ale - a synthetic capture engine and renderer

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).

       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).

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

       ale001.ppm002.ppm003.ppmout.ppm
           Render output file out.ppm from inputs 001.ppm, 002.ppm, and 003.ppm.

       ale--scale2001.ppm002.ppm003.ppmout.png
           Render output file out.png at 2x scale.

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

       ale--3dv0out.png--projectiveframe*.pngnull:
           Render output file out.png from inputs frame*.png, using a 3D scene model to determine
           transformations.

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

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

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

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

       ale--version

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.
