Superfast and minimal dependency pixel image comparasion tool built with rust.
riff <base_path> <diff_path>
<base_path> Path to image (jpeg or png) to compare from
<diff_path> Path to image (jpeg or png) to compare to
-o, --output Path to output image (jpeg or png) [default: ./output.png]
-a, --alpha Blending value of unchaged pixels, 0 alpha disables drawing of base image [default :0]
-t, --threshold Matching threshold, smaller values makes pixel comparison more sensitive [default: 0.1]
-c, --diffColour The color of differing pixels in [R, G, B, A] format [default: [218, 165, 32, 255]]
--viewPort The region within base image to compare to in [x, y, width, height] format. Useful when comparing differently sized images
