A script facilitating multithreaded processing of lots of images using the power of G'MIC and various NCNN-Vulkan CLI tools, such as:
bip.sh [options] <input> <output> <cmd_file> [output_ext]
input: directory (batch mode) or file (single-file mode)
output: directory (any mode) or file (single-file mode)
cmd_file: file containing G'MIC or NCNN-Vulkan commands
output_ext: output extension/format (default=jpg)
Options:
-e <str>: input extension (default=*)
-q <num>: output JPEG quality (default=95)
-d <num>: input directory depth (default=1), -1 = infinite
-t <num>: number of simultaneous processes (default=number of CPU cores)
-n <str>: custom path to NCNN-Vulkan CLI tools
(default=/home/olaf/bin/ncnn-vulkan)
-g <str>: custom path to gmic
-r <num>: in single-file mode repeat processing producing <num> variants
from a single source (<output> must be a directory, files will have
names 00000001.[output_ext], 00000002.[output_ext], etc.)
Example: ./bip.sh -e jpg . output cmd.txt png
NCNN-Vulkan command example:
:waifu2x-ncnn-vulkan -n 2 -m models-upconv_7_photo
Don't add -i and -o as those will be added automatically
Notes:
- <cmd_file> should have one command at a line
- <cmd_file> can have #comments, empty lines and extra spaces
- <input> extension is case insensitive
- if <output> directory does not exists it will be created
- if <output> file already exists it will be overwritten silently
- commands can be taken from the G'MIC plugin for GIMP (just press Ctrl+C)
- alternatively you can use the stand-alone version of G'MIC
To use the G'MIC filters from the "Testing" section you must update the filter definitions in the G'MIC plugin and then copy the latest update file to your home directory naming it .gmic:
cp $(ls "$HOME/.config/gmic/"*.gmic | sort -n -r | head -n1) $HOME/.gmic
Or in case you're using GIMP in a Flatpak:
cp $(ls "$HOME/.var/app/org.gimp.GIMP/config/gmic"/*.gmic | sort -n -r | head -n1) $HOME/.gmic
