idiff

Barebones image differs.

Build steps, C version:

$ cc -g -O2 -march=native -pthread idiff.c -o idiff

idiff will use libspng if available (link -lspng), falling back to libpng if available (link -lpng), or stb_image from the ext/stb submodule as last resort.

Build steps, Go version:

$ rm idiff.c
$ go build

Usage:

$ idiff <left> <right> [diff.html]

Suggested workflow:

$ <generate known good images in good/>
$ while working ...
    $ <generate new images in bad/>
    $ idiff good bad && {start,open,xdg-open} diff.html
