NAME

       ale - a synthetic capture engine and renderer


SYNOPSIS

       ale [OPTIONS] original-frame [supplemental-frames ...] output-file

       ale [HELP OPTIONS]

       ale --version



DESCRIPTION

       ALE is a free software synthetic capture engine and renderer accepting,
       as input, a sequence of image frames, and producing, as output,
       rendered images, registration data, and 3D models (currently
       experimental).



EXAMPLES

       ale --hu
           Print the help page on program usage.

       ale 001.ppm 002.ppm 003.ppm out.ppm
           Render output file out.ppm from inputs 001.ppm, 002.ppm, and
           003.ppm.

       ale --scale 2 001.ppm 002.ppm 003.ppm out.png
           Render output file out.png at 2x scale.

       ale --perturb-upper=0 --trans-load=a.t --projective frame*.png out.png
           Render output file out.png from inputs frame*.png, using projective
           transformations as described in the file a.t.

       ale --3dv 0 out.png --projective frame*.png null:
           Render output file out.png from inputs frame*.png, using a 3D scene
           model to determine transformations.

       ale --visp last:sinc*lanc:6 sf:0 out/ .jpg in/*.jpg null:
           Render a video stream from files in/*.jpg to the directory out/,
           stabilizing to the first frame, with a lanczos-windowed sinc
           filter.


USAGE

       ale is a wrapper script that calls the executable ale-bin after
       extracting exposure EXIF information from image files (when the
       exiftool utility is available) and converting from raw formats (when
       the dcraw utility is available).

       When ale-bin has been linked with ImageMagick, input and output files
       may be of any kind supported by ImageMagick. Otherwise, only PPM files
       can be read and written by ale-bin.



OPTIONS

       OPTIONS are summarized via built-in help pages (see HELP OPTIONS
       below). More detailed manuals describing options and internal
       algorithms are available for certain versions of ALE. See SEE ALSO
       below for more details on other manuals.



HELP OPTIONS

       A listing of available help options can be obtained by invoking ale
       --hu.



ENVIRONMENT

       The wrapper script ale recognizes the following environment variables:

       ALE_BIN
           ALE executable to use.

       DCRAW
           dcraw raw extraction tool to use.

       EXIF_UTILITY
           EXIF extraction utility to use.


SEE ALSO

       More detailed manuals for certain versions of ALE are distributed with
       source packages, and may also be available from:
