I’m trying to change widht of a canvas. I’m changing 720 to 920, and whole %$^@^* layer is resizing. I do have every option in Lock and Links selected. How to do that properly, no nothing from my work be transformed?
as for the locks and links, this should do fine
i wouldn’t dare to touch the rest, though. Not without any backup 
And a bit of additional details
Just realized this while looking at them again
Pixel aspect, width, and height would do almost the same, with a few differences
Pixel Width - Keeps the width
Pixel Height - Keeps the Height
Pixel Aspect - Keeps them both
