Rust based Command line tool to diff images in 2 structurally similar folders and output diff images.
The value outputted represent a percentage of how much the amount of pixel data differs from the hightest possible value for that given image in each pixel.
- Support multiple format's of images (JPEG).
- Allow for a threshold to output diff file.
From the CLI WG
- Revise stdout & stderr efficiency (avoid flush by using a stream).
- Add logging (log crate)
- Add Progress bar (indicatif crate)
- Add types of output (convey crate)
- Generate a man page (clap crate)
img_diff -s path\to\images -d path\to\images\to\compare -f path\to\output\diff\images
Will go trough all the files in the -s dir and subdirectories and compare them to the ones in the -d outputting diff files if a difference is found to -f dir.
enables verbose mode and output to stderr in case of a difference found.
Usage in CI
img_diff -s path\to\images -d path\to\images\to\compare -f path\to\output\diff\images -v 2> results/output.txt
This will enable verbose output and enable the results of failed comparisons to be put into output.txt We can use this to enable CI with
if [[ -s results/output.txt ]]; then exit 1; else exit 0; fi

Removed Dssim and a bunch of other dependencies.
Now the value shown is a percentage. More details above.
Uniform value no matter the image type.
Fixed some issues and migrated to using tools as recommended by the CLI WG
- Migrated to StructOpt
- Migrated to assert_cmd
- Added human friendly panic
Removed all unwraps and provide error messages.
More typo fixes.
Updated future features with things from the CLI WG suggestions.
Formatted using cargo fmt.
Fixed clippy issues.
Fixed typos and updated docs.
Removed Multi-threaded flag making that the default.
