makexvpics - create xv-compatible thumbnails
makexvpics [ -fhRv ] picture_file_or_dir [ ... ]
Makexvpics creates/updates xv/zgv/Gimp-compatible thumbnails for
picture files such as GIFs, JPEGs, etc. It may be useful if you want a
non-interactive way of keeping such files up to date.
The formats currently supported are GIF, JPEG, PNG, PBM/PGM/PPM, mrf,
BMP, TGA, and PCX.
-f force thumbnails to be updated. Ordinarily they’re only updated
if no thumbnail exists or if the picture file is newer.
-h give usage help.
-R recurse into subdirectories.
-v be verbose - echo names (or rather, ‘basename’s) of files which
are being updated.
It’s pretty slow.
