This is the command metapixel-prepare that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
metapixel - generator for photomosaics
metapixel-prepare [options] [srcdir] [destdir]
prepares the pictures in srcdir by creating resized images and a table
file in destdir
metapixel [options] [--metapixel input.jpg output.png --library destdir]
creates a photomosaic output.png using input.jpg as the input image and
destdir/tables.mxt as table file
This manual page documents briefly the metapixel and metapixel-prepare commands. For more
information check the README file included in the distribution.
metapixel is a program for generating photomosaics. It can generate classical
photomosaics, in which the source image is viewed as a matrix of equally sized rectangles
for each of which a matching image is substitued, as well as collage-style photomosaics,
in which rectangular parts of the source image at arbitrary positions (i.e. not aligned to
a matrix) are substituted by matching images.
metapixel-prepare is a utility that needs to be run before metapixel can be used. It
prepares your source images so that they can be used by metapixel to create the actual
metapixel-prepare srcdir destdir has to be run first. srcdir is the path to the directory
containing the source images, e.g. ~/Pictures/Holidays. destdir, e.g. ~/.metapixel, is the
path to the directory where you want to store the rescaled images and the tables.mxt index
file. This directory should be created manually before running metapixel-prepare.
metapixel --metapixel input.jpg output.png --library destdir is then used to transform an
image (input.jpg) into a mosaic (output.png) using the source images (described by
The options are described in the README file or by running metapixel or metapixel-prepare
with the --help option.
