[gdal-dev] Translating files with a external mask file

[Travis Kirstine]

I have a rgb geotiff with a external mask file
rgb_withmaskfile.tif.msk, I would like to convert the files to a
compressed GeoTiff using a command simalar to the one below.  This
command will generate a illegal band # error

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