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
  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
  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;
  set one or more KEY-VALUE pairs

    Extended options:

  image cache BLOCKSIZE in kilobytes; default: 2048KB
  force COLORSPACE for blending operations; Enblend uses "CIECAM" for images with ICC-profile and "IDENTITY" for those without and also for all floating-point images;
-c, --ciecam
  use CIECAM02 to blend colors; disable with "--no-ciecam"
  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
  manually set the size and position of the output image; useful for cropped and shifted input TIFF images, such as those produced by Nona
  set image CACHESIZE in megabytes; default: 1024MB

    Mask generation options:

  use main seam finder ALGORITHM, where ALGORITHM is "nearest-feature-transform" or "graph-cut"; default: "nearest-feature-transform"
  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
  generate mask at full image resolution; use e.g. if overlap regions are very narrow
  (deprecated) smooth the difference image prior to seam-line optimization with a Gaussian blur of RADIUS; default: 0 pixels
  turn on mask optimization; this is the default
  turn off mask optimization
  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
  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"
Enblend accepts arguments to any option in uppercase as well as in lowercase letters.


TMPDIR The TMPDIR environment variable points to the directory, where to store ImageCache files. If unset Enblend uses "/tmp".
