ENBLEND(1) User Commands ENBLEND(1) NAME enblend - manual page for enblend 4.2 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. OPTIONS Common options: -l, --levels=LEVELS limit number of blending LEVELS to use (1 to 29); negative number of LEVELS decreases maximum; "auto" restores the default automatic max- imization -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 --compression=COMPRESSION set compression of output image to COMPRESSION, where COMPRESSION is: "deflate", "jpeg", "lzw", "none", "packbits", for TIFF files and 0 to 100, or "jpeg", "jpeg-arith" for JPEG files, where "jpeg" and "jpeg-arith" accept a compression level Advanced options: --blend-colorspace=COLORSPACE force COLORSPACE for blending operations; Enblend uses "CIELUV" for images with ICC-profile and "IDENTITY" for those without and also for all floating-point images; other available blend color spaces are "CIELAB" and "CIECAM" -c, --ciecam use CIECAM02 to blend colors; disable with "--no-ciecam"; note that this option will be withdrawn in favor of "--blend-colorspace" -d, --depth=DEPTH set the number of bits per channel of the output image, where DEPTH is "8", "16", "32", "r32", or "r64" -f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 -g associated-alpha hack for Gimp (before version 2) and Cinepaint -w, --wrap[=MODE] wrap around image boundary, where MODE is "none", "horizontal", "vertical", or "both"; default: none; without argument the option selects horizontal wrapping 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 --optimize turn on mask optimization; this is the default; disable with "--no-optimize" --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 tem- plate 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" Expert options: -a, --pre-assemble pre-assemble non-overlapping images; negate with "--no-pre-assemble" -x checkpoint partial results --fallback-profile=PROFILE-FILE use the ICC profile from PROFILE-FILE instead of sRGB --layer-selector=ALGORITHM set the layer selector ALGORITHM; default: "all-layers"; available algorithms are: "all-layers": select all layers in any image; "first-layer": select only first layer in each (multi-)layer image; "last-layer": select only last layer in each (multi-)layer image; "largest-layer": select largest layer in each (multi-)layer image; "no-layer": do not select any layer from any image; --parameter=KEY1[=VALUE1][:KEY2[=VALUE2][:...]] set one or more KEY-VALUE pairs Expert mask generation options: --primary-seam-generator=ALGORITHM use main seam finder ALGORITHM, where ALGORITHM is "nearest-fea- ture-transform" or "graph-cut"; default: "graph-cut" --image-difference=ALGORITHM[:LUMINANCE-WEIGHT[:CHROMINANCE-WEIGHT]] use ALGORITHM for calculation of the difference image, where ALGO- RITHM is "max-hue-luminance" or "delta-e"; LUMINANCE-WEIGHT and CHROMINANCE-WEIGHT define the weights of lightness and color; de- fault: delta-e:1:1 --optimizer-weights=DISTANCE-WEIGHT[:MISMATCH-WEIGHT] 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[:DELTAE-MAX[:DELTAE-MIN[:K-MAX]]] 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 Information options: -h, --help print this help message and exit -V, --version output version information and exit --show-globbing-algorithms show all globbing algorithms --show-image-formats show all recognized image formats and their filename extensions --show-signature show who compiled the binary when and on which machine --show-software-components show the software components with which Enblend was compiled Enblend accepts arguments to any option in uppercase as well as in lower- case letters.
