The F file will always be created in I. The thumbnails will be saved in F<.thumbs>, also in I. If I is not specified, the current directory is used. Note that only the images in the directory itself will be processed, recursion is not supported. =head1 OPTIONS =over =item B<-x>, B<--archive> Create (and link) an "image.tar" archive containing all full-size image files. All but the last directories in the files' path are stripped, besides that the directory structure is preserved. So, if you run gen-xhtml-thumbnails -x in .../mydir/, the archive will contain mydir/1.jpg, mydir/2.jpg etc. =item B<-c>, B<--css> I Use I for css definitions =item B<-n>, B<--no-names> Do not show image names below thumbnails =item B<-d>, B<--size> I Maximum thumbnail size (either width or height). Defaults to 200 =item B<-s>, B<--spacing> I Use I as spacing factor. The size of each image element (image + possible border around it) is the number of pixels (see --size) times I. So for B<1.1> you have a small border around each image, for B<1.0> you have no border at all, etc. =item B<-t>, B<--title> I Use I<title> as <title> for the XHTML output =item B<-q>, B<--quality> I<int> Set thumbnail quality. Accepts values between 0 and 100, where 100 is the highest possible quality =back =head1 EXIT STATUS Zero upon success, non-zero otherwise. =head1 CONFIGURATION None. =head1 DEPENDENCIES B<gen-xhtml-thumbnails> requires the Image::Imlib2 perl module. =head1 BUGS AND LIMITATIONS There is no detection for changed images, the thumbnails of deleted images are not removed. =head1 AUTHOR Copyright (C) 2009, 2010 by Daniel Friesel E<gt>derf@chaosdorf.deE<lt> =head1 LICENSE 0.
