COMMAND is the path to the script script file with all its arguments # as specified by the script in question. Do not include the input and output images. # If an argument is a color definition, then it can only be a color name or a hex color # without quotes. Other color specifications do not work. Also the script cannot handle # any other arguments that require quoting. If the path to the script in in your PATH # environment variable, then the path to the script may be left off. Use the script[.sh] # as it is on your system. COMMAND is a required argument. Enclose it all in single or # double quotes. # # -i inputfolder ... INPUTFOLDER is the path to the the folder of input images and must # include the folder name. The default is folder from which scriptbatch is called. # # -o outputfolder ... OUTPUTFOLDER is the path to the output image folder including the # folder name. The default is the same folder as the input folder. If the folder does # not already exist, it will be created. # # -f format ... FORMAT for filtering input images. Space and/or comma separate list. # The default is to process all files in the inputfolder. Typical formats are: # jpg, png, tiff (case insensitive). Example: "jpg,png" or "jpg png" or "jpg, png" # will only process jpg and png format images. # # -s suffix ... SUFFIX is the extension to add to the output images without the period. # The default is the same suffix as the input. Typical suffixes are jpg, png, tiff. # # -p path2imagemagick ... PATH2IMAGEMAGICK is the path to imagemagick convert/magick, # excluding convert or magick. The default assumes it is in your PATH environment # variable. Typical locations are: /usr/local/bin, /usr/bin, /opt/local/bin, etc. # # NOTE: The scriptbatch script can use commands for scripts that take one input and # one output only, respectively and do not use arguments that need quoting such as a # list of control points or color specifications with parentheses, such as rgb(...). # The exception is that colors may be specified as color names or hex values without # quoting. The hex value must include the leading # symbol. Some scripts can use control # points specified via a text file. Those scripts will work when using the textfile. # # EXAMPLES: All but the first (continued in the first 3 lines) assume that the # scriptbatch script is initiated from the current directory, the desktop, and which # has two folders, test1 and test2. All assume that the path2imagemagick is in the # PATH environment variable. Do not preface local directories with ./ # # /Users/fred/applications/ImageMagick-Scripts/bin/scriptbatch \ # -c "/Users/fred/applications/ImageMagick-Scripts/bin/2colorthresh" \ # -f png -s tiff -i /Users/fred/desktop/test1 -o /Users/fred/desktop/test2 # # scriptbatch -c "2colorthresh" -f png -s tiff -i test1 -o test2 # scriptbatch -c "textcleaner -g -e stretch -f 25 -o 20" -f tif -s jpg -i test1 -o test2 # scriptbatch -c "bordergrid -s 10 -t 2 -o 4 -d 1 -a 45 -b 0 -c #FFFFFF" -f png -s tiff -i ../desktop/test1 -o ../desktop/test2 # scriptbatch -c 'curves -c curve -f pointfile.txt' -f png -s tiff -i test1 -o test2 # # CAVEAT: No guarantee that this script will work on all platforms, # nor that trapping of inconsistent parameters is complete and # foolproof.
