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, 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"
