Anisotropic vs Bicubic Sampling

[Blushock]

For the move tool, what is the difference between these two modes? I found no difference between image qualities when resizing with them.

Bicubic tends to produces a shaper result, Anisotropic a smoother one. You'll see a bigger difference if you take a large image and make it much smaller (like 25% of its original size), and then toggle between the two.

Speaking of which, when anisotropic sampling was introduced, I used to get it mixed up with bilinear sampling, as I couldn’t tell the difference between the two (it’s still pretty hard to tell the difference to me).

 

What differences do they have?

Bilinear Sampling? Is that for a different tool?

Not sure abt the difference between sharpness and smoothness without going into circular definitions. Still, this is good info, and thank you for it. I can always just mess with each image's move tool setting and see if I notice a difference.

Move tool.....

.....and also image Resize

Oh I see I see. But in terms of those two, is one better than the other? I'd assume move is best for specific layers whilst image resize is for the entire canvas.
