I was a bit disappointed when I found out that in flash CS4 Adobe did not fixed (yet) the accuracy of the 9 slice (aka 9 scale) nor the accuracy of any guide line. In most reasonable software one would guess that there will be an option to type the coordinates of guidelines (9slice is a case of a general guide line as I see it). But not in flash …
Why would this accuracy so important? Well usually it doesn’t and if you zoom in to 2k and make it more or less on a round pixel – it will be fine. However – If you have tried to make an accurate flex component skin – any glitch might grow within flex and this really needs an accurate placement.
So – what’s my solution? Grid!
If you turn on the grid and make the flash snap to it – all guidelines (including 9slice) will also be snapped to the grid. If you work in “blind man zoom” as I do (sometime) you could define the grid to 1 pixel width and height and your guides would snap only to round pixels.
PS. This snapping thing does not work if you use “snap to pixel”.
