Turning off antialiasing in Photoshop!?

it can, go to options for each tool, there is a checkbox for it, there is not one switch to turn it off for every tool though....

I've tried it, but the broblem is - if you want to paste an image to a magic pink background, when you flatten it - it will change the color around the image edges and it won't be transparent and the pink will become visible!
Heeelp!

Thats because the image you're pasting has anti aliased edges...

flatten it and attack those naughty pixels manually.

Buby, what yo ca try is to paste it on a separate layer, use the magic wand tool with antialiasing turned off, click outside of your image to select everything around it, expand your selection by one or two pixels (in the select menu), then press delete. Depending on your image it might work. Otherwise, the longer way is to use the lasso to cut off the antialising.

Thanks, everyone!! I'll go and try it right away!
