ale [HELP OPTIONS]
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

ale 001.ppm 002.ppm 003.ppm out.ppm
Render output file out.ppm from inputs 001.ppm, 002.ppm, and
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
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 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.
A listing of available help options can be obtained by invoking ale
The wrapper script ale recognizes the following environment variables:
ALE executable to use.
dcraw raw extraction tool to use.
EXIF extraction utility to use.
Displays statistics on thread counts when set to a non-zero value.
Text pager to use (e.g., for displaying help pages).
More detailed manuals for certain versions of ALE are distributed with
source packages, and may also be available from:
