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.
*ALE_COUNT_THREADS*::
Displays statistics on thread counts when set to a non-zero value.
*PAGER*::
Text pager to use (e.g., for displaying help pages).

packages, and may also be available from:
