The default is GeoTIFF (GTiff). Use the short format name. </dd><dt><b>-b</b> <em>band</em>:</dt><dd>Select an input band <em>band</em> for output. Bands are numbered from 1 Multiple <b>-b</b> switches may be used to select a set of input bands to write to the output file, or to reorder bands. </dd><dt><b>-outsize</b> <em>xsize[%] ysize[%]</em>:</dt><dd>Set the size of the output file. Outsize is in pixels and lines unless '' is attached in which case it is as a fraction of the input image size. </dd><dt><b>-scale</b> <em>[src_min src_max [dst_min dst_max]]</em>:</dt><dd>Rescale the input pixels values from the range <em>src_min</em> to <em>src_max</em> to the range <em>dst_min</em> to <em>dst_max</em>.

The <em>srs_def</em> may be any of the usual GDAL/OGR forms, complete WKT, PROJ.4, EPSG:n or a file containing the WKT. </dd><dt><b>-a_ullr</b> <em>ulx uly lrx lry</em>:</dt><dd>Assign/override the georeferenced bounds of the output file. This assigns georeferenced bounds to the output file, ignoring what would have been derived from the source file. </dd><dt><b>-a_nodata</b> <em>value</em>:</dt><dd>Assign a specified nodata value to output bands. </dd><dt><b>-mo</b> <em>"META-TAG=VALUE"</em>:</dt><dd>Passes a metadata key and value to set on the output dataset if possible. </dd><dt><b>-co</b> <em>"NAME=VALUE"</em>:</dt><dd>Passes a creation option to the output format driver.
