NAME
       enblend - manual page for enblend 4.0-753b534c819d

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.

   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
	      number of blending LEVELS to use (1 to 29); negative  number  of
	      LEVELS decreases maximum

       -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, VER‐
	      TICAL,  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  COMPRES‐
	      SION  is:	 NONE,	PACKBITS, LZW, DEFLATE for TIFF files and 0 to
	      100 for JPEG files

   Extended options:
       -b BLOCKSIZE
	      image cache BLOCKSIZE in kilobytes; default: 2048KB

       -c     use CIECAM02 to blend colors

       -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  pro‐
	      duced by Nona

       -m CACHESIZE
	      set image CACHESIZE in megabytes; default: 1024MB

   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

       --smooth-difference=RADIUS
	      smooth the difference image prior to seam-line optimization with
	      a Gaussian blur of RADIUS; default: 0 pixels

       --optimize
	      turn on mask optimization; this is the default

       --no-optimize
	      turn off mask optimization

       --optimizer-weights=DISTANCEWEIGHT[:MISMATCHWEIGHT]
	      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[:DELTAEMAX[:DELTAEMIN[:KMAX]]]
	      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";  con‐
	      version  chars:  %i: mask index, %n: mask number, %p: full path,
	      %d: dirname, %b: basename, %f: filename, %e:  extension;	lower‐
	      case  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 tem‐
       plate
	      characters as "--save-masks"; default: "vis-%n.tif"
