NAME

       enblend - combine images using a multiresolution spline

SYNOPSIS

       enblend [options] [--output=IMAGE] INPUT...

DESCRIPTION

       Blend INPUT images into a single IMAGE.

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

OPTIONS

   Common options:
       -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

       --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

   Advanced options:
       --blend-colorspace=COLORSPACE
              force COLORSPACE for blending operations; Enblend uses  "CIELUV"  for  images  with
              ICC-profile  and  "IDENTITY"  for  those  without  and  also for all floating-point
              images; other available blend color spaces are "CIELAB" and "CIECAM"

       -c, --ciecam
              use CIECAM02 to blend colors; disable with "--no-ciecam";  note  that  this  option
              will be withdrawn in favor of "--blend-colorspace"

       -d, --depth=DEPTH
              set  the  number of bits per channel of the output image, where DEPTH is "8", "16",
              "32", "r32", or "r64"

       -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

       -g     associated-alpha hack for Gimp (before version 2) and Cinepaint

       -w, --wrap[=MODE]
              wrap  around  image  boundary,  where  MODE is "none", "horizontal", "vertical", or
              "both"; default: none; without argument the option selects horizontal wrapping

   Mask generation options:
       --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; disable with "--no-optimize"

       --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"

   Expert options:
       -a, --pre-assemble
              pre-assemble non-overlapping images; negate with "--no-pre-assemble"

       -x     checkpoint partial results

       --fallback-profile=PROFILE-FILE
              use the ICC profile from PROFILE-FILE instead of sRGB

       --layer-selector=ALGORITHM
              set  the layer selector ALGORITHM; default: "all-layers"; available algorithms are:
              "all-layers": select all layers in any  image;  "first-layer":  select  only  first
              layer  in  each  (multi-)layer  image; "last-layer": select only last 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

   Expert 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

       --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

   Information options:
       -h, --help
              print this help message and exit

       -V, --version
              output version information and exit

       --show-globbing-algorithms
              show all globbing algorithms

       --show-image-formats
              show all recognized image formats and their filename extensions

       --show-signature
              show who compiled the binary when and on which machine

       --show-software-components
              show the software components with which Enblend was compiled

       Enblend accepts arguments to any option in uppercase as well as in lowercase letters.

ENVIRONMENT

       OMP_NUM_THREADS
              The  OMP_NUM_THREADS  environment  variable  sets  the  number of threads to use in
              OpenMP parallel regions.  If unset Enblend uses as many threads as there are CPUs.

       OMP_DYNAMIC
              The OMP_DYNAMIC environment variable controls dynamic adjustment of the  number  of
              threads to use in executing OpenMP parallel regions.
