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.
- Revise stdout & stderr efficiency (avoid flush by using a stream).
- Add Progress bar (indicatif crate)
- Add types of output (convey 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.
-v
enables verbose mode and output to stderr in case of a difference found.
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
