       enblend - combine images using a multiresolution spline


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


       Blend INPUT images into a single IMAGE.

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


   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

              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

   Advanced options:
              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              will be withdrawn in favor of "--blend-colorspace"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"

              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

              generate mask at full image resolution; use  e.g.   if  overlap  regions  are  very

              turn on mask optimization; this is the default; disable with "--no-optimize"

              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

              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

              use the ICC profile from PROFILE-FILE instead of sRGB

              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;

              set one or more KEY-VALUE pairs

   Expert mask generation options:
              use  main  seam finder ALGORITHM, where ALGORITHM is "nearest-feature-transform" or
              "graph-cut"; default: "graph-cut"

              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

              set the optimizer's weigths for distance and mismatch; default: 8:1

              set LENGTH of single seam segment; append "%" for relative value; defaults:  4  for
              coarse masks and 20 for fine masks

              set annealing parameters of optimizer strategy 1; defaults: 0.75:7000:5:32

              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 all globbing algorithms

              show all recognized image formats and their filename extensions

              show who compiled the binary when and on which machine

              show the software components with which Enblend was compiled

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


              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.

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