pnglitcher (2022)

Project Rust crate

This crate contains a library allowing you to glitch PNG images. Most of the code comes from the PNG encoder written for the wonderful Image crate. The idea here is to provide a tool similar to the Ruby gem PNGlitch for Rust. The output of an image will not be the exact same as PNGlitch, it's simply used for inspiration.

At the moment this cargo is in heavy WIP, any release could introduce breaking changes so please use this crate for having fun and create weird looking PNG images.

How to use

Duplicate

Single filter

For each occurence this algorithm will copy data from another part of the image, then force the png to use a given filter.

Params

Examples

pnglitcher::duplicate("input1.png", "output1", 3,  1, 0);
pnglitcher::duplicate("input2.png", "output2", 0, 100, 1000);

Sample

Create a sample using duplicate algorithm for all filters for a given image

Params

Examples

pnglitcher::duplicate_sample("input1.png", "output1", 1, 0);
pnglitcher::duplicate_sample("input2.png", "output2", 100, 1000);

Replace

Single filter

For each occurence this algorithm will replace the data with 0, then force the png to use a given filter.

Params

Examples

pnglitcher::replace("input1.png", "output1", 0, 1);
pnglitcher::replace("input2.png", "output2", 4, 1);

Sample

Create a sample using duplicate algorithm for all filters for a given image

Params

Examples

pnglitcher::replace_sample("input1.png", "output1", 1);
pnglitcher::replace_sample("input2.png", "output2", 10);

Wrong filter

Single filter

Force the png encoder to use a wrong filter

Params

Examples

pnglitcher::wrong_filter("input1.png", "output1", 0);
pnglitcher::wrong_filter("input2.png", "output2", 2);

Sample

Create a sample using wrong filter algorithm for all filters for a given imageParams

Examples

pnglitcher::wrong_filter_sample("input1.png", "output1");
pnglitcher::wrong_filter_sample("input2.png", "output2");
