Hi Guys<br><br>I'm reprojecting some rasters from OSGB (EPSG:27700) to WGS84 (EPSG:4326) and am running into a problem.<br><br>The rasters are reprojecting nicely, but I am left with black pixels around the image where the reprojected image doesnt fit squarely within the rectangular dimensions of the file.<br>
<br>I posted about this issue a few weeks ago, and then realised that I should be marking that colour as transparent when rendering using GeoServer, and ho! everything was OK.<br><br>However, I am now reprojecting some greyscale rasters, and by making the black pixels on the outside transparent, I am losing the black details of the raster image that I want to display!<br>
<br>Is there a way of selecting the colour that gdal uses to populate these dead pixels around the side?<br><br>MTIA<br><br>Rob<br>
