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.
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,
VERTICAL, 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
COMPRESSION 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 produced
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"; 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"
