ENBLEND(1)
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"
