Lid
lo-fi image dithering
Lid performs fairly basic 1 bit image dithering. It converts an input image to grayscale and then dithers that image. It then optimizes the output and saves the file. The result is a reduced filesize, simple image, great for small apge sizes.
Dependencies
- Python3.x (built and tested with 3.6)
- PIL (python3 -m pip install Pillow)
Documentation
lid [option]... [source path] [output name]
Options:
-f = output format, defaults to the recommended setting: png
-m = mode, available: o4, o9, e. default: o4.
-q = quality, defaults to 90, only affects jpeg/jpg
source path = a path to an image file you want to dither
output name = the name of the file you would like to output, do not include file extension
Lid works best outputting png files from any input. You will get the smallest file with the best quality this way.
Modes
o4
This is the lowest quality mode. It will produce the smallest file size. It is a four level ordered dither.
o9
This mode produces medium quality dithering, it is still a very noticeable effect but not as harsh as o4. It is a none level ordered dither.
e
This is the highest quality mode. It uses an error diffusion dither. The file size will be the largest of the bunch, but should still be a good reduction from a regular full color photograph.
