==== enfuse, version 3.2 ====
Usage: enfuse [options] -o OUTPUT INPUT...
Fuse INPUT images into a single OUTPUT image.

Common options:
  -h                     Print this help message
  -l LEVELS              Number of blending levels to use (1 to 29)
  -o FILENAME            Write output to FILENAME
  -v                     Verbosely report progress; repeat to
                           increase verbosity
  -w                     Blend across -180/+180 degrees boundary
  --compression=COMP     Set compression of output image to COMP,
                           where COMP is:
                             NONE, PACKBITS, LZW, DEFLATE (for TIFF files)
                             0-100 (for JPEG files)
 -z                     Use LZW compression (TIFF only).
                          Kept for backward compatability with older scripts

Extended options:
  -b BLOCKSIZE           Image cache BLOCKSIZE in Kilobytes.  Default: 2048KB
  -c                     Use CIECAM02 to blend colors
  -g                     Associated-alpha hack for Gimp (before version 2)
                           and Cinepaint
  -f WIDTHxHEIGHT[+xXOFFSET+yYOFFSET]
                         Manually set the size and position of the output
                           image.  Useful for cropped and shifted input
                           TIFF images, such as those produced by Nona.
  -m CACHESIZE           Images CACHESIZE in Megabytes.  Default: 1024MB

Fusion options:
  --wExposure=WEIGHT     Weight given to well-exposed pixels
                           (0 <= WEIGHT <= 1).  Default: 1
  --wSaturation=WEIGHT   Weight given to highly-saturated pixels
                           (0 <= WEIGHT <= 1).  Default: 0.2
  --wContrast=WEIGHT     Weight given to high-contrast pixels
                           (0 <= WEIGHT <= 1).  Default: 0
  --wMu=MEAN             Center aka MEAN of Gaussian weighting
                           function (0 <= MEAN <= 1).  Default: 0.5
  --wSigma=SIGMA         Standard deviation of Gaussian weighting
                           function (SIGMA > 0).  Default: 0.2
  --HardMask             Force hard blend masks and no averaging on finest
                           scale.  This is especially useful for focus
                           stacks with thin and high contrast features,
                           but leads to increased noise.

Expert options:
  --ContrastWindowSize=SIZE
                         Window SIZE for local-contrast analysis.
                           (SIZE >= 3).  Default: 5
  --GrayProjector=OPERATOR
                         Apply grayscale projection OPERATOR, where
                           OPERATOR is one of "average", "l-star",
                           "lightness", "value", "luminance", or
                           "channel-mixer:RED-WEIGHT:GREEN-WEIGHT:BLUE-WEIGHT".
                           Default: "average"
  --EdgeScale=EDGESCALE[:LCESCALE[:LCEFACTOR]]
                         Scale on which to look for edges.  Positive
                           LCESCALE switches on local contrast enhancement
                           by LCEFACTOR (EDGESCALE, LCESCALE, LCEFACTOR >= 0).
                           Append "%" to LCESCALE for values relative to
                           EDGESCALE; append "%" to LCEFACTOR for relative
                           value.  Defaults: 0:0:0
  --MinCurvature=CURVATURE
                         Minimum CURVATURE for an edge to qualify.  Append
                           "%" for relative values.  Default: 0.
  --debug                Output mask images for debugging
