Adobe Photoshop CS4 - smooth rough edges?  Illustrator a better choice?

I have attached a PSD file generated by Adobe PS CS4.

If you zoom in, the edges of the black area are not smooth.  I want the edges to be smooth no matter how much I zoom.

I guess what I really want is vector images?

This may be better in Illustrator, but I don't know what to do.

You can use Illustrator or Photoshop, it is a matter of preference. The ability to zoom without ever becoming pixelated comes from being vector art. Photoshop is better with raster (but it also has vector capabilities). The pen tool and shape tools are vector, if you make a square and try to paint it, it will tell you it must be rasterized (now it is no longer vector).

If you don't understand all of that, the simple answer is Illustrator is the preferred method to work with vector art. If you save the document as a jpeg, png, gif, it will become rasterized and not be zoomable without pixelation. The available formats to remain vector are .ai (adobe illustrator format), .eps (encapsuled postscript file), .pdf (portable document format). If you have any questions please ask them and I will try to help.

If you have Adobe Illustrator CS4, you can open the PSD in Illustrator and perform a live trace on the object which will automatically make it vector by tracing the shape. You will have to play with the settings to achieve the optimal results, but this can save you some time. I will upload the results of you file. i used the live trace, and then expanded it. After the expand, I used the smooth tool in the pencil toolbar to fix some of the rough edges. The PDF can be opened in Illustrator and edited.
