You can do this in Photoshop using the magic wand tool but you will
need the Geographic Imager plugin in order to preserve the spatial
information and retain the geotiff properties.<br>

type="cite">Hi,<br>
<br>
I have a geotiff file which is rectangular but the actual image is
irregular in shape and is surrounded on the outside by solid black.
Since I have no need to display the outside black part of the file I
would like to clip this out. I have already brought the geotiff file
in ArcMap and drawn the outline of the image that I want to keep to a
shape file. So I have the shape file and also the coordinates of that
shape of the image that I want to keep.
<br>
How can I clip out the image using either the shape file or the
coordinates as input to this geotiff?<br>
<br>
Thanks,<br clear="all">
