NAME aaphoto - automatic color correction of photos SYNOPSYS aaphoto [option[s]] [source file[s]] DESCRIPTION Auto Adjust Photo is a tiny command-line image manipulation tool for automatic color cor‐ rection of photos. It tries to make the picture look better. The program does this by ana‐ lyzing the input image and then sets the most optimal contrast, gamma, color balance and saturation for it. The following image types are supported (thanks to JasPer, JPEG and PNG): mif, pnm / pgm / ppm, bmp, ras, jp2, jpc, jpg, png Quality settings can be applied only to jp2, jpc, jpg formats OPTIONS The following options are supported: -h --help Print this help -v --version Print version information -a --autoadjust Auto adjust the colors of the image -o --output Set output directory --overwrite Overwrite mode, the original source file is replaced --jpg JPG image output --jp2 JPEG 2000 image output --png PNG image output with alpha channel support --bmp BMP image output -r --resize Resize image taking the longer side in % or pixels --rotate90 Rotate image with 90 degrees clockwise --rotate180 Rotate image with 180 degrees --rotate270 Rotate image with 90 degrees counter-clockwise --flipx Mirror image horizontally --flipy Mirror image vertically --noexif Save image without EXIF info -q --quality Set image quality from 1 to 100 -t --threads Set number of working threads (default: autodetect) -s --silent Silent mode, no information printed during operation --quiet Same as -s, --silent -V --verbose Print verbose information about processing --test Print detailed test information into image EXAMPLES aaphoto folders aaphoto image.jpg aaphoto -a -r600 -q85 *.jpg aaphoto mydir aaphoto -V --resize70% image.png aaphoto --quality60 image.jp2 aaphoto image.jp2 REMARKS - auto adjust parameter is set by default without any other parameters - a _new filename will be generated without --overwrite parameter - every file is processed on directory input but not recursively - order of parameters does not matter - resize value can be set in percentage too - resize parameter should be less or equal than original - resize uses the best (and slowest) resampling method - default jpeg compression quality is 95% - EXIF information is restored in jpeg images by default - number of threads is set to the number of online processors by default LICENSE This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either ver‐ sion 3 of the License, or (at your option) any later version.
