enblend --help
Usage: enblend [options] [--output=IMAGE] INPUT...
Blend INPUT images into a single IMAGE.

INPUT... are image filenames or response filenames.  Response
filenames start with an "@" character.

Common options:
  -V, --version          output version information and exit
  -a                     pre-assemble non-overlapping images
  -h, --help             print this help message and exit
  -l, --levels=LEVELS    limit number of blending LEVELS to use (1 to 29);
                         negative number of LEVELS decreases maximum;
                         "auto" restores the default automatic maximization
  -o, --output=FILE      write output to FILE; default: "a.tif"
  -v, --verbose[=LEVEL]  verbosely report progress; repeat to
                         increase verbosity or directly set to LEVEL
  -w, --wrap[=MODE]      wrap around image boundary, where MODE is "none",
                         "horizontal", "vertical", or "both"; default: none;
                         without argument the option selects horizontal wrapping
  -x                     checkpoint partial results
  --compression=COMPRESSION
                         set compression of output image to COMPRESSION,
                         where COMPRESSION is:
                         "deflate", "jpeg", "lzw", "none", "packbits", for TIFF files and
                         0 to 100, or "jpeg", "jpeg-arith" for JPEG files,
                         where "jpeg" and "jpeg-arith" accept a compression level
  --layer-selector=ALGORITHM
                         set the layer selector ALGORITHM;
                         default: "all-layers"; available algorithms are:
                         "all-layers": select all layers in all images;
                         "first-layer": select only first layer in each multi-layer image;
                         "largest-layer": select largest layer in each multi-layer image;
                         "no-layer": do not select any layer from any image;
  --parameter=KEY1[=VALUE1][:KEY2[=VALUE2][:...]]
                         set one or more KEY-VALUE pairs

Extended options:
  -c, --ciecam           use CIECAM02 to blend colors; disable with
                         "--no-ciecam"
  --fallback-profile=PROFILE-FILE
                         use the ICC profile from PROFILE-FILE instead of sRGB
  -d, --depth=DEPTH      set the number of bits per channel of the output
                         image, where DEPTH is "8", "16", "32", "r32", or "r64"
  -g                     associated-alpha hack for Gimp (before version 2)
                         and Cinepaint
  --gpu                  use graphics card to accelerate seam-line optimization
  -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

Mask generation options:
  --primary-seam-generator=ALGORITHM
                         use main seam finder ALGORITHM, where ALGORITHM is
                         "nearest-feature-transform" or "graph-cut";
                         default: "graph-cut"
  --image-difference=ALGORITHM[:LUMINANCE-WEIGHT[:CHROMINANCE-WEIGHT]]
                         use ALGORITHM for calculation of the difference image,
                         where ALGORITHM is "max-hue-luminance" or "delta-e";
                         LUMINANCE-WEIGHT and CHROMINANCE-WEIGHT define the weights
                         of lightness and color; default: delta-e:1: 1
  --coarse-mask[=FACTOR] shrink overlap regions by FACTOR to speedup mask
                         generation; this is the default; if omitted FACTOR
                         defaults to 8
  --fine-mask            generate mask at full image resolution; use e.g.
                         if overlap regions are very narrow
  --optimize             turn on mask optimization; this is the default
  --no-optimize          turn off mask optimization
  --optimizer-weights=DISTANCE-WEIGHT[:MISMATCH-WEIGHT]
                         set the optimizer's weigths for distance and mismatch;
                         default: 8:1
  --mask-vectorize=LENGTH
                         set LENGTH of single seam segment; append "%" for
                         relative value; defaults: 4 for coarse masks and
                         20 for fine masks
  --anneal=TAU[:DELTAE-MAX[:DELTAE-MIN[:K-MAX]]]
                         set annealing parameters of optimizer strategy 1;
                         defaults: 0.75:7000:5:32
  --dijkstra=RADIUS      set search RADIUS of optimizer strategy 2; default:
                         25 pixels
  --save-masks[=TEMPLATE]
                         save generated masks in TEMPLATE; default: "mask-%n.tif";
                         conversion chars: "%i": mask index, "%n": mask number,
                         "%p": full path, "%d": dirname, "%b": basename,
                         "%f": filename, "%e": extension; lowercase characters
                         refer to input images uppercase to the output image
  --load-masks[=TEMPLATE]
                         use existing masks in TEMPLATE instead of generating
                         them; same template characters as "--save-masks";
                         default: "mask-%n.tif"
  --visualize[=TEMPLATE] save results of optimizer in TEMPLATE; same template
                         characters as "--save-masks"; default: "vis-%n.tif"
Enblend accepts arguments to any option in uppercase as
well as in lowercase letters.
