How smooth a raster edge

[JoséCarballo]

Hi, I wonder if there is any way to refine the edges of a raster when, i clip a raster the edges are like the teeth of a saw .
I would appreciate the help .

No.  Raster cells are square (for the most part).  Your options are

1 however produced, use a smaller cell size, it will just make the affect less noticable IF the edges are the result of a 

    process like interpolation

2 Mask it with a polylike overlay which is really really smooth (unlikely to get what you want) but some try

3  don't zoom in

4 convert the raster to polygon and use the simplify option  Raster to Polygon—Help | ArcGIS for Desktop

I wouldn't worry about it, everyone understands what raster edges are supposed to look like

thanks for the tips.
When I open the window of the spatial analysis, I clip the full imagen and I created a temporary file with smooth edges (attached pictures) but when I export the image the edge changes . My question is, with the raster polygon clip, there is no way to fill and cut the saw teeth with the polygon.

Thanks again

how did you export it? what properties did you specify? or did you not set your environment setting?

[JoséCarballo]

I didn`t set the enviroment settings. When i export the raster i didnt touch any value (atached imagen). there a way to export the image as it is as I see it before exporting ?
Thank you

well that 30x30 cell size is giving you the coarse jagged edge with the extent shown.  If the extent was much larger then the edge wouldn't be noticeable. 

I am of the feeling that if looks fine just the way it is.  In fact... hiding the edge may be suggesting erroneously that the resolution is finer given the shading pattern you have... hmmm... that's not what you want to do is it???

You could use a cubic convolution renderer (display tab of the raster properties).

That will fuzzy the edges somewhat.

Pixels are pixels. Generally square.

If you want to you could load this image into a mosaic dataset then edit the boundary so the saw tooth edge doesn't show.
