Description
Antialiasing Command in View Menu allows improving image quality displaying in Source Display Frame and in Target Display Frame especially when it is with low resolution or when user is operating a zoom. In particular, it reduces the saw-shaped border of elements that made up the image. When this option is activated, it'll appear a chack sign on the left side near the item in the View Menu.
How to find it
You can find it in View Menu in Main Window.
