=head1 NAME
Image::Info::XBM - XBM support for Image::Info
=head1 SYNOPSIS
use Image::Info qw(image_info dim);
my $info = image_info("image.xbm");
if (my $error = $info->{error}) {
die "Can't parse image info: $error\n";
}
my $color = $info->{color_type};
my($w, $h) = dim($info);
=head1 DESCRIPTION
This modules supplies the standard key names
except for Compression, Gamma, Interlace, LastModificationTime, as well as:
=over
=item HotSpotX
The x-coord of the image's hotspot.
Set to -1 if there is no hotspot.
=item HotSpotY
The y-coord of the image's hotspot.
Set to -1 if there is no hotspot.
=item L1D_Histogram
Reference to an array representing a one dimensioanl luminance
histogram. This key is only present if C<image_info> is invoked
as C<image_info($file, L1D_Histogram=E<gt>1)>. The range is from 0 to 1.
=back
=head1 METHODS
=head2 process_file()
$info->process_file($source, $options);
Processes one file and sets the found info fields in the C<$info> object.
