j2k_to_image(1) converts jpeg2000 files j2k_to_image(1) NAME
j2k_to_image - This program reads in a jpeg2000 image and converts it to another image type. It is part of the OpenJPEG library. Valid input image extensions are .j2k, .jp2, .j2c, .jpt Valid output image extensions are .bmp, .pgm, .pgx, .png, .pnm, .ppm, .raw, .tga, .tif . For PNG resp. TIF it needs libpng resp. libtiff . SYNOPSIS
j2k_to_image -i infile.j2k -o outfile.png j2k_to_image -ImgDir images/ -OutFor bmp j2k_to_image -h Print help message and exit See JPWL OPTIONS for special options OPTIONS
-i name (jpeg2000 input file name) -l n n is the maximum number of quality layers to decode. See LAYERS below) -o name (output file name with extension) -r n (n is the highest resolution level to be discarded. See REDUCTION below) -x name (use name as index file and fill it) -ImgDir directory_name (directory containing input files) -OutFor ext (extension for output files) JPWL OPTIONS
Options usable only if the library has been compiled with -DUSE_JPWL -W c[=Nc] (Nc is the number of expected components in the codestream; default:3) -W t[=Nt] (Nt is the maximum number of tiles in the codestream; default:8192) -W c[=Nc], t[=Nt] (same as above) REDUCTION
Set the number of highest resolution levels to be discarded. The image resolution is effectively divided by 2 to the power of the number of discarded levels. The reduce factor is limited by the smallest total number of decomposition levels among tiles. TILES
Set the maximum number of quality layers to decode. If there are less quality layers than the specified number, all the quality layers are decoded. AUTHORS

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 correction of photos. It tries to make the picture look better. The program does this by analyzing the input image and then sets the most optimal contrast, gamma, color balance and satura- tion 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 AUTHORS
