       The gdal_translate utility can be used to convert raster data between different formats,
       potentially performing some operations like subsettings, resampling, and rescaling pixels
       in the process.

       -ot: type
           For the output bands to be of the indicated data type.

           Don't be forgiving of mismatches and lost data when translating to the output format.

       -of format:
           Select the output format. The default is GeoTIFF (GTiff). Use the short format name.

       -b band:
           Select an input band band for output. Bands are numbered from 1. Multiple -b switches
           may be used to select a set of input bands to write to the output file, or to reorder
           bands. Starting with GDAL 1.8.0, band can also be set to 'mask,1' (or just 'mask') to
           mean the mask band of the first band of the input dataset.

       -mask band:
           (GDAL >= 1.8.0) Select an input band band to create output dataset mask band. Bands
           are numbered from 1. band can be set to 'none' to avoid copying the global mask of the
           input dataset if it exists. Otherwise it is copied by default ('auto'), unless the
           mask is an alpha channel, or if it is explicitly used to be a regular band of the
           output dataset ('-b mask'). band can also be set to 'mask,1' (or just 'mask') to mean
           the mask band of the 1st band of the input dataset.

       -expand gray|rgb|rgba:
           (From GDAL 1.6.0) To expose a dataset with 1 band with a color table as a dataset with
           3 (RGB) or 4 (RGBA) bands. Useful for output drivers such as JPEG, JPEG2000, MrSID,
           ECW that don't support color indexed datasets. The 'gray' value (from GDAL 1.7.0)
           enables to expand a dataset with a color table that only contains gray levels to a
           gray indexed dataset.

       -outsize xsize[%] ysize[%]:
           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.

       -scale [src_min src_max [dst_min dst_max]]:
           Rescale the input pixels values from the range src_min to src_max to the range dst_min
           to dst_max. If omitted the output range is 0 to 255. If omitted the input range is
           automatically computed from the source data.

           Apply the scale/offset metadata for the bands to convert scaled values to unscaled
           values. It is also often necessary to reset the output datatype with the -ot switch.

       -srcwin xoff yoff xsize ysize:
           Selects a subwindow from the source image for copying based on pixel/line location.

       -projwin ulx uly lrx lry:
           Selects a subwindow from the source image for copying (like -srcwin) but with the
           corners given in georeferenced coordinates.

       -epo: (Error when Partially Outside)
           (GDAL >= 1.10) If this option is set, -srcwin or -projwin values that falls partially
           outside the source raster extent will be considered as an error. The default behaviour
           starting with GDAL 1.10 is to accept such requests, when they were considered as an
           error before.

       -eco: (Error when Completely Outside)
           (GDAL >= 1.10) Same as -epo, except that the criterion for erroring out is when the
           request falls completely outside the source raster extent.

       -a_srs srs_def:
           Override the projection for the output file. The srs_def may be any of the usual
           GDAL/OGR forms, complete WKT, PROJ.4, EPSG:n or a file containing the WKT.

       -a_ullr ulx uly lrx lry:
           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.

       -a_nodata value:
           Assign a specified nodata value to output bands. Starting with GDAL 1.8.0, can be set
           to none to avoid setting a nodata value to the output file if one exists for the
           source file

       -mo 'META-TAG=VALUE':
           Passes a metadata key and value to set on the output dataset if possible.

       -co 'NAME=VALUE':
           Passes a creation option to the output format driver. Multiple -co options may be
           listed. See format specific documentation for legal creation options for each format.

       -gcp pixel line easting northing elevation:
           Add the indicated ground control point to the output dataset. This option may be
           provided multiple times to provide a set of GCPs.

           Suppress progress monitor and other non-error output.

           Copy all subdatasets of this file to individual output files. Use with formats like
           HDF or OGDI that have subdatasets.

           (GDAL >= 1.8.0) Force (re)computation of statistics.

           The source dataset name. It can be either file name, URL of data source or subdataset
           name for multi-dataset files.

           The destination file name.


       gdal_translate -of GTiff -co "TILED=YES" utm.tif utm_tiled.tif

       Starting with GDAL 1.8.0, to create a JPEG-compressed TIFF with internal mask from a RGBA
       dataset :

       gdal_translate rgba.tif withmask.tif -b 1 -b 2 -b 3 -mask 4 -co COMPRESS=JPEG -co PHOTOMETRIC=YCBCR --config GDAL_TIFF_INTERNAL_MASK YES

       Starting with GDAL 1.8.0, to create a RGBA dataset from a RGB dataset with a mask :

       gdal_translate withmask.tif rgba.tif -b 1 -b 2 -b 3 -b mask
