       Options:

           --width <max width>
           --height <max height>
           --bpp <bpp>
           --hq <0|1|true|false>
           --upscale <0|1|true|false>

DESCRIPTION

       darktable is a digital photography workflow application for Linux, Mac OS X and several
       other Unices.  It's described further in darktable(1).

       darktable-cli is a command line variant to be used to export images given the raw file and
       the accompanying xmp file.

OPTIONS

       The user needs to supply an input filename and an output filename.  All other parameters
       are optional.

       <input file>
           The name of the input file to export.

       <xmp file>
           The optional name of an XMP sidecar file containing the history stack data to be
           applied during export.  If this option is not given darktable will search for an XMP
           file that belongs to the given input file.

       <output file>
           The name of the output file.  darktable derives the export file format from the file
           extension.  You can also use all the variables available in darktable's export module
           in the output filename.

       --width <max width>
           This optional parameter allows one to limit the width of the exported image to that
           number of pixels.

       --height <max height>
           This optional parameter allows one to limit the height of the exported image to that
           number of pixels.

       --bpp <bpp>
           An optional parameter to define the bit depth of the exported image; allowed values
           depend on the file format.  Currently this option is not yet functional.  If you need
           to define the bit depth you need to use the following workaround:

               --core --conf plugins/imageio/format/<FORMAT>/bpp=<VALUE>

           where FORMAT is the name of the selected output format, for example png.

       --hq <0|1|true|false>
           A flag that defines whether to use high quality resampling during export.  Defaults to
           true.

       --upscale <0|1|true|false>
           A flag that defines whether to allow upscaling during export.  Defaults to false.

       --verbose
           Enables verbose output.

       --core <darktable options>
           All command line parameters following --core are passed to the darktable core and
           handled as standard parameters.  See darktable(1) for a detailed description of the
           options.
