visual journal. current status: resizes and generates metadata for a directory of images
exiftool - propbably available in your system's package manager
npm run process-prod
npm run process-dev
npm run clean
it's JSON
img-src-dir the path of the directory containing your images
img-out-dir the path of the directory to write all your resized images
metadata-path the path to the file in which to write the image metadata
href-prefix the string with which to prefix all image paths
exif-props a list of exif properites to include in the output metadata
the default properties are CreateDate, ExposureTime, ScaleFactor35efl, FocalLength, LensType, Aperture, ISO, Model, GPSPosition, GPSAltitude, ImageWidth, and ImageHeight. Prop names are those used by exiftool.
breakpoints the breakpoints for resized images
an array of name, width pairs. the default breakpoints are [["tiny", 200], ["small", 556], ["medium", 804], ["large", 1000]]
metadata-format the format of the output metadata. transit, html, or atom. defaults to transit
html-tmpl the path of the template to be used for html output.
there is no default value. when metadata-format is html, this key is required. the string ##PHOTOS## in the template will be replaced with image metadata
exif-transforms arbitrary transformations of exif values
described as an array of key, value, new-value triplets. example use: cleaning up camera names.
"exif-transforms": [
["model", "Digimax A6", "Samsung Digimax A6"],
["model", "FE190/X750", "Olympus FE-190"],
]
node ./process/main.js /path/to/config
images in img-src-dir are symlinked into img-out-dir. images resized relative to breakpoints are written to img-out-dir.
metadata describing the images is written to metadata-path. in addtion to the keys specified in
exif-props, it includes the following keys:
file-created file created timestamp
file-modified file modified timestamp
sizes a list of images derived from breakpoints. href and label keys for each
srcset html srcset attribute value
height-scale the height of the image as a multiplier of it's width
href the url of the original image prefixed with href-prefix
keys are formatted relative to metatdata-format. not all keys are present in all formats
