frequency to 100... then there arent that many noticable jaggies.

Most people don't do that... it increases the # of points the magnetic lasso creates.
