<div dir="ltr"><div>Hi Andrea:<br><br>I think you can use raster calculator and divide your clipped raster by a mask raster. The mask raster has 1 value inside your area of interest and 0 value outside, so:<br><br>INSIDE: non 0 value / 1 = non 0 value; and 0 / 1 = 0<br>
<br>OUTSIDE: 0 or non 0 value / 0 = ¿null?<br><br>Greetings<br><br>Carlos Cerdán<br></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">2014-07-02 8:25 GMT-05:00 Andrea Acinelli <span dir="ltr"><<a href="mailto:aacinelli@gmail.com" target="_blank">aacinelli@gmail.com</a>></span>:<br>

I'm working with a grayscale georeferenced and clipped raster (.tif). The raster has been clipped with the 'clipper' tool using a shapefile as a mask. The resulting raster has black bands of color along the four edges which can be turned off by assigning 0 pixel values to NO DATA values in the transparency tab of the raster properties. The problem I have is that many other pixels within the clipped area have 0 value which are also turned off. How can I obtain a final raster that has 0 values only outside the clipped area?<br>
