On first image yow can see an icon, a line is selected in Adobe Illustrator.
On second image you can see the image after
Save for Web .. was pressed.
I do not need anti-aliasing, extra strip between gray and black spaces. How can I turn off anti-aliasing in
I am now confused, it seems that pictures are not anti-aliased, but
Preview anti-aliase it.
But if I check it with magnifier, I can see that it it not aliased.
Save for Web .. has a setting too, that has an effect on anti aliasing
