Lopttie is a Lottie optimization node CLI tool for compressing image sequences.
- Transcode!
- WebP!?
To install you can git clone this repo, run the following to to install Lopttie globally
npm install -g .
[TODO: add pkg instructions once published]
lopttie <path> <quality>
lopttie ./Galaxy.json --pngQuality 3
lopttie ./Galaxy.json --jpegQuality 75
The only required arguments to lopttie is the path to the Lottie/Bodymovin json to be compressed and one of the relevant quality arguments.
Lottie seqeunces can be either jpegs or pngs. Depending on which type the sequence you want to compress uses you will either pass the --jpegQuality
paramater or the --pngQuality
parameter.
If you don't know what type of image your animation uses, you can run
lopttie --noop --type
and lopttie will log the image type
See parameter list for more details.
##Parameters
lopttie <path>
<path> :
Path to uncompressed Lottie JSON file
--type: Boolean,
Will log the image type of the sequence,
recommended to run with --noop flag
--jpegQuality: Number,
REQUIRED IF image type is jpeg.
Takes an interger between 0-100
--pngQuality": Number,
REQUIRED IF image type is png.
Takes an interger between 1-11
--noop: Boolean,
Passing this flag will skip the main compression step,
this is handy if you want to log the --type,
and non-compression realted debuggin
--debug: Boolean,
Will log the detected arguments.
ADDITONALLY. Will write the last frame before
AND after compression for testing.
--output: String,
Path and name of exported JSON
TODO: -start will run loptie with no args, probably not helpful? -update will install/update the pkg with latest saved -watch will run update everytime index is saved. maybe rename to dev -test lol
