.SH NAME
enblend \- combine images using a multiresolution spline
.SH SYNOPSIS
.B enblend
[\fIoptions\fR] [\fI--output=IMAGE\fR] \fIINPUT\fR...
.SH DESCRIPTION
Blend INPUT images into a single IMAGE.
.PP
INPUT... are image filenames or response filenames.  Response
filenames start with an "@" character.
.SS "Common options:"
.TP
\fB\-V\fR, \fB\-\-version\fR
output version information and exit
.TP
\fB\-a\fR
pre\-assemble non\-overlapping images
.TP
\fB\-h\fR, \fB\-\-help\fR
print this help message and exit
.TP
\fB\-l\fR, \fB\-\-levels\fR=\fILEVELS\fR
number of blending LEVELS to use (1 to 29);
negative number of LEVELS decreases maximum
.TP
\fB\-o\fR, \fB\-\-output\fR=\fIFILE\fR
write output to FILE; default: "a.tif"
.TP
\fB\-v\fR, \fB\-\-verbose\fR[=\fILEVEL\fR]
verbosely report progress; repeat to
increase verbosity or directly set to LEVEL
.TP
\fB\-w\fR, \fB\-\-wrap\fR[=\fIMODE\fR]
wrap around image boundary, where MODE is
NONE, HORIZONTAL, VERTICAL, or BOTH; default: none;
without argument the option selects horizontal wrapping
.TP
\fB\-x\fR
checkpoint partial results
.TP
\fB\-\-compression\fR=\fICOMPRESSION\fR
set compression of output image to COMPRESSION,
where COMPRESSION is:
NONE, PACKBITS, LZW, DEFLATE for TIFF files and
0 to 100 for JPEG files
.SS "Extended options:"
.TP
\fB\-b\fR BLOCKSIZE
image cache BLOCKSIZE in kilobytes; default: 2048KB
.TP
\fB\-c\fR
use CIECAM02 to blend colors
.TP
\fB\-d\fR, \fB\-\-depth\fR=\fIDEPTH\fR
set the number of bits per channel of the output
image, where DEPTH is 8, 16, 32, r32, or r64
.TP
\fB\-g\fR
associated\-alpha hack for Gimp (before version 2)
and Cinepaint
.TP
\fB\-\-gpu\fR
use graphics card to accelerate seam\-line optimization
.TP
\fB\-f\fR 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
.TP
\fB\-m\fR CACHESIZE
set image CACHESIZE in megabytes; default: 1024MB
.SS "Mask generation options:"
.TP
\fB\-\-coarse\-mask\fR[=\fIFACTOR\fR] shrink overlap regions by FACTOR to speedup mask
generation; this is the default; if omitted FACTOR
defaults to 8
.TP
\fB\-\-fine\-mask\fR
generate mask at full image resolution; use e.g.
if overlap regions are very narrow
.TP
\fB\-\-smooth\-difference\fR=\fIRADIUS\fR
smooth the difference image prior to seam\-line
optimization with a Gaussian blur of RADIUS;
default: 0 pixels
.TP
\fB\-\-optimize\fR
turn on mask optimization; this is the default
.TP
\fB\-\-no\-optimize\fR
turn off mask optimization
.TP
\fB\-\-optimizer\-weights\fR=\fIDISTANCEWEIGHT[\fR:MISMATCHWEIGHT]
set the optimizer's weigths for distance and mismatch;
default: 8:1
.TP
\fB\-\-mask\-vectorize\fR=\fILENGTH\fR
set LENGTH of single seam segment; append "%" for
relative value; defaults: 4 for coarse masks and
20 for fine masks
.TP
\fB\-\-anneal\fR=\fITAU[\fR:DELTAEMAX[:DELTAEMIN[:KMAX]]]
set annealing parameters of optimizer strategy 1;
defaults: 0.75:7000:5:32
.TP
\fB\-\-dijkstra\fR=\fIRADIUS\fR
set search RADIUS of optimizer strategy 2; default:
25 pixels
.TP
\fB\-\-save\-masks\fR[=\fITEMPLATE\fR]
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
.TP
\fB\-\-load\-masks\fR[=\fITEMPLATE\fR]
use existing masks in TEMPLATE instead of generating
them; same template characters as "\-\-save\-masks";
default: "mask\-%n.tif"
.TP
\fB\-\-visualize\fR[=\fITEMPLATE\fR] save results of optimizer in TEMPLATE; same template
characters as "\-\-save\-masks"; default: "vis\-%n.tif"
