| Jan 4, 2013 at 8:55 | comment | added | Tomek | Just draw bounding rectangle in feature class and Clip in ArcGIS or in ArcGIS with Spatial Analyst - Extract by Attributes (if raster is reclassyfied) or Mask or Polygon or Rectangle. A lots of possibilities. | |
| Jan 4, 2013 at 8:42 | comment | added | blah238 | I replaced your sample with a 8-bit version with color map and alpha channel for NoData. Spatial Analyst doesn't work that well with multi-band rasters, and your white background is actually 254/255/255. | |

added an example

| Jan 4, 2013 at 0:55 | comment | added | blah238 | By "minimum bounding extent" are you looking for a rectangular extent or a polygonal footprint representing the area of the image with data? | |
| Jan 4, 2013 at 0:54 | comment | added | blah238 | "I would like to delete the null rows and columns for this raster." What exactly does this mean? I don't understand what the desired end result is. | |
