SYNOPSIS

9       enblend [options] [--output=IMAGE] INPUT...
10

DESCRIPTION

12       Blend INPUT images into a single IMAGE.
13
14       INPUT... are image filenames or response filenames.  Response filenames
15       start with an "@" character.
16
17   Common options:
18       -V, --version
19              output version information and exit
20
21       -a     pre-assemble non-overlapping images
22
23       -h, --help
24              print this help message and exit
25
26       -l, --levels=LEVELS
27              number of blending LEVELS to use (1 to 29); negative  number  of
28              LEVELS decreases maximum
29
30       -o, --output=FILE
31              write output to FILE; default: "a.tif"
32
33       -v, --verbose[=LEVEL]
34              verbosely  report  progress;  repeat  to  increase  verbosity or
35              directly set to LEVEL
36
37       -w, --wrap[=MODE]
38              wrap around image boundary, where MODE is NONE, HORIZONTAL, VER‐
39              TICAL,  or  BOTH;  default:  none;  without  argument the option
40              selects horizontal wrapping
41
42       -x     checkpoint partial results
43
44       --compression=COMPRESSION
45              set compression of output image to COMPRESSION,  where  COMPRES‐
46              SION  is:  NONE,  PACKBITS, LZW, DEFLATE for TIFF files and 0 to
47              100 for JPEG files
48
49   Extended options:
50       -b BLOCKSIZE
51              image cache BLOCKSIZE in kilobytes; default: 2048KB
52
53       -c     use CIECAM02 to blend colors
54
55       -d, --depth=DEPTH
56              set the number of bits per channel of the  output  image,  where
57              DEPTH is 8, 16, 32, r32, or r64
58
59       -g     associated-alpha hack for Gimp (before version 2) and Cinepaint
60
61       --gpu  use graphics card to accelerate seam-line optimization
62
63       -f WIDTHxHEIGHT[+xXOFFSET+yYOFFSET]
64              manually  set  the size and position of the output image; useful
65              for cropped and shifted input TIFF images, such  as  those  pro‐
66              duced by Nona
67
68       -m CACHESIZE
69              set image CACHESIZE in megabytes; default: 1024MB
70
71   Mask generation options:
72       --coarse-mask[=FACTOR] shrink overlap regions by FACTOR to speedup mask
73              generation; this is the default; if omitted FACTOR defaults to 8
74
75       --fine-mask
76              generate  mask  at  full  image resolution; use e.g.  if overlap
77              regions are very narrow
78
79       --smooth-difference=RADIUS
80              smooth the difference image prior to seam-line optimization with
81              a Gaussian blur of RADIUS; default: 0 pixels
82
83       --optimize
84              turn on mask optimization; this is the default
85
86       --no-optimize
87              turn off mask optimization
88
89       --optimizer-weights=DISTANCEWEIGHT[:MISMATCHWEIGHT]
90              set  the optimizer's weigths for distance and mismatch; default:
91              8:1
92
93       --mask-vectorize=LENGTH
94              set LENGTH of single  seam  segment;  append  "%"  for  relative
95              value; defaults: 4 for coarse masks and 20 for fine masks
96
97       --anneal=TAU[:DELTAEMAX[:DELTAEMIN[:KMAX]]]
98              set  annealing  parameters  of  optimizer  strategy 1; defaults:
99              0.75:7000:5:32
100
101       --dijkstra=RADIUS
102              set search RADIUS of optimizer strategy 2; default: 25 pixels
103
104       --save-masks[=TEMPLATE]
105              save generated masks in TEMPLATE; default:  "mask-%n.tif";  con‐
106              version  chars:  %i: mask index, %n: mask number, %p: full path,
107              %d: dirname, %b: basename, %f: filename, %e:  extension;  lower‐
108              case  characters  refer  to input images uppercase to the output
109              image
110
111       --load-masks[=TEMPLATE]
112              use existing masks in TEMPLATE instead of generating them;  same
113              template characters as "--save-masks"; default: "mask-%n.tif"
114
115       --visualize[=TEMPLATE] save results of optimizer in TEMPLATE; same tem‐
116       plate
117              characters as "--save-masks"; default: "vis-%n.tif"
