This is happened when I have a circular shape (marquee tool selection). THen after that I converted to Work Path (by right click of that selection). And I add 2.0 as its Tolerance Pixel.
After applying it. The shape become not perfect, could you see the difference? I make it with a black background so everyone could see it from the image no.2.
I realized this is a problem, because If i use that path for placing a text. the text wont follow the correct path as circular (selection), instead ... the shape a bit changed (i think it's ugly shape :: see the detail of the arrow).
How to solve this case ? I'm using Photoshop CS3.
