ART(1) General Commands Manual ART(1) NAME ART - An advanced, cross-platform program for developing raw photos. DESCRIPTION ART is an advanced program for developing raw photos and for processing non-raw photos. It is non-destructive, makes use of OpenMP, supports all the cameras supported by dcraw and more, and carries out its calculations in a high precision 32-bit floating point engine. LINKS Website: https://artraweditor.github.io/ SYMBOLS <Chevrons> indicate parameters you can change. [Square brackets] mean the parameter is optional. The pipe symbol | indicates a choice of one or the other. The dash symbol - denotes a range of possible values. SYNOPSIS ART GUI ART <folder> Start File Browser inside folder. ART <file> Start Image Editor with file. ART CLI ART-cli -c <dir>|<files> Convert files in batch using default parame- ters. ART-cli <other options> -c <dir>|<files> Convert files in batch using your own settings. ART-cli [-o <output>|-O <output>] [-q] [-a] [-s|-S] [-p <one.arp> [-p <two.arp> ...] ] [-d] [ -j[1-100] [-js<1-3>] | [-b<8|16>] [-t[z] | [-n]] ] [-Y] -c <input> OPTIONS -c <files> Specify one or more input files. -c must be the last option. -o <file>|<dir> Set output file or folder. Saves output file alongside input file if -o is not specified. -O <file>|<dir> Set output file or folder and copy arp file into it. Saves output file alongside input file if -O is not specified. -q Quick-start mode. Does not load cached files to speedup start time. -a Process all supported image file types when specifying a folder, even those not currently selected in Preferences > File Browser > Parsed Extensions. -s Use the existing sidecar file to build the processing parameters, e.g. for photo.raw there should be a photo.raw.arp file in the same folder. If the sidecar file does not exist, neutral values will be used. -S Like -s but skip if the sidecar file does not exist. -p <file.arp> Specify processing profile to be used for all conver- sions. You can specify as many sets of "-p <file.arp>" options as you like, each will be built on top of the previous one, as ex- plained below. -d Use the default raw or non-raw processing profile as set in Preferences > Image Processing > Default Processing Pro- file -j[1-100] Specify output to be JPEG (default, if -t and -n are not set). Optionally, specify compression 1-100 (default value: 92). -js<1-3> Specify the JPEG chroma subsampling parameter, where: 1 = Best compression: 2x2, 1x1, 1x1 (4:2:0) Chroma halved vertically and horizontally. 2 = Balanced (default): 2x1, 1x1, 1x1 (4:2:2) Chroma halved horizontally. 3 = Best quality: 1x1, 1x1, 1x1 (4:4:4) No chroma subsampling. -b<8|16> Specify bit depth per channel (default value: 16 for TIFF, 8 for PNG). Only applies to TIFF and PNG output, JPEG is always 8. -t[z] Specify output to be TIFF. Uncompressed by default, or deflate compression with 'z'. -n Specify output to be compressed PNG. Compression is hard-coded to 6. -Y Overwrite output if present. Your arp files can be incomplete, ART will build the final values as fol- lows: 1- A new processing profile is created using neutral values, 2- If the "-d" option is set, the values are overridden by those found in the default raw or non-raw processing profile. 3- If one or more "-p" options are set, the values are overridden by those found in these processing profiles. 4- If the "-s" or "-S" options are set, the values are finally overridden by those found in the sidecar files. The processing profiles are processed in the order specified on the com- mand line. AUTHOR ART is a derivative of RawTherapee, developed by Alberto Griggio. RawTherapee was originally written by Gabor Horvath of Budapest, Hungary, before being re-licensed as free and open-source software in January 2010. The RawTherapee development team comprises of passionate people from all around the world. Jul 25, 2019 ART(1)
