=head1 DESCRIPTION

B<darktable> is a digital photography workflow application for B<Linux> 
and B<Mac OS X> in the lines of B<Adobe Lightroom> and B<Apple Aperture>.
It's described further in L<darktable(1)|darktable(1)>.

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

=head1 COMMAND LINE ARGUMENTS

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

=over

=item B<< <input file>  >>

The name of the input file to export.

=item B<< <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.

=item B<< <output file>  >>

The name of the output file. darktable derives the export file format
from the file extension.

=item B<< --width <max width>  >>

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

=item B<< --height <max height>  >>

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

=item B<< --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 B<FORMAT> is the name of the selected output format, for example B<png>.

=item B<< --hq <0|1|true|false>  >>

A flag that defines whether to use high quality resampling during
export. Defaults to true.

=item B<< --verbose  >>

Enables verbose output.

=item B<< --core <darktable options>  >>

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